ADVERSE REACTIONS SECTION.

6 ADVERSE REACTIONS Serious cardiac reactions, including myocardial infarction, have occurred following the use of almotriptan (almotriptan malate) tablets. These reactions are extremely rare and most have been reported in patients with risk factors predictive of CAD. Reactions reported in association with triptans have included coronary artery vasospasm, transient myocardial ischemia, myocardial infarction, ventricular tachycardia, and ventricular fibrillation [see Contraindications (4.1) and Warnings and Precautions (5.1)].The following adverse reactions are discussed in more detail in other sections of the labeling:oRisk of Myocardial Ischemia and Infarction and Other Adverse Cardiac Events [see Warnings and Precautions (5.1)]oSensations of Pain, Tightness, Pressure in the Chest and/or Throat, Neck, and Jaw [see Warnings and Precautions (5.2)]oCerebrovascular Events and Fatalities [see Warnings and Precautions (5.3)]oOther Vasospasm-Related Events, Including Peripheral Vascular Ischemia and Colonic Ischemia [see Warnings and Precautions (5.4)]oSerotonin Syndrome [see Warnings and Precautions (5.5)]oIncreases in Blood Pressure [see Warnings and Precautions (5.7)]Adverse events were assessed in controlled clinical trials that included 1840 adult patients who received one or two doses of almotriptan tablets and 386 adult patients who received placebo. The most common adverse reactions during treatment with almotriptan tablets were nausea, somnolence, headache, paresthesia, and dry mouth. In long-term open-label studies where patients were allowed to treat multiple attacks for up to year, 5% (63 out of 1347 patients) withdrew due to adverse experiences.Adverse events were assessed in controlled clinical trials that included 362 adolescent patients who received almotriptan tablets and 172 adolescent patients who received placebo. The most common adverse reactions during treatment with almotriptan tablets were dizziness, somnolence, headache, paresthesia, nausea, and vomiting. In long-term, open-label study where patients were allowed to treat multiple attacks for up to year, 2% (10 out of 420 adolescent patients) withdrew due to adverse events.Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.. oRisk of Myocardial Ischemia and Infarction and Other Adverse Cardiac Events [see Warnings and Precautions (5.1)]. oSensations of Pain, Tightness, Pressure in the Chest and/or Throat, Neck, and Jaw [see Warnings and Precautions (5.2)]. oCerebrovascular Events and Fatalities [see Warnings and Precautions (5.3)]. oOther Vasospasm-Related Events, Including Peripheral Vascular Ischemia and Colonic Ischemia [see Warnings and Precautions (5.4)]. oSerotonin Syndrome [see Warnings and Precautions (5.5)]. oIncreases in Blood Pressure [see Warnings and Precautions (5.7)].

In the paragraphs that follow, the frequencies of less commonly reported adverse clinical reactions are presented. The reports include adverse reactions in five adult controlled studies and one adolescent controlled study. Variability associated with adverse reaction reporting, the terminology used to describe adverse reactions, etc., limit the value of the quantitative frequency estimates provided. Reaction frequencies are calculated as the number of patients who used almotriptan tablets and reported reaction divided by the total number of patients exposed to almotriptan tablets (n 3047, all doses). All reported reactions are included except those already listed in the previous table, those too general to be informative, and those not reasonably associated with the use of the drug. Reactions are further classified within system organ class and enumerated in order of decreasing frequency using the following definitions: frequent adverse reactions are those occurring in 1/100 or more patients, infrequent adverse reactions are those occurring in fewer than 1/100 to 1/1000 patients, and rare adverse reactions are those occurring in fewer than 1/1000 patients.Body: Frequent: Headache.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Carcinogenesis. Almotriptan was administered to mice and rats for up to 103 to 104 weeks at oral doses up to 250 mg/kg/day and 75 mg/kg/day, respectively. These doses were associated with plasma exposures (AUC) to parent drug that were approximately 40 and 80 times, in mice and rats respectively, the plasma AUC in humans at the maximum recommended human dose (MRHD) of 25 mg/day. Because of high mortality rates in both studies, which reached statistical significance in high-dose female mice, all female rats, all male mice, and high-dose female mice were terminated between weeks 96 and 98. There was no increase in tumors related to almotriptan administration.. Mutagenesis. Almotriptan was not mutagenic in two in vitro gene mutation assays, the Ames test, and the mouse lymphoma tk assay. Almotriptan was not clastogenic in an in vivo mouse micronucleus assay.. Impairment of Fertility. When male and female rats received almotriptan (25 mg/kg/day, 100 mg/kg/day, or 400 mg/kg/day) orally prior to and during mating and gestation, prolongation of the estrous cycle was observed at the mid-dose and greater, and fertility was impaired at the highest dose. Subsequent mating of treated with untreated animals indicated that the decrease in fertility was due to an effect on females. The no-effect dose for reproductive toxicity in rats (25 mg/kg/day) is approximately 10 times the MRHD on mg/m2 basis.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action. Almotriptan binds with high affinity to 5-HT1D, 5-HT1B, and 5-HT1F receptors. Almotriptan has weak affinity for 5-HT1A and 5-HT7 receptors, but has no significant affinity or pharmacological activity at 5-HT2, 5-HT3, 5-HT4, 5-HT6; alpha or beta adrenergic; adenosine (A1, A2); angiotensin (AT1, AT2); dopamine (D1, D2); endothelin (ETA, ETB); or tachykinin (NK1, NK2, NK3) binding sites.. 12.2 Pharmacodynamics. Current theories on the etiology of migraine headache suggest that symptoms are due to local cranial vasodilatation and/or to the release of vasoactive and pro-inflammatory peptides from sensory nerve endings in an activated trigeminal system. The therapeutic activity of almotriptan in migraine can most likely be attributed to agonist effects at 5-HT1B/1D receptors on the extracerebral, intracranial blood vessels that become dilated during migraine attack and on nerve terminals in the trigeminal system. Activation of these receptors results in cranial vessel constriction, inhibition of neuropeptide release, and reduced transmission in trigeminal pain pathways.. 12.3 Pharmacokinetics. Absorption. The absolute bioavailability of almotriptan is about 70%, with peak plasma levels occurring to hours after administration; food does not affect pharmacokinetics.. Distribution. Almotriptan is minimally protein bound (approximately 35%) and the mean apparent volume of distribution is approximately 180 to 200 liters.. Metabolism. Almotriptan is metabolized by two major and one minor pathways. Monoamine oxidase (MAO)-mediated oxidative deamination (approximately 27% of the dose), and cytochrome P450-mediated oxidation (approximately 12% of the dose) are the major routes of metabolism, while flavin monooxygenase is the minor route. MAO-A is responsible for the formation of the indoleacetic acid metabolite, whereas cytochrome P450 (3A4 and 2D6) catalyzes the hydroxylation of the pyrrolidine ring to an intermediate that is further oxidized by aldehyde dehydrogenase to the gamma-aminobutyric acid derivative. Both metabolites are inactive.. Excretion. Almotriptan has mean half-life of to hours. Almotriptan is eliminated primarily by renal excretion (about 75% of the oral dose), with approximately 40% of an administered dose excreted unchanged in urine. Renal clearance exceeds the glomerular filtration rate by approximately 3-fold, indicating an active mechanism. Approximately 13% of the administered dose is excreted via feces, both unchanged and metabolized.. Drug-Drug Interactions. All drug interaction studies were performed in healthy volunteers using single 12.5 mg dose of almotriptan and multiple doses of the other drug.. Monoamine Oxidase Inhibitors. Co-administration of almotriptan and moclobemide (150 mg twice daily for days) resulted in 27% decrease in almotriptan clearance and an increase in Cmax of approximately 6%. No dose adjustment is necessary.. Propranolol. Co-administration of almotriptan and propranolol (80 mg twice daily for days) resulted in no significant changes in the pharmacokinetics of almotriptan.. Fluoxetine. Co-administration of almotriptan and fluoxetine (60 mg daily for days), potent inhibitor of CYP2D6, had no effect on almotriptan clearance, but maximal concentrations of almotriptan were increased 18%. This difference is not clinically significant.. Verapamil. Co-administration of almotriptan and verapamil (120 mg sustained-release tablets twice daily for days), an inhibitor of CYP3A4, resulted in 20% increase in the area under the plasma concentration-time curve, and in 24% increase in maximal plasma concentrations of almotriptan. Neither of these changes is clinically significant. No dose adjustment is necessary.. Ketoconazole and Other Potent CYP3A4 Inhibitors. Co-administration of almotriptan and ketoconazole, potent CYP3A4 inhibitor, resulted in an approximately 60% increase in exposure of almotriptan. Increased exposures to almotriptan may be expected when almotriptan is used with other potent CYP3A4 inhibitors.. Special Populations. Geriatric. Renal and total clearance, and amount of drug excreted in the urine, were lower in elderly healthy volunteers (age 65 to 76 years) than in younger healthy volunteers (age 19 to 34 years), resulting in longer terminal half-life (3.7 hours vs. 3.2 hours) and 25% higher area under the plasma concentration-time curve in the elderly subjects. The differences, however, do not appear to be clinically significant.. Pediatric. pharmacokinetics study of almotriptan was conducted in adolescents (12 to 17 years) and adults (18 to 55 years) with or without history of migraine. No differences were observed in the rate or extent of absorption of almotriptan in adolescents compared with adults.. Gender. No significant gender differences were observed in pharmacokinetic parameters.. Race. No significant differences were observed in pharmacokinetic parameters between Caucasian and African-American volunteers.. Hepatic Impairment. The pharmacokinetics of almotriptan have not been assessed in patients with hepatic impairment. Based on the known mechanisms of clearance of almotriptan, the maximum decrease expected in almotriptan clearance due to hepatic impairment would be 60% [see Dosage and Administration (2.2)].. Renal Impairment. The clearance of almotriptan was approximately 65% lower in patients with severe renal impairment (Cl/F 19.8 L/hour; creatinine clearance between 10 and 30 mL/min) and approximately 40% lower in patients with moderate renal impairment (Cl/F 34.2 L/hour; creatinine clearance between 31 and 71 mL/min) than in healthy volunteers (Cl/F 57 L/hour). Maximal plasma concentrations of almotriptan increased by approximately 80% in these patients [see Dosage and Administration (2.3)].

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES 14.1 Adults. The efficacy of almotriptan tablets (almotriptan malate) was established in three multi-center, randomized, double-blind, placebo-controlled European trials. Patients enrolled in these studies were primarily female (86%) and Caucasian (more than 98%), with mean age of 41 years (range of 18 to 72). Patients were instructed to treat moderate to severe migraine headache. Two hours after taking one dose of study medication, patients evaluated their headache pain. If the pain had not decreased in severity to mild or no pain, the patient was allowed to take an escape medication. If the pain had decreased to mild or no pain at hours but subsequently increased in severity between and 24 hours, it was considered relapse and the patient was instructed to take second dose of study medication. Associated symptoms of nausea, vomiting, photophobia, and phonophobia were also evaluated.In these studies, the percentage of patients achieving response (mild or no pain) hours after treatment was significantly greater in patients who received either almotriptan tablets 6.25 mg or 12.5 mg, compared with those who received placebo. higher percentage of patients reported pain relief after treatment with the 12.5 mg dose than with the 6.25 mg dose. Doses greater than 12.5 mg did not lead to significantly better response. These results are summarized in Table 3.Table 3.

Estimated Probability of Achieving an Initial Headache Response (Mild or No Pain) in Hours in Adults This Kaplan-Meier plot is based on data obtained in the three placebo-controlled clinical trials that provided evidence of efficacy (Studies 1, 2, and 3). Patients not achieving pain relief by hours were censored at hours.For patients with migraine-associated photophobia, phonophobia, nausea, and vomiting at baseline, there was decreased incidence of these symptoms following administration of almotriptan tablets compared with placebo.Two to 24 hours following the initial dose of study medication, patients were allowed to take an escape medication or second dose of study medication for pain response. The estimated probability of patients taking escape medication or second dose of study medication over the 24 hours following the initial dose of study medication is shown in Figure 2.Figure 2. Estimated Probability of Adult Patients Taking Escape Medication or Second Dose of Study Medication Over the 24 Hours Following the Initial Dose of Study Treatment This Kaplan-Meier plot is based on data obtained in the three placebo-controlled trials that provided evidence of efficacy (Studies 1, 2, and 3). Patients not using additional treatment were censored at 24 hours. Remedication was not allowed within hours after the initial dose of almotriptan tablets.The efficacy of almotriptan tablets was unaffected by the presence of aura; by gender, weight, or age of the patient; or by concomitant use of common migraine prophylactic drugs (e.g., beta-blockers, calcium channel blockers, and tricyclic antidepressants); or oral contraceptives. There were insufficient data to assess the effect of race on efficacy.. Figure 1. Estimated Probability of Achieving an Initial Headache Response (Mild or No Pain) in Hours in Adults. Figure 2. Estimated Probability of Adult Patients Taking Escape Medication or Second Dose of Study Medication Over the 24 Hours Following the Initial Dose of Study Treatment. 14.2 Adolescents Age 12 to 17 Years The efficacy of almotriptan tablets in adolescent patients age 12 to 17 years was evaluated in double-blind, randomized, placebo-controlled study. Patients enrolled in that study had at least 1-year history of migraine attacks with or without aura usually lasting hours or more (when untreated). Patients enrolled in the study were primarily females (60%) and Caucasian (75%), while 15% of patients were black, and 10% were of other races. Patients were instructed to treat moderate to severe migraine headache. Two hours after taking one dose of study medication, patients evaluated their headache pain. Associated symptoms of nausea, photophobia, and phonophobia were also evaluated.In this study, the percentage of patients achieving pain relief response (mild or no pain) hours after treatment was statistically significantly greater in patients who received almotriptan tablets 6.25 mg or 12.5 mg compared with those who received placebo. There was no additional benefit on pain relief provided by the 12.5 mg dose. The 2-hour pain relief results are summarized in Table 4.Table 4.

DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS oDo not use almotriptan tablets and ergotamine-containing or ergot-type medications within 24 hours of each other (4.5, 7.1)oDo not use almotriptan tablets and other 5-HT1 agonist (e.g., triptans) within 24 hours of each other (4.6, 7.2)oSSRI or SNRI: life-threatening serotonin syndrome reported during combined use with triptans (5.5, 7.3)oKetoconazole: use single dose of almotriptan tablets 6.25 mg; maximum almotriptan tablets daily dose 12.5 mg (7.4). oDo not use almotriptan tablets and ergotamine-containing or ergot-type medications within 24 hours of each other (4.5, 7.1). oDo not use almotriptan tablets and other 5-HT1 agonist (e.g., triptans) within 24 hours of each other (4.6, 7.2). oSSRI or SNRI: life-threatening serotonin syndrome reported during combined use with triptans (5.5, 7.3). oKetoconazole: use single dose of almotriptan tablets 6.25 mg; maximum almotriptan tablets daily dose 12.5 mg (7.4). 7.1 Ergot-Containing Drugs. These drugs have been reported to cause prolonged vasospastic reactions. Because, in theory, vasospastic effects may be additive, ergotamine-containing or ergot-type medications (like dihydroergotamine, ergotamine tartrate, or methysergide) and almotriptan tablets (almotriptan malate) should not be used within 24 hours of each other [see Contraindications (4.5)].. 7.2 5-HT1 Agonists (e.g., Triptans). Concomitant use of other 5-HT1 agonists (e.g., triptans) within 24 hours of treatment with almotriptan tablets is contraindicated [see Contraindications (4.6)].. 7.3 Selective Serotonin Reuptake Inhibitors/Serotonin Norepinephrine Reuptake Inhibitors. Cases of life-threatening serotonin syndrome have been reported during combined use of triptans and selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) [see Warnings and Precautions (5.5), Clinical Pharmacology (12.3)].. 7.4 Ketoconazole and Other Potent CYP3A4 Inhibitors. Co-administration of almotriptan and oral ketoconazole, potent CYP3A4 inhibitor, resulted in an approximately 60% increase in exposure of almotriptan. Increased exposures to almotriptan may be expected when almotriptan is used concomitantly with other potent CYP3A4 inhibitors [see Clinical Pharmacology (12.3)].In patients concomitantly using potent CYP3A4 inhibitors, the recommended starting dose of almotriptan tablets is 6.25 mg. The maximum daily dose should not exceed 12.5 mg within 24-hour period. Concomitant use of almotriptan tablets and potent CYP3A4 inhibitors should be avoided in patients with renal or hepatic impairment [see Clinical Pharmacology (12.3)].

GERIATRIC USE SECTION.

8.5 Geriatric Use Clinical studies of almotriptan tablets did not include sufficient numbers of subjects age 65 and over to determine whether they respond differently from younger subjects. Clearance of almotriptan was lower in elderly volunteers than in younger individuals, but there were no observed differences in the safety and tolerability between the two populations [see Clinical Pharmacology (12.3)]. In general, dose selection for an elderly patient should be cautious, usually starting at the low dose, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. The recommended dose of almotriptan tablets for elderly patients with normal renal function for their age is the same as that recommended for younger adults.

INFORMATION FOR PATIENTS SECTION.

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information).Drug Interactions: Advise patients to talk with their physician or pharmacist before taking any new medicines, including prescription and non-prescription drugs and supplements [see Contraindications (4.5) and (4.6) and Drug Interactions (7)].Hypersensitivity: Inform patients to tell their physician if they develop rash, itching, or breathing difficulties after taking almotriptan tablets [see Warnings and Precautions (5.8)].Risk of Myocardial Ischemia and/or Infarction, Other Adverse Cardiac Events, Other Vasospasm-Related Events, and Cerebrovascular Events: Inform patients that almotriptan tablets may cause serious cardiovascular side effects such as myocardial infarction or stroke, which may result in hospitalization and even death. Although serious cardiovascular events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, or slurring of speech, and should ask for medical advice when observing any indicative signs or symptoms. Apprise the patient of the importance of this follow-up [see Warnings and Precautions (5.1), (5.2), (5.3), and (5.4)].Serotonin Syndrome: Caution patients about the risk of serotonin syndrome with the use of almotriptan tablets or other triptans, particularly during combined use with selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) [see Warnings and Precautions (5.5)].Medication Overuse Headache: Inform patients that use of acute migraine drugs for 10 or more days per month may lead to an exacerbation of headache and encourage patients to record headache frequency and drug use (e.g., by keeping headache diary) [see Warnings and Precautions (5.6)].Pregnancy: Advise patients to notify their physician if they become pregnant during treatment or intend to become pregnant [see Use in Specific Populations (8.1)].Nursing Mothers: Advise patients to notify their physician if they are breastfeeding or plan to breastfeed [see Use in Specific Populations (8.3)].Ability to Operate Machinery or Vehicles: Counsel patients that almotriptan tablets may cause dizziness, somnolence, visual disturbances, and other CNS symptoms that can interfere with driving or operating machinery. Accordingly, advise the patient not to drive, operate complex machinery, or engage in other hazardous activities until they have gained sufficient experience with almotriptan tablets to gauge whether they affect their mental or visual performance adversely.

LABOR & DELIVERY SECTION.

8.2 Labor and Delivery. The effect of almotriptan tablets on labor and delivery in humans is unknown.

MECHANISM OF ACTION SECTION.

12.1 Mechanism of Action. Almotriptan binds with high affinity to 5-HT1D, 5-HT1B, and 5-HT1F receptors. Almotriptan has weak affinity for 5-HT1A and 5-HT7 receptors, but has no significant affinity or pharmacological activity at 5-HT2, 5-HT3, 5-HT4, 5-HT6; alpha or beta adrenergic; adenosine (A1, A2); angiotensin (AT1, AT2); dopamine (D1, D2); endothelin (ETA, ETB); or tachykinin (NK1, NK2, NK3) binding sites.

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Carcinogenesis. Almotriptan was administered to mice and rats for up to 103 to 104 weeks at oral doses up to 250 mg/kg/day and 75 mg/kg/day, respectively. These doses were associated with plasma exposures (AUC) to parent drug that were approximately 40 and 80 times, in mice and rats respectively, the plasma AUC in humans at the maximum recommended human dose (MRHD) of 25 mg/day. Because of high mortality rates in both studies, which reached statistical significance in high-dose female mice, all female rats, all male mice, and high-dose female mice were terminated between weeks 96 and 98. There was no increase in tumors related to almotriptan administration.. Mutagenesis. Almotriptan was not mutagenic in two in vitro gene mutation assays, the Ames test, and the mouse lymphoma tk assay. Almotriptan was not clastogenic in an in vivo mouse micronucleus assay.. Impairment of Fertility. When male and female rats received almotriptan (25 mg/kg/day, 100 mg/kg/day, or 400 mg/kg/day) orally prior to and during mating and gestation, prolongation of the estrous cycle was observed at the mid-dose and greater, and fertility was impaired at the highest dose. Subsequent mating of treated with untreated animals indicated that the decrease in fertility was due to an effect on females. The no-effect dose for reproductive toxicity in rats (25 mg/kg/day) is approximately 10 times the MRHD on mg/m2 basis.

NURSING MOTHERS SECTION.

8.3 Nursing Mothers It is not known whether almotriptan is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when almotriptan tablets are administered to nursing woman. Levels of almotriptan in rat milk were up to times higher than in rat plasma.

OVERDOSAGE SECTION.

10 OVERDOSAGE 10.1 Signs and Symptoms. Patients and volunteers receiving single oral doses of 100 mg to 150 mg of almotriptan did not experience significant adverse events. Six additional normal volunteers received single oral doses of 200 mg without serious adverse events. During clinical trials with almotriptan tablets (almotriptan malate), one patient ingested 62.5 mg in 5-hour period and another patient ingested 100 mg in 38-hour period. Neither patient experienced adverse reactions.Based on the pharmacology of triptans, hypertension or other more serious cardiovascular symptoms could occur after overdosage.. 10.2 Recommended Treatment. There is no specific antidote to almotriptan tablets. In cases of severe intoxication, intensive care procedures are recommended, including establishing and maintaining patent airway, ensuring adequate oxygenation and ventilation, and monitoring and support of the cardiovascular system. Clinical and electrocardiographic monitoring should be continued for at least 20 hours even if clinical symptoms are not observed.It is unknown what effect hemodialysis or peritoneal dialysis has on plasma concentrations of almotriptan.

PEDIATRIC USE SECTION.

8.4 Pediatric Use Safety and efficacy of almotriptan tablets in pediatric patients under the age of 12 years have not been established. The pharmacokinetics, efficacy, and safety of almotriptan tablets have been evaluated in adolescent patients, age 12 to 17 years [see Clinical Pharmacology (12.3) and Clinical Studies (14.2)].In clinical study, almotriptan tablets 6.25 mg and 12.5 mg were found to be effective for the relief of migraine headache pain in adolescent patients age 12 to 17 years. Efficacy on migraine-associated symptoms (nausea, photophobia, and phonophobia) was not established. The most common adverse reactions (incidence of >= 1%) associated with almotriptan tablet treatment were dizziness, somnolence, headache, paresthesia, nausea, and vomiting [see Adverse Reactions (6.1)]. The safety and tolerability profile of almotriptan tablet treatment in adolescents is similar to the profile observed in adults.Postmarketing experience with other triptans include limited number of reports that describe pediatric patients who have experienced clinically serious adverse events that are similar in nature to those reported rarely in adults.

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics. Current theories on the etiology of migraine headache suggest that symptoms are due to local cranial vasodilatation and/or to the release of vasoactive and pro-inflammatory peptides from sensory nerve endings in an activated trigeminal system. The therapeutic activity of almotriptan in migraine can most likely be attributed to agonist effects at 5-HT1B/1D receptors on the extracerebral, intracranial blood vessels that become dilated during migraine attack and on nerve terminals in the trigeminal system. Activation of these receptors results in cranial vessel constriction, inhibition of neuropeptide release, and reduced transmission in trigeminal pain pathways.

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. Absorption. The absolute bioavailability of almotriptan is about 70%, with peak plasma levels occurring to hours after administration; food does not affect pharmacokinetics.. Distribution. Almotriptan is minimally protein bound (approximately 35%) and the mean apparent volume of distribution is approximately 180 to 200 liters.. Metabolism. Almotriptan is metabolized by two major and one minor pathways. Monoamine oxidase (MAO)-mediated oxidative deamination (approximately 27% of the dose), and cytochrome P450-mediated oxidation (approximately 12% of the dose) are the major routes of metabolism, while flavin monooxygenase is the minor route. MAO-A is responsible for the formation of the indoleacetic acid metabolite, whereas cytochrome P450 (3A4 and 2D6) catalyzes the hydroxylation of the pyrrolidine ring to an intermediate that is further oxidized by aldehyde dehydrogenase to the gamma-aminobutyric acid derivative. Both metabolites are inactive.. Excretion. Almotriptan has mean half-life of to hours. Almotriptan is eliminated primarily by renal excretion (about 75% of the oral dose), with approximately 40% of an administered dose excreted unchanged in urine. Renal clearance exceeds the glomerular filtration rate by approximately 3-fold, indicating an active mechanism. Approximately 13% of the administered dose is excreted via feces, both unchanged and metabolized.. Drug-Drug Interactions. All drug interaction studies were performed in healthy volunteers using single 12.5 mg dose of almotriptan and multiple doses of the other drug.. Monoamine Oxidase Inhibitors. Co-administration of almotriptan and moclobemide (150 mg twice daily for days) resulted in 27% decrease in almotriptan clearance and an increase in Cmax of approximately 6%. No dose adjustment is necessary.. Propranolol. Co-administration of almotriptan and propranolol (80 mg twice daily for days) resulted in no significant changes in the pharmacokinetics of almotriptan.. Fluoxetine. Co-administration of almotriptan and fluoxetine (60 mg daily for days), potent inhibitor of CYP2D6, had no effect on almotriptan clearance, but maximal concentrations of almotriptan were increased 18%. This difference is not clinically significant.. Verapamil. Co-administration of almotriptan and verapamil (120 mg sustained-release tablets twice daily for days), an inhibitor of CYP3A4, resulted in 20% increase in the area under the plasma concentration-time curve, and in 24% increase in maximal plasma concentrations of almotriptan. Neither of these changes is clinically significant. No dose adjustment is necessary.. Ketoconazole and Other Potent CYP3A4 Inhibitors. Co-administration of almotriptan and ketoconazole, potent CYP3A4 inhibitor, resulted in an approximately 60% increase in exposure of almotriptan. Increased exposures to almotriptan may be expected when almotriptan is used with other potent CYP3A4 inhibitors.. Special Populations. Geriatric. Renal and total clearance, and amount of drug excreted in the urine, were lower in elderly healthy volunteers (age 65 to 76 years) than in younger healthy volunteers (age 19 to 34 years), resulting in longer terminal half-life (3.7 hours vs. 3.2 hours) and 25% higher area under the plasma concentration-time curve in the elderly subjects. The differences, however, do not appear to be clinically significant.. Pediatric. pharmacokinetics study of almotriptan was conducted in adolescents (12 to 17 years) and adults (18 to 55 years) with or without history of migraine. No differences were observed in the rate or extent of absorption of almotriptan in adolescents compared with adults.. Gender. No significant gender differences were observed in pharmacokinetic parameters.. Race. No significant differences were observed in pharmacokinetic parameters between Caucasian and African-American volunteers.. Hepatic Impairment. The pharmacokinetics of almotriptan have not been assessed in patients with hepatic impairment. Based on the known mechanisms of clearance of almotriptan, the maximum decrease expected in almotriptan clearance due to hepatic impairment would be 60% [see Dosage and Administration (2.2)].. Renal Impairment. The clearance of almotriptan was approximately 65% lower in patients with severe renal impairment (Cl/F 19.8 L/hour; creatinine clearance between 10 and 30 mL/min) and approximately 40% lower in patients with moderate renal impairment (Cl/F 34.2 L/hour; creatinine clearance between 31 and 71 mL/min) than in healthy volunteers (Cl/F 57 L/hour). Maximal plasma concentrations of almotriptan increased by approximately 80% in these patients [see Dosage and Administration (2.3)].

PREGNANCY SECTION.

8.1 Pregnancy. Pregnancy Category C. In animal studies, almotriptan produced developmental toxicity (increased embryolethality and fetal skeletal variations, and decreased offspring body weight) at doses greater than those used clinically. There are no adequate and well-controlled studies in pregnant women; therefore, almotriptan tablets (almotriptan malate) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.When almotriptan (125 mg/kg/day, 250 mg/kg/day, 500 mg/kg/day, or 1000 mg/kg/day) was administered orally to pregnant rats throughout the period of organogenesis, increased incidences of fetal skeletal variations (decreased ossification) were noted at dose of 250 mg/kg/day or greater and an increase in embryolethality was seen at the highest dose. The no-effect dose for embryo-fetal developmental toxicity in rats (125 mg/kg/day) is approximately 100 times the maximum recommended human dose (MRHD) of 25 mg/day on body surface area (mg/m2) basis. Similar studies in pregnant rabbits conducted with almotriptan (oral doses of mg/kg/day, 20 mg/kg/day, or 60 mg/kg/day) demonstrated increases in embryolethality at the highest dose. The no-effect dose for embryo-fetal developmental toxicity in rabbits (20 mg/kg/day) is approximately 15 times the MRHD on mg/m2 basis. When almotriptan (25 mg/kg/day, 100 mg/kg/day, or 400 mg/kg/day) was administered orally to rats throughout the periods of gestation and lactation, gestation length was increased and litter size and offspring body weight were decreased at the highest dose. The decrease in pup weight persisted throughout lactation. The no-effect dose in this study (100 mg/kg/day) is 40 times the MRHD on mg/m2 basis.

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS oPregnancy: based on animal data, may cause fetal harm (8.1)oNursing mothers: use almotriptan tablets with caution (8.3)oPediatric use: almotriptan tablets have not been studied in children under 12 years (8.4)oGeriatric use: insufficient safety and efficacy data; use with caution, usually starting with the 6.25 mg dose (8.5)oHepatic impairment: use single 6.25 mg tablet as starting dose; maximum daily dose 12.5 mg (2.2, 8.6)oSevere renal impairment: use single 6.25 mg tablet as starting dose; maximum daily dose 12.5 mg (2.3, 8.7). oPregnancy: based on animal data, may cause fetal harm (8.1). oNursing mothers: use almotriptan tablets with caution (8.3). oPediatric use: almotriptan tablets have not been studied in children under 12 years (8.4). oGeriatric use: insufficient safety and efficacy data; use with caution, usually starting with the 6.25 mg dose (8.5). oHepatic impairment: use single 6.25 mg tablet as starting dose; maximum daily dose 12.5 mg (2.2, 8.6). oSevere renal impairment: use single 6.25 mg tablet as starting dose; maximum daily dose 12.5 mg (2.3, 8.7). 8.1 Pregnancy. Pregnancy Category C. In animal studies, almotriptan produced developmental toxicity (increased embryolethality and fetal skeletal variations, and decreased offspring body weight) at doses greater than those used clinically. There are no adequate and well-controlled studies in pregnant women; therefore, almotriptan tablets (almotriptan malate) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.When almotriptan (125 mg/kg/day, 250 mg/kg/day, 500 mg/kg/day, or 1000 mg/kg/day) was administered orally to pregnant rats throughout the period of organogenesis, increased incidences of fetal skeletal variations (decreased ossification) were noted at dose of 250 mg/kg/day or greater and an increase in embryolethality was seen at the highest dose. The no-effect dose for embryo-fetal developmental toxicity in rats (125 mg/kg/day) is approximately 100 times the maximum recommended human dose (MRHD) of 25 mg/day on body surface area (mg/m2) basis. Similar studies in pregnant rabbits conducted with almotriptan (oral doses of mg/kg/day, 20 mg/kg/day, or 60 mg/kg/day) demonstrated increases in embryolethality at the highest dose. The no-effect dose for embryo-fetal developmental toxicity in rabbits (20 mg/kg/day) is approximately 15 times the MRHD on mg/m2 basis. When almotriptan (25 mg/kg/day, 100 mg/kg/day, or 400 mg/kg/day) was administered orally to rats throughout the periods of gestation and lactation, gestation length was increased and litter size and offspring body weight were decreased at the highest dose. The decrease in pup weight persisted throughout lactation. The no-effect dose in this study (100 mg/kg/day) is 40 times the MRHD on mg/m2 basis.. 8.2 Labor and Delivery. The effect of almotriptan tablets on labor and delivery in humans is unknown.. 8.3 Nursing Mothers It is not known whether almotriptan is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when almotriptan tablets are administered to nursing woman. Levels of almotriptan in rat milk were up to times higher than in rat plasma.. 8.4 Pediatric Use Safety and efficacy of almotriptan tablets in pediatric patients under the age of 12 years have not been established. The pharmacokinetics, efficacy, and safety of almotriptan tablets have been evaluated in adolescent patients, age 12 to 17 years [see Clinical Pharmacology (12.3) and Clinical Studies (14.2)].In clinical study, almotriptan tablets 6.25 mg and 12.5 mg were found to be effective for the relief of migraine headache pain in adolescent patients age 12 to 17 years. Efficacy on migraine-associated symptoms (nausea, photophobia, and phonophobia) was not established. The most common adverse reactions (incidence of >= 1%) associated with almotriptan tablet treatment were dizziness, somnolence, headache, paresthesia, nausea, and vomiting [see Adverse Reactions (6.1)]. The safety and tolerability profile of almotriptan tablet treatment in adolescents is similar to the profile observed in adults.Postmarketing experience with other triptans include limited number of reports that describe pediatric patients who have experienced clinically serious adverse events that are similar in nature to those reported rarely in adults.. 8.5 Geriatric Use Clinical studies of almotriptan tablets did not include sufficient numbers of subjects age 65 and over to determine whether they respond differently from younger subjects. Clearance of almotriptan was lower in elderly volunteers than in younger individuals, but there were no observed differences in the safety and tolerability between the two populations [see Clinical Pharmacology (12.3)]. In general, dose selection for an elderly patient should be cautious, usually starting at the low dose, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. The recommended dose of almotriptan tablets for elderly patients with normal renal function for their age is the same as that recommended for younger adults.. 8.6 Hepatic Impairment The recommended starting dose of almotriptan tablets in patients with hepatic impairment is 6.25 mg. The maximum daily dose should not exceed 12.5 mg over 24-hour period [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3)].. 8.7 Renal Impairment. The recommended starting dose of almotriptan tablets in patients with severe renal impairment is 6.25 mg. The maximum daily dose should not exceed 12.5 mg over 24-hour period [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].

In very rare cases, serious cardiovascular events have been reported in association with almotriptan tablet use in the absence of known cardiovascular disease. If almotriptan tablets are considered, patients should first have cardiovascular evaluation. If the evaluation is satisfactory, first dose should take place in physicians office setting (5.1). oSensations of pain, tightness, pressure, and heaviness in the chest, throat, neck, and jaw: generally not associated with myocardial ischemia, but patients with signs or symptoms suggestive of angina should be evaluated for the presence of CAD (5.2). oCerebrovascular events, some fatal (5.3). oGastrointestinal ischemic events and peripheral vasospastic reactions (e.g., Raynauds syndrome) (5.4). oPotentially life-threatening serotonin syndrome, particularly in combination with selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs).

Cardiac Events and Fatalities with 5-HT1 Agonists. Serious adverse cardiac events, including acute myocardial infarction, have been reported within few hours following administration of almotriptan tablets (almotriptan malate). Life-threatening disturbances of cardiac rhythm and death have been reported within few hours following the administration of other triptans. Considering the extent of use of triptans in patients with migraine, the incidence of these events is extremely low.Almotriptan tablets can cause coronary vasospasm; at least one of these events occurred in patient with no cardiac history and with documented absence of coronary artery disease. Because of the close proximity of the events to use of almotriptan tablets, causal relationship cannot be excluded. Patients who experience signs or symptoms suggestive of angina following dosing should be evaluated for the presence of coronary artery disease (CAD) or predisposition to Prinzmetals variant angina before receiving additional doses of medication, and should be monitored electrocardiographically if dosing is resumed and similar symptoms recur.. Premarketing Experience with Almotriptan Tablets in Adults. Among the 3865 subjects/patients who received almotriptan tablets in premarketing clinical trials, one patient was hospitalized for observation after scheduled electrocardiogram (ECG) was found to be abnormal (negative T-waves on the left leads) 48 hours after taking single 6.25 mg dose of almotriptan. The patient, 48-year-old female, had previously taken three other doses for earlier migraine attacks. Myocardial enzymes at the time of the abnormal ECG were normal. The patient was diagnosed as having had myocardial ischemia and that she had family history of coronary disease. An ECG performed days later was normal, as was follow-up coronary angiography. The patient recovered without incident.. Postmarketing Experience with Almotriptan Tablets in Adults. Serious cardiovascular events have been reported in association with the use of almotriptan tablets. The uncontrolled nature of postmarketing surveillance, however, makes it impossible to definitively determine the proportion of the reported cases that were actually caused by almotriptan or to reliably assess causation in individual cases [see Adverse Reactions (6.3)].. Patients with Documented Coronary Artery Disease. Because of the potential of this class of compound (5-HT1 agonists) to cause coronary vasospasm, almotriptan tablets should not be given to patients with documented ischemic or vasospastic coronary artery disease [see Contraindications (4.1)].. Patients with Risk Factors for CAD. It is strongly recommended that almotriptan tablets not be given to patients in whom unrecognized CAD is predicted by the presence of risk factors (e.g., hypertension, hypercholesterolemia, smoker, obesity, diabetes, strong family history of CAD, female with surgical or physiological menopause, or male over 40 years of age) unless cardiovascular evaluation provides satisfactory clinical evidence that the patient is reasonably free of coronary artery and ischemic myocardial disease or other significant underlying cardiovascular disease. The sensitivity of cardiac diagnostic procedures to detect cardiovascular disease or predisposition to coronary artery vasospasm is modest, at best. If, during the cardiovascular evaluation, the patients medical history, electrocardiographic or other investigations reveal findings indicative of, or consistent with, coronary artery vasospasm or myocardial ischemia, almotriptan tablets should not be administered [see Contraindications (4.1)].For patients with risk factors predictive of CAD, who are determined to have satisfactory cardiovascular evaluation, it is strongly recommended that administration of the first dose of almotriptan tablets take place in the setting of physicians office or similar medically staffed and equipped facility unless the patient has previously received almotriptan tablets. Because cardiac ischemia can occur in the absence of clinical symptoms, consideration should be given to obtaining on the first occasion of use an ECG during the interval immediately following almotriptan tablets, in these patients with risk factors. It is recommended that patients who are intermittent long-term users of almotriptan tablets and who have or acquire risk factors predictive of CAD, as described above, undergo periodic interval cardiovascular evaluation as they continue to use almotriptan tablets.The systematic approach described above is intended to reduce the likelihood that patients with unrecognized cardiovascular disease will be inadvertently exposed to almotriptan tablets. The ability of cardiac diagnostic procedures to detect all cardiovascular diseases or predisposition to coronary artery vasospasm is modest at best. Cardiovascular events associated with triptan treatment have occurred in patients with no cardiac history and with documented absence of coronary artery disease.. 5.2 Sensations of Pain, Tightness, Pressure in the Chest and/or Throat, Neck, and Jaw. As with other 5-HT1 agonists, sensations of tightness, pain, pressure, and heaviness in the precordium, throat, neck, and jaw have been reported after treatment with almotriptan tablets. Because 5-HT1 agonists may cause coronary vasospasm, patients who experience signs or symptoms suggestive of angina following dosing should be evaluated for the presence of CAD or predisposition to Prinzmetals variant angina before receiving additional doses of medication, and should be monitored electrocardiographically if dosing is resumed and similar symptoms occur. Patients shown to have CAD and those with Prinzmetals variant angina should not receive 5-HT1 agonists [see Contraindications (4.1) and Warnings and Precautions (5.1)].. 5.3 Cerebrovascular Events and Fatalities Cerebral hemorrhage, subarachnoid hemorrhage, stroke, and other cerebrovascular events have been reported in patients treated with other triptans and some events have resulted in fatalities. In number of cases, it appeared possible that the cerebrovascular events were primary, the triptan having been administered in the incorrect belief that the symptoms experienced were consequence of migraine, when they were not. As with other acute migraine therapies, before treating headaches in patients not previously diagnosed as migraineurs and in migraineurs who present with atypical symptoms, care should be taken to exclude other potentially serious neurological conditions. It should be noted that patients with migraine may be at increased risk of certain cerebrovascular events (e.g., stroke, hemorrhage, and transient ischemic attack) [see Contraindications (4.2)].. 5.4 Other Vasospasm-Related Events, Including Peripheral Vascular Ischemia and Colonic Ischemia. Triptans, including almotriptan tablets, may cause vasospastic reactions other than coronary artery vasospasm, such as peripheral and gastrointestinal vascular ischemia with abdominal pain and bloody diarrhea. Very rare reports of transient and permanent blindness and significant partial vision loss have been reported with the use of triptans. Visual disorders may also be part of migraine attack. Patients who experience symptoms or signs suggestive of decreased arterial flow following the use of any triptan, such as ischemic bowel syndrome or Raynauds syndrome, are candidates for further evaluation [see Contraindications (4.3)].. 5.5 Serotonin Syndrome The development of potentially life-threatening serotonin syndrome may occur with triptans, including almotriptan tablets, particularly during combined use with selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs). If concomitant treatment with almotriptan tablets and an SSRI (e.g., fluoxetine, paroxetine, sertraline, fluvoxamine, citalopram, escitalopram) or SNRI (e.g., venlafaxine, duloxetine) is clinically warranted, careful observation of the patient is advised, particularly during treatment initiation and dose increases. Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, coma), autonomic instability (e.g., tachycardia, labile blood pressure, hyperthermia), neuromuscular aberrations (e.g., hyperreflexia, incoordination) and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea) [see Drug Interactions (7.3)].. 5.6 Medication Overuse Headache. Overuse of acute migraine drugs (e.g., ergotamine, triptans, opioids, or combination of these drugs for 10 or more days per month) may lead to exacerbation of headache (medication overuse headache). Medication overuse headache may present as migraine-like daily headaches or as marked increase in frequency of migraine attacks. Detoxification of patients, including withdrawal of the overused drugs, and treatment of withdrawal symptoms (which often includes transient worsening of headache) may be necessary.. 5.7 Increases in Blood Pressure As with other triptans, significant elevations in systemic blood pressure have been reported on rare occasions with almotriptan tablet use in patients with and without history of hypertension; very rarely these increases in blood pressure have been associated with significant clinical events. Almotriptan tablets are contraindicated in patients with uncontrolled hypertension [see Contraindications (4.4)]. In normotensive healthy subjects and patients with hypertension controlled by medication, small, but clinically insignificant, increases in mean systolic (0.21 and 4.87 mm Hg, respectively) and diastolic (1.35 and 0.26 mm Hg, respectively) blood pressure relative to placebo were seen over the first hours after oral administration of 12.5 mg of almotriptan.An 18% increase in mean pulmonary artery pressure was seen following dosing with another triptan in study evaluating subjects undergoing cardiac catheterization.. 5.8 Hypersensitivity to Sulfonamides Caution should be exercised when prescribing almotriptan tablets to patients with known hypersensitivity to sulfonamides. The chemical structure of almotriptan contains sulfonyl group, which is structurally different from sulfonamide. Cross-sensitivity to almotriptan in patients allergic to sulfonamides has not been systematically evaluated.. 5.9 Impaired Hepatic or Renal Function. Almotriptan tablets should be administered with caution to patients with diseases that may alter the absorption, metabolism, or excretion of drugs, such as those with impaired hepatic or renal function [see Dosage and Administration (2.2), (2.3) and Clinical Pharmacology (12.3)].. 5.10 Binding to Melanin-Containing Tissues. When pigmented rats were given single oral dose of mg/kg of radiolabeled almotriptan, the elimination half-life of radioactivity from the eye was 22 days. This finding suggests that almotriptan and/or its metabolites may bind to melanin in the eye. Because almotriptan could accumulate in melanin-rich tissues over time, there is the possibility that it could cause toxicity in these tissues with extended use. However, no adverse retinal effects related to treatment with almotriptan were noted in 52-week toxicity study in dogs given up to 12.5 mg/kg/day (resulting in exposure [AUC] to parent drug approximately 20 times that in humans receiving the maximum recommended human dose of 25 mg/day). Although no systematic monitoring of ophthalmologic function was undertaken in clinical trials, and no specific recommendations for ophthalmologic monitoring are offered, prescribers should be aware of the possibility of long-term ophthalmologic effects.. 5.11 Corneal Opacities. Three male dogs (out of total of 14 treated) in 52-week toxicity study of oral almotriptan developed slight corneal opacities that were noted after 51 weeks, but not after 25 weeks of treatment. The doses at which this occurred were mg/kg/day, mg/kg/day, and 12.5 mg/kg/day. The opacity reversed after 4-week drug-free period in the affected dog treated with the highest dose. Systemic exposure (plasma AUC) to parent drug at mg/kg/day was approximately 2.5 times the exposure in humans receiving the maximum recommended human daily dose of 25 mg. no-effect dose was not established.
