Most common adverse reactions (incidence >=3%) are throat irritation, viral respiratory infections, upper respiratory inflammation, cough, and musculoskeletal pain. (6.1)To report SUSPECTED ADVERSE REACTIONS, contact GlaxoSmithKline at 1-888-825-5249 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.. 6.1 Clinical Trials Experience. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.The safety data described below reflects exposure to VENTOLIN HFA in 248 subjects treated with VENTOLIN HFA in placebo-controlled clinical trials of to 12 weeks duration. The data from adults and adolescents is based upon clinical trials in which 202 subjects with asthma aged 12 years and older were treated with VENTOLIN HFA inhalations times daily for 12 weeks duration. The adult/adolescent population was 92 female, 110 male and 163 white, 19 black, 18 Hispanic, other. The data from pediatric subjects are based upon clinical trial in which 46 subjects with asthma aged to 11 years were treated with VENTOLIN HFA inhalations times daily for weeks duration. The population was 21 female, 25 male and 25 white, 17 black, Hispanic, other.Adult and Adolescent Subjects Aged 12 Years and OlderThe two 12-week, randomized, double-blind trials in 610 adult and adolescent subjects with asthma that compared VENTOLIN HFA, CFC 11/12-propelled albuterol inhaler, and an HFA-134a placebo inhaler. Overall, the incidence and nature of the adverse reactions reported for VENTOLIN HFA and CFC 11/12-propelled albuterol inhaler were comparable. Table lists the incidence of all adverse reactions (whether considered by the investigator to be related or unrelated to drug) from these trials that occurred at rate of >=3% in the group treated with VENTOLIN HFA and more frequently in the group treated with VENTOLIN HFA than in the HFA-134a placebo inhaler group.

Palpitations and dizziness have also been observed with VENTOLIN HFA.Pediatric Subjects Aged to 11 YearsResults from the 2-week clinical trial in pediatric subjects with asthma aged to 11 years showed that this pediatric population had an adverse reaction profile similar to that of the adult and adolescent populations.Three trials have been conducted to evaluate the safety and efficacy of VENTOLIN HFA in subjects between birth and years of age. The results of these trials did not establish the efficacy of VENTOLIN HFA in this age group [see Use in Specific Populations (8.4)]. Since the efficacy of VENTOLIN HFA has not been demonstrated in children between birth and 48 months of age, the safety of VENTOLIN HFA in this age group cannot be established. However, the safety profile observed in the pediatric population younger than years was comparable to that observed in the older pediatric subjects and in adults and adolescents. Where adverse reaction incidence rates were greater in subjects younger than years compared with older subjects, the higher incidence rates were noted in all treatment arms, including placebo. These adverse reactions included upper respiratory tract infection, nasopharyngitis, pyrexia, and tachycardia.. Throat irritation. Upper respiratory inflammation. Viral respiratory infections. Cough. Musculoskeletal pain. 6.2 Postmarketing Experience. In addition to adverse reactions reported from clinical trials, the following adverse reactions have been identified during postapproval use of albuterol sulfate. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure. These events have been chosen for inclusion due to either their seriousness, frequency of reporting, or causal connection to albuterol or combination of these factors.Cases of paradoxical bronchospasm, hoarseness, arrhythmias (including atrial fibrillation, supraventricular tachycardia), and hypersensitivity reactions (including urticaria, angioedema, rash) have been reported after the use of VENTOLIN HFA.In addition, albuterol, like other sympathomimetic agents, can cause adverse reactions such as hypokalemia, hypertension, peripheral vasodilatation, angina, tremor, central nervous system stimulation, hyperactivity, sleeplessness, headache, muscle cramps, drying or irritation of the oropharynx, and metabolic acidosis.

ANIMAL PHARMACOLOGY & OR TOXICOLOGY SECTION.


13.2 Animal Toxicology and/or Pharmacology. Intravenous studies in rats with albuterol sulfate have demonstrated that albuterol crosses the blood-brain barrier and reaches brain concentrations amounting to approximately 5% of the plasma concentrations. In structures outside the blood-brain barrier (pineal and pituitary glands), albuterol concentrations were found to be 100 times those in the whole brain.Studies in laboratory animals (minipigs, rodents, and dogs) have demonstrated the occurrence of cardiac arrhythmias and sudden death (with histologic evidence of myocardial necrosis) when beta-agonists and methylxanthines are administered concurrently. The clinical relevance of these findings is unknown.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.


13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. In 2-year study in Sprague-Dawley rats, albuterol sulfate caused dose-related increase in the incidence of benign leiomyomas of the mesovarium at and above dietary doses of mg/kg (approximately 15 and times the MRHDID for adults and children, respectively, on mg/m2 basis). In another study this effect was blocked by the coadministration of propranolol, non-selective beta-adrenergic antagonist. In an 18-month study in CD-1 mice, albuterol sulfate showed no evidence of tumorigenicity at dietary doses of up to 500 mg/kg (approximately 1,900 and 740 times the MRHDID for adults and children, respectively, on mg/m2 basis). In 22-month study in Golden hamsters, albuterol sulfate showed no evidence of tumorigenicity at dietary doses of up to 50 mg/kg (approximately 250 and 100 times the MRHDID for adults and children, respectively, on mg/m2 basis). Albuterol sulfate was not mutagenic in the Ames test or mutation test in yeast. Albuterol sulfate was not clastogenic in human peripheral lymphocyte assay or in an AH1 strain mouse micronucleus assay.Fertility and reproductive performance in rats demonstrated no evidence of impaired fertility at oral doses up to 50 mg/kg (approximately 380 times the MRHDID for adults on mg/m2 basis).

CLINICAL PHARMACOLOGY SECTION.


12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. In vitro studies and in vivo pharmacologic studies have demonstrated that albuterol has preferential effect on beta2-adrenergic receptors compared with isoproterenol. Although beta2-adrenoceptors are the predominant adrenergic receptors in bronchial smooth muscle and beta1-adrenoceptors are the predominant receptors in the heart, there are also beta2-adrenoceptors in the human heart comprising 10% to 50% of the total beta-adrenoceptors. The precise function of these receptors has not been established, but their presence raises the possibility that even selective beta2-agonists may have cardiac effects.Activation of beta2-adrenergic receptors on airway smooth muscle leads to the activation of adenyl cyclase and to an increase in the intracellular concentration of cyclic-3,5-adenosine monophosphate (cyclic AMP). This increase of cyclic AMP leads to the activation of protein kinase A, which inhibits the phosphorylation of myosin and lowers intracellular ionic calcium concentrations, resulting in relaxation. Albuterol relaxes the smooth muscles of all airways, from the trachea to the terminal bronchioles. Albuterol acts as functional antagonist to relax the airway irrespective of the spasmogen involved, thus protecting against all bronchoconstrictor challenges. Increased cyclic AMP concentrations are also associated with the inhibition of release of mediators from mast cells in the airway.Albuterol has been shown in most controlled clinical trials to have more effect on the respiratory tract, in the form of bronchial smooth muscle relaxation, than isoproterenol at comparable doses while producing fewer cardiovascular effects. Controlled clinical studies and other clinical experience have shown that inhaled albuterol, like other beta-adrenergic agonist drugs, can produce significant cardiovascular effect in some patients, as measured by pulse rate, blood pressure, symptoms, and/or electrocardiographic changes [see Warnings and Precautions (5.4)].. 12.3 Pharmacokinetics. The systemic levels of albuterol are low after inhalation of recommended doses. trial conducted in 12 healthy male and female subjects using higher dose (1,080 mcg of albuterol base) showed that mean peak plasma concentrations of approximately ng/mL occurred after dosing when albuterol was delivered using propellant HFA-134a. The mean time to peak concentrations (Tmax) was delayed after administration of VENTOLIN HFA (Tmax 0.42 hours) as compared with CFC-propelled albuterol inhaler (Tmax 0.17 hours). Apparent terminal plasma half-life of albuterol is approximately 4.6 hours. No further pharmacokinetic trials for VENTOLIN HFA were conducted in neonates, children, or elderly subjects.

CLINICAL STUDIES SECTION.


14 CLINICAL STUDIES. 14.1 Bronchospasm Associated with Asthma. Adult and Adolescent Subjects Aged 12 Years and OlderThe efficacy of VENTOLIN HFA was evaluated in two 12-week, randomized, double-blind, placebo-controlled trials in subjects aged 12 years and older with mild to moderate asthma. These trials included total of 610 subjects (323 males, 287 females). In each trial, subjects received inhalations of VENTOLIN HFA, CFC 11/12-propelled albuterol, or HFA-134a placebo times daily for 12 weeks duration. Subjects taking the HFA-134a placebo inhaler also took VENTOLIN HFA for asthma symptom relief on an as-needed basis. Some subjects who participated in these clinical trials were using concomitant inhaled steroid therapy. Efficacy was assessed by serial forced expiratory volume in second (FEV1). In each of these trials, inhalations of VENTOLIN HFA produced significantly greater improvement in FEV1 over the pretreatment value than placebo. Results from the clinical trials are described below.In 12-week, randomized, double-blind trial, VENTOLIN HFA (101 subjects) was compared with CFC 11/12-propelled albuterol (99 subjects) and an HFA-134a placebo inhaler (97 subjects) in adolescent and adult subjects aged 12 to 76 years with mild to moderate asthma. Serial FEV1 measurements [shown below as percent change from test-day baseline at Day (n 297) and at Week 12 (n 249)] demonstrated that inhalations of VENTOLIN HFA produced significantly greater improvement in FEV1 over the pretreatment value than placebo.FEV1 as Percent Change from Predose in Large, 12-Week Clinical TrialDay 1Week 12In the responder population (>=15% increase in FEV1 within 30 minutes postdose) treated with VENTOLIN HFA, the mean time to onset of 15% increase in FEV1 over the pretreatment value was 5.4 minutes, and the mean time to peak effect was 56 minutes. The mean duration of effect as measured by 15% increase in FEV1 over the pretreatment value was approximately hours. In some subjects, duration of effect was as long as hours.The second 12-week randomized, double-blind trial was conducted to evaluate the efficacy and safety of switching subjects from CFC 11/12-propelled albuterol to VENTOLIN HFA. During the 3-week run-in phase of the trial, all subjects received CFC 11/12-propelled albuterol. During the double-blind treatment phase, VENTOLIN HFA (91 subjects) was compared to CFC 11/12-propelled albuterol (100 subjects) and an HFA-134a placebo inhaler (95 subjects) in adult and adolescent subjects with mild to moderate asthma. Serial FEV1 measurements demonstrated that inhalations of VENTOLIN HFA produced significantly greater improvement in pulmonary function than placebo. The switching from CFC 11/12-propelled albuterol inhaler to VENTOLIN HFA did not reveal any clinically significant changes in the efficacy profile.In the adult trials, the efficacy results from VENTOLIN HFA were significantly greater than placebo and were clinically comparable to those achieved with CFC 11/12-propelled albuterol, although small numerical differences in mean FEV1 response and other measures were observed. Physicians should recognize that individual responses to beta-adrenergic agonists administered via different propellants may vary and that equivalent responses in individual patients should not be assumed.Pediatric Subjects Aged to 11 YearsThe efficacy of VENTOLIN HFA was evaluated in one 2-week, randomized, double-blind, placebo-controlled trial in 135 pediatric subjects aged to 11 years with mild to moderate asthma. In this trial, subjects received VENTOLIN HFA, CFC 11/12-propelled albuterol, or HFA-134a placebo. Serial pulmonary function measurements demonstrated that inhalations of VENTOLIN HFA produced significantly greater improvement in pulmonary function than placebo and that there were no significant differences between the groups treated with VENTOLIN HFA and CFC 11/12-propelled albuterol. In the responder population treated with VENTOLIN HFA, the mean time to onset of 15% increase in peak expiratory flow rate (PEFR) over the pretreatment value was 7.8 minutes, and the mean time to peak effect was approximately 90 minutes. The mean duration of effect as measured by 15% increase in PEFR over the pretreatment value was greater than hours. In some subjects, duration of effect was as long as hours.. FEV1 as Percent Change from Predose in Large, 12-Week Clinical Trial Day 1. FEV1 as Percent Change from Predose in Large, 12-Week Clinical Trial Week 12. 14.2 Exercise-Induced Bronchospasm. One controlled clinical trial in adult subjects with asthma (N 24) demonstrated that inhalations of VENTOLIN HFA taken approximately 30 minutes prior to exercise significantly prevented exercise-induced bronchospasm (as measured by maximum percentage fall in FEV1 following exercise) compared with an HFA-134a placebo inhaler. In addition, VENTOLIN HFA was shown to be clinically comparable to CFC 11/12-propelled albuterol inhaler for this indication.

DRUG INTERACTIONS SECTION.


7 DRUG INTERACTIONS. Other short-acting sympathomimetic aerosol bronchodilators should not be used concomitantly with albuterol. If additional adrenergic drugs are to be administered by any route, they should be used with caution to avoid deleterious cardiovascular effects.. oBeta-blockers: Use with caution. May block bronchodilatory effects of beta-agonists and produce severe bronchospasm. (7.1)oDiuretics: Use with caution. Electrocardiographic changes and/or hypokalemia associated with non-potassium-sparing diuretics may worsen with concomitant beta-agonists. (7.2)oDigoxin: May decrease serum digoxin levels. Consider monitoring digoxin levels. (7.3)oMonoamine oxidase inhibitors and tricyclic antidepressants: Use with extreme caution. May potentiate effect of albuterol on vascular system. (7.4). oBeta-blockers: Use with caution. May block bronchodilatory effects of beta-agonists and produce severe bronchospasm. (7.1). oDiuretics: Use with caution. Electrocardiographic changes and/or hypokalemia associated with non-potassium-sparing diuretics may worsen with concomitant beta-agonists. (7.2). oDigoxin: May decrease serum digoxin levels. Consider monitoring digoxin levels. (7.3). oMonoamine oxidase inhibitors and tricyclic antidepressants: Use with extreme caution. May potentiate effect of albuterol on vascular system. (7.4). 7.1 Beta-Adrenergic Receptor Blocking Agents. Beta-blockers not only block the pulmonary effect of beta-agonists, such as VENTOLIN HFA, but may also produce severe bronchospasm in patients with asthma. Therefore, patients with asthma should not normally be treated with beta-blockers. However, under certain circumstances, there may be no acceptable alternatives to the use of beta-adrenergic blocking agents for these patients; cardioselective beta-blockers could be considered, although they should be administered with caution.. 7.2 Non-Potassium-Sparing Diuretics. The ECG changes and/or hypokalemia that may result from the administration of non-potassium-sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the coadministration of VENTOLIN HFA with non-potassium-sparing diuretics.. 7.3 Digoxin. Mean decreases of 16% to 22% in serum digoxin levels were demonstrated after single-dose intravenous and oral administration of albuterol, respectively, to normal volunteers who had received digoxin for 10 days. The clinical relevance of these findings for patients with obstructive airway disease who are receiving inhaled albuterol and digoxin on chronic basis is unclear. Nevertheless, it would be prudent to carefully evaluate the serum digoxin levels in patients who are currently receiving digoxin and albuterol.. 7.4 Monoamine Oxidase Inhibitors and Tricyclic Antidepressants. VENTOLIN HFA should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within weeks of discontinuation of such agents, because the action of albuterol on the vascular system may be potentiated.

GERIATRIC USE SECTION.


8.5 Geriatric Use. Clinical trials of VENTOLIN HFA did not include sufficient numbers of subjects aged 65 years and older to determine whether older subjects respond differently than younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

LACTATION SECTION.


8.2 Lactation Risk SummaryThere are no available data on the presence of albuterol or the components of VENTOLIN HFA in human milk, the effects on the breastfed child, or the effects on milk production. However, plasma levels of albuterol after inhaled therapeutic doses are low in humans, and if present in breast milk, are likely to be correspondingly low [see Clinical Pharmacology (12.3)]. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for VENTOLIN HFA and any potential adverse effects on the breastfed child from VENTOLIN HFA or from the underlying maternal condition.

MECHANISM OF ACTION SECTION.


12.1 Mechanism of Action. In vitro studies and in vivo pharmacologic studies have demonstrated that albuterol has preferential effect on beta2-adrenergic receptors compared with isoproterenol. Although beta2-adrenoceptors are the predominant adrenergic receptors in bronchial smooth muscle and beta1-adrenoceptors are the predominant receptors in the heart, there are also beta2-adrenoceptors in the human heart comprising 10% to 50% of the total beta-adrenoceptors. The precise function of these receptors has not been established, but their presence raises the possibility that even selective beta2-agonists may have cardiac effects.Activation of beta2-adrenergic receptors on airway smooth muscle leads to the activation of adenyl cyclase and to an increase in the intracellular concentration of cyclic-3,5-adenosine monophosphate (cyclic AMP). This increase of cyclic AMP leads to the activation of protein kinase A, which inhibits the phosphorylation of myosin and lowers intracellular ionic calcium concentrations, resulting in relaxation. Albuterol relaxes the smooth muscles of all airways, from the trachea to the terminal bronchioles. Albuterol acts as functional antagonist to relax the airway irrespective of the spasmogen involved, thus protecting against all bronchoconstrictor challenges. Increased cyclic AMP concentrations are also associated with the inhibition of release of mediators from mast cells in the airway.Albuterol has been shown in most controlled clinical trials to have more effect on the respiratory tract, in the form of bronchial smooth muscle relaxation, than isoproterenol at comparable doses while producing fewer cardiovascular effects. Controlled clinical studies and other clinical experience have shown that inhaled albuterol, like other beta-adrenergic agonist drugs, can produce significant cardiovascular effect in some patients, as measured by pulse rate, blood pressure, symptoms, and/or electrocardiographic changes [see Warnings and Precautions (5.4)].

NONCLINICAL TOXICOLOGY SECTION.


13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. In 2-year study in Sprague-Dawley rats, albuterol sulfate caused dose-related increase in the incidence of benign leiomyomas of the mesovarium at and above dietary doses of mg/kg (approximately 15 and times the MRHDID for adults and children, respectively, on mg/m2 basis). In another study this effect was blocked by the coadministration of propranolol, non-selective beta-adrenergic antagonist. In an 18-month study in CD-1 mice, albuterol sulfate showed no evidence of tumorigenicity at dietary doses of up to 500 mg/kg (approximately 1,900 and 740 times the MRHDID for adults and children, respectively, on mg/m2 basis). In 22-month study in Golden hamsters, albuterol sulfate showed no evidence of tumorigenicity at dietary doses of up to 50 mg/kg (approximately 250 and 100 times the MRHDID for adults and children, respectively, on mg/m2 basis). Albuterol sulfate was not mutagenic in the Ames test or mutation test in yeast. Albuterol sulfate was not clastogenic in human peripheral lymphocyte assay or in an AH1 strain mouse micronucleus assay.Fertility and reproductive performance in rats demonstrated no evidence of impaired fertility at oral doses up to 50 mg/kg (approximately 380 times the MRHDID for adults on mg/m2 basis).. 13.2 Animal Toxicology and/or Pharmacology. Intravenous studies in rats with albuterol sulfate have demonstrated that albuterol crosses the blood-brain barrier and reaches brain concentrations amounting to approximately 5% of the plasma concentrations. In structures outside the blood-brain barrier (pineal and pituitary glands), albuterol concentrations were found to be 100 times those in the whole brain.Studies in laboratory animals (minipigs, rodents, and dogs) have demonstrated the occurrence of cardiac arrhythmias and sudden death (with histologic evidence of myocardial necrosis) when beta-agonists and methylxanthines are administered concurrently. The clinical relevance of these findings is unknown.

OVERDOSAGE SECTION.


10 OVERDOSAGE. The expected signs and symptoms with overdosage of albuterol are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of any of the signs and symptoms of beta-adrenergic stimulation (e.g., seizures, angina, hypertension or hypotension, tachycardia with rates up to 200 beats/min, arrhythmias, nervousness, headache, tremor, muscle cramps, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, insomnia, hyperglycemia, hypokalemia, metabolic acidosis).As with all inhaled sympathomimetic medicines, cardiac arrest and even death may be associated with an overdose of VENTOLIN HFA.Treatment consists of discontinuation of VENTOLIN HFA together with appropriate symptomatic therapy. The judicious use of cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. There is insufficient evidence to determine if dialysis is beneficial for overdosage of VENTOLIN HFA.

PEDIATRIC USE SECTION.


8.4 Pediatric Use. The safety and effectiveness of VENTOLIN HFA for treatment or prevention of bronchospasm and for prevention of exercised-induced bronchospasm in pediatric patients aged years and older have been established. Use of VENTOLIN HFA for this indication is supported by evidence from adequate and well-controlled studies of two 12-week clinical trials in subjects aged 12 years and older with asthma and one 2-week clinical trial in subjects aged to 11 years with asthma [see Adverse Reactions (6.1), Clinical Studies (14.1)]. The safety and effectiveness of VENTOLIN HFA in pediatric patients younger than years have not been established. Three trials have been conducted to evaluate the safety and efficacy of VENTOLIN HFA in subjects younger than years and the findings are described below.Two 4-week randomized, double-blind, placebo-controlled trials were conducted in 163 pediatric subjects aged from birth to 48 months with symptoms of bronchospasm associated with obstructive airway disease (presenting symptoms included: wheeze, cough, dyspnea, or chest tightness). VENTOLIN HFA or placebo HFA was delivered with either an AeroChamber Plus Valved Holding Chamber or an Optichamber Valved Holding Chamber with mask times daily. In one trial, VENTOLIN HFA 90 mcg (n 26), VENTOLIN HFA 180 mcg (n 25), and placebo HFA (n 26) were administered to children aged between 24 and 48 months. In the second trial, VENTOLIN HFA 90 mcg (n 29), VENTOLIN HFA 180 mcg (n 29), and placebo HFA (n 28) were administered to children aged between birth and 24 months. Over the 4-week treatment period, there were no treatment differences in asthma symptom scores between the groups receiving VENTOLIN HFA 90 mcg, VENTOLIN HFA 180 mcg, and placebo in either trial.In third trial, VENTOLIN HFA was evaluated in 87 pediatric subjects younger than 24 months for the treatment of acute wheezing. VENTOLIN HFA was delivered with an AeroChamber Plus Valved Holding Chamber in this trial. There were no significant differences in asthma symptom scores and mean change from baseline in an asthma symptom score between VENTOLIN HFA 180 mcg and VENTOLIN HFA 360 mcg.In vitro dose characterization studies were performed to evaluate the delivery of VENTOLIN HFA via holding chambers with attached masks. The studies were conducted with different holding chambers with masks (small and medium size). The in vitro study data when simulating patient breathing suggest that the dose of VENTOLIN HFA presented for inhalation via valved holding chamber with mask will be comparable to the dose delivered in adults without spacer and mask per kilogram of body weight (Table 2). However, clinical trials in children younger than years described above suggest that either the optimal dose of VENTOLIN HFA has not been defined in this age group or VENTOLIN HFA is not effective in this age group. The safety and effectiveness of VENTOLIN HFA administered with or without spacer device in children younger than years have not been demonstrated.Table 2.

Ranges correspond to the average of the 50th percentile weight for boys and girls at the ages indicated.b single inhalation of Ventolin HFA in 70-kg adult without use of valved holding chamber and mask delivers approximately 90 mcg, or 1.3 mcg/kg.AgeMaskFlow Rate (L/min)Holding Time (seconds)Mean Medication Delivery through AeroChamber Plus (mcg/actuation)Body Weight 50th Percentile (kg)a Medication Delivered per Actuation (mcg/kg)b to 12 MonthsSmall4.9018.27.5-9.91.8-2.4219.82.0-2.6513.81.4-1.81015.41.6-2.12 to YearsSmall8.0017.812.3-18.01.0-1.4216.00.9-1.3516.30.9-1.31018.31.0-1.52 to YearsMedium8.0021.112.3-18.01.2-1.7215.30.8-1.2518.31.0-1.51018.21.0-1.5>5 YearsMedium12.0026.818.01.5220.91.2519.61.11020.31.1.

PREGNANCY SECTION.


8.1 Pregnancy. Pregnancy Exposure RegistryThere is pregnancy exposure registry that monitors pregnancy outcomes in women exposed to asthma medications during pregnancy. For more information, contact the MotherToBaby Pregnancy Studies conducted by the Organization of Teratology Information Specialists at 1-877-311-8972 or visit https://mothertobaby.org/ongoing-study/asthma/.Risk SummaryThere are no randomized clinical studies of use of albuterol sulfate during pregnancy. Available data from epidemiological studies and postmarketing case reports of pregnancy outcomes following inhaled albuterol use do not consistently demonstrate risk of major birth defects or miscarriage. There are, however, clinical considerations in pregnant women with asthma. (See Clinical Considerations.) Administration of VENTOLIN HFA to mice and rabbits during the period of organogenesis revealed evidence of adverse developmental outcomes (cleft palate in mice, delayed ossification in rabbits) at less than the maximum recommended human daily inhaled dose (MRHDID). (See Data.) The estimated background risk of major birth defects and miscarriage for the indicated population(s) is unknown. In the U.S. general population, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.Clinical ConsiderationsDisease-Associated Maternal and/or Embryofetal Risk: In women with poorly or moderately controlled asthma, there is an increased risk of several perinatal adverse outcomes such as preeclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate. Pregnant women with asthma should be closely monitored and medication adjusted as necessary to maintain optimal asthma control.Labor or Delivery: Because of the potential for beta-agonist interference with uterine contractility, use of VENTOLIN HFA during labor should be restricted to those patients in whom the benefits clearly outweigh the risk. VENTOLIN HFA has not been approved for the management of pre-term labor. Serious adverse reactions, including pulmonary edema, have been reported during or following treatment of premature labor with beta2-agonists, including albuterol.DataHuman Data: While available studies cannot definitively establish the absence of risk, published data from epidemiological studies and case reports have not consistently demonstrated an association with use of VENTOLIN HFA during pregnancy and major birth defects, specific birth defects, or miscarriage. The available studies have methodologic limitations, including inconsistent comparator groups, definitions of outcomes, and assessment of disease impact.Animal Data: In study in pregnant mice, subcutaneously administered albuterol sulfate produced cleft palate formation in of 111 (4.5%) fetuses at an exposure less than the MRHDID for adults (on mg/m2 basis at maternal dose of 0.25 mg/kg) and in 10 of 108 (9.3%) fetuses at approximately times the MRHDID (on mg/m2 basis at maternal dose of 2.5 mg/kg). Cleft palate also occurred in 22 of 72 (30.5%) fetuses from females treated subcutaneously with isoproterenol, another beta2-agonist. In study in pregnant rabbits, orally administered albuterol sulfate produced cranioschisis in of 19 fetuses (37%) at approximately 750 times the MRHDID (on mg/m2 basis at maternal dose of 50 mg/kg).In study in pregnant rabbits, an albuterol/HFA-134a formulation administered by inhalation produced enlargement of the frontal portion of the fetal fontanelles at approximately one third of the MRHDID on mg/m2 basis.A study in which pregnant rats were dosed with radiolabeled albuterol sulfate demonstrated that drug-related material is transferred from the maternal circulation to the fetus.

USE IN SPECIFIC POPULATIONS SECTION.


8 USE IN SPECIFIC POPULATIONS. 8.1 Pregnancy. Pregnancy Exposure RegistryThere is pregnancy exposure registry that monitors pregnancy outcomes in women exposed to asthma medications during pregnancy. For more information, contact the MotherToBaby Pregnancy Studies conducted by the Organization of Teratology Information Specialists at 1-877-311-8972 or visit https://mothertobaby.org/ongoing-study/asthma/.Risk SummaryThere are no randomized clinical studies of use of albuterol sulfate during pregnancy. Available data from epidemiological studies and postmarketing case reports of pregnancy outcomes following inhaled albuterol use do not consistently demonstrate risk of major birth defects or miscarriage. There are, however, clinical considerations in pregnant women with asthma. (See Clinical Considerations.) Administration of VENTOLIN HFA to mice and rabbits during the period of organogenesis revealed evidence of adverse developmental outcomes (cleft palate in mice, delayed ossification in rabbits) at less than the maximum recommended human daily inhaled dose (MRHDID). (See Data.) The estimated background risk of major birth defects and miscarriage for the indicated population(s) is unknown. In the U.S. general population, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.Clinical ConsiderationsDisease-Associated Maternal and/or Embryofetal Risk: In women with poorly or moderately controlled asthma, there is an increased risk of several perinatal adverse outcomes such as preeclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate. Pregnant women with asthma should be closely monitored and medication adjusted as necessary to maintain optimal asthma control.Labor or Delivery: Because of the potential for beta-agonist interference with uterine contractility, use of VENTOLIN HFA during labor should be restricted to those patients in whom the benefits clearly outweigh the risk. VENTOLIN HFA has not been approved for the management of pre-term labor. Serious adverse reactions, including pulmonary edema, have been reported during or following treatment of premature labor with beta2-agonists, including albuterol.DataHuman Data: While available studies cannot definitively establish the absence of risk, published data from epidemiological studies and case reports have not consistently demonstrated an association with use of VENTOLIN HFA during pregnancy and major birth defects, specific birth defects, or miscarriage. The available studies have methodologic limitations, including inconsistent comparator groups, definitions of outcomes, and assessment of disease impact.Animal Data: In study in pregnant mice, subcutaneously administered albuterol sulfate produced cleft palate formation in of 111 (4.5%) fetuses at an exposure less than the MRHDID for adults (on mg/m2 basis at maternal dose of 0.25 mg/kg) and in 10 of 108 (9.3%) fetuses at approximately times the MRHDID (on mg/m2 basis at maternal dose of 2.5 mg/kg). Cleft palate also occurred in 22 of 72 (30.5%) fetuses from females treated subcutaneously with isoproterenol, another beta2-agonist. In study in pregnant rabbits, orally administered albuterol sulfate produced cranioschisis in of 19 fetuses (37%) at approximately 750 times the MRHDID (on mg/m2 basis at maternal dose of 50 mg/kg).In study in pregnant rabbits, an albuterol/HFA-134a formulation administered by inhalation produced enlargement of the frontal portion of the fetal fontanelles at approximately one third of the MRHDID on mg/m2 basis.A study in which pregnant rats were dosed with radiolabeled albuterol sulfate demonstrated that drug-related material is transferred from the maternal circulation to the fetus.. 8.2 Lactation Risk SummaryThere are no available data on the presence of albuterol or the components of VENTOLIN HFA in human milk, the effects on the breastfed child, or the effects on milk production. However, plasma levels of albuterol after inhaled therapeutic doses are low in humans, and if present in breast milk, are likely to be correspondingly low [see Clinical Pharmacology (12.3)]. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for VENTOLIN HFA and any potential adverse effects on the breastfed child from VENTOLIN HFA or from the underlying maternal condition.. 8.4 Pediatric Use. The safety and effectiveness of VENTOLIN HFA for treatment or prevention of bronchospasm and for prevention of exercised-induced bronchospasm in pediatric patients aged years and older have been established. Use of VENTOLIN HFA for this indication is supported by evidence from adequate and well-controlled studies of two 12-week clinical trials in subjects aged 12 years and older with asthma and one 2-week clinical trial in subjects aged to 11 years with asthma [see Adverse Reactions (6.1), Clinical Studies (14.1)]. The safety and effectiveness of VENTOLIN HFA in pediatric patients younger than years have not been established. Three trials have been conducted to evaluate the safety and efficacy of VENTOLIN HFA in subjects younger than years and the findings are described below.Two 4-week randomized, double-blind, placebo-controlled trials were conducted in 163 pediatric subjects aged from birth to 48 months with symptoms of bronchospasm associated with obstructive airway disease (presenting symptoms included: wheeze, cough, dyspnea, or chest tightness). VENTOLIN HFA or placebo HFA was delivered with either an AeroChamber Plus Valved Holding Chamber or an Optichamber Valved Holding Chamber with mask times daily. In one trial, VENTOLIN HFA 90 mcg (n 26), VENTOLIN HFA 180 mcg (n 25), and placebo HFA (n 26) were administered to children aged between 24 and 48 months. In the second trial, VENTOLIN HFA 90 mcg (n 29), VENTOLIN HFA 180 mcg (n 29), and placebo HFA (n 28) were administered to children aged between birth and 24 months. Over the 4-week treatment period, there were no treatment differences in asthma symptom scores between the groups receiving VENTOLIN HFA 90 mcg, VENTOLIN HFA 180 mcg, and placebo in either trial.In third trial, VENTOLIN HFA was evaluated in 87 pediatric subjects younger than 24 months for the treatment of acute wheezing. VENTOLIN HFA was delivered with an AeroChamber Plus Valved Holding Chamber in this trial. There were no significant differences in asthma symptom scores and mean change from baseline in an asthma symptom score between VENTOLIN HFA 180 mcg and VENTOLIN HFA 360 mcg.In vitro dose characterization studies were performed to evaluate the delivery of VENTOLIN HFA via holding chambers with attached masks. The studies were conducted with different holding chambers with masks (small and medium size). The in vitro study data when simulating patient breathing suggest that the dose of VENTOLIN HFA presented for inhalation via valved holding chamber with mask will be comparable to the dose delivered in adults without spacer and mask per kilogram of body weight (Table 2). However, clinical trials in children younger than years described above suggest that either the optimal dose of VENTOLIN HFA has not been defined in this age group or VENTOLIN HFA is not effective in this age group. The safety and effectiveness of VENTOLIN HFA administered with or without spacer device in children younger than years have not been demonstrated.Table 2.

Ranges correspond to the average of the 50th percentile weight for boys and girls at the ages indicated.b single inhalation of Ventolin HFA in 70-kg adult without use of valved holding chamber and mask delivers approximately 90 mcg, or 1.3 mcg/kg.AgeMaskFlow Rate (L/min)Holding Time (seconds)Mean Medication Delivery through AeroChamber Plus (mcg/actuation)Body Weight 50th Percentile (kg)a Medication Delivered per Actuation (mcg/kg)b to 12 MonthsSmall4.9018.27.5-9.91.8-2.4219.82.0-2.6513.81.4-1.81015.41.6-2.12 to YearsSmall8.0017.812.3-18.01.0-1.4216.00.9-1.3516.30.9-1.31018.31.0-1.52 to YearsMedium8.0021.112.3-18.01.2-1.7215.30.8-1.2518.31.0-1.51018.21.0-1.5>5 YearsMedium12.0026.818.01.5220.91.2519.61.11020.31.1. 8.5 Geriatric Use. Clinical trials of VENTOLIN HFA did not include sufficient numbers of subjects aged 65 years and older to determine whether older subjects respond differently than younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

WARNINGS AND PRECAUTIONS SECTION.


5 WARNINGS AND PRECAUTIONS. oLife-threatening paradoxical bronchospasm may occur. Discontinue VENTOLIN HFA immediately and institute alternative therapy. (5.1)oNeed for more doses of VENTOLIN HFA than usual may be sign of deterioration of asthma and requires reevaluation of treatment. (5.2)oVENTOLIN HFA is not substitute for corticosteroids. (5.3)oCardiovascular effects may occur. Use with caution in patients sensitive to sympathomimetic drugs and patients with cardiovascular or convulsive disorders. (5.4, 5.7)oExcessive use may be fatal. Do not exceed recommended dose. (5.5)oImmediate hypersensitivity reactions may occur. Discontinue VENTOLIN HFA immediately. (5.6)oHypokalemia and changes in blood glucose may occur. (5.7, 5.8). oLife-threatening paradoxical bronchospasm may occur. Discontinue VENTOLIN HFA immediately and institute alternative therapy. (5.1). oNeed for more doses of VENTOLIN HFA than usual may be sign of deterioration of asthma and requires reevaluation of treatment. (5.2). oVENTOLIN HFA is not substitute for corticosteroids. (5.3). oCardiovascular effects may occur. Use with caution in patients sensitive to sympathomimetic drugs and patients with cardiovascular or convulsive disorders. (5.4, 5.7). oExcessive use may be fatal. Do not exceed recommended dose. (5.5). oImmediate hypersensitivity reactions may occur. Discontinue VENTOLIN HFA immediately. (5.6). oHypokalemia and changes in blood glucose may occur. (5.7, 5.8). 5.1 Paradoxical Bronchospasm. VENTOLIN HFA can produce paradoxical bronchospasm, which may be life threatening. If paradoxical bronchospasm occurs following dosing with VENTOLIN HFA, it should be discontinued immediately and alternative therapy should be instituted. It should be recognized that paradoxical bronchospasm, when associated with inhaled formulations, frequently occurs with the first use of new canister.. 5.2 Deterioration of Asthma. Asthma may deteriorate acutely over period of hours or chronically over several days or longer. If the patient needs more doses of VENTOLIN HFA than usual, this may be marker of destabilization of asthma and requires reevaluation of the patient and treatment regimen, giving special consideration to the possible need for anti-inflammatory treatment, e.g., corticosteroids.. 5.3 Use of Anti-inflammatory Agents. The use of beta-adrenergic agonist bronchodilators alone may not be adequate to control asthma in many patients. Early consideration should be given to adding anti-inflammatory agents, e.g., corticosteroids, to the therapeutic regimen.. 5.4 Cardiovascular Effects. VENTOLIN HFA, like all other beta2-adrenergic agonists, can produce clinically significant cardiovascular effects in some patients such as changes in pulse rate or blood pressure. If such effects occur, VENTOLIN HFA may need to be discontinued. In addition, beta-agonists have been reported to produce electrocardiogram (ECG) changes, such as flattening of the wave, prolongation of the QTc interval, and ST segment depression. The clinical relevance of these findings is unknown. Therefore, VENTOLIN HFA, like all other sympathomimetic amines, should be used with caution in patients with underlying cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.. 5.5 Do Not Exceed Recommended Dose. Fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs in patients with asthma. The exact cause of death is unknown, but cardiac arrest following an unexpected development of severe acute asthmatic crisis and subsequent hypoxia is suspected.. 5.6 Hypersensitivity Reactions, including Anaphylaxis. Immediate hypersensitivity reactions (e.g., urticaria, angioedema, rash, bronchospasm, hypotension), including anaphylaxis, may occur after administration of VENTOLIN HFA [see Contraindications (4)].. 5.7 Coexisting Conditions. VENTOLIN HFA, like other sympathomimetic amines, should be used with caution in patients with convulsive disorders, hyperthyroidism, or diabetes mellitus and in patients who are unusually responsive to sympathomimetic amines. Large doses of intravenous albuterol have been reported to aggravate preexisting diabetes mellitus and ketoacidosis.. 5.8 Hypokalemia. Beta-adrenergic agonist medicines may produce significant hypokalemia in some patients, possibly through intracellular shunting, which has the potential to produce adverse cardiovascular effects [see Clinical Pharmacology (12.1)]. The decrease in serum potassium is usually transient, not requiring supplementation.
