Disclaimer: Anticholium (R)(physostigmine salicylate) is not FDA approved, but is imported with foreign, non-U.S. labeling under temporary importation license to address supply shortage. Dosage Formsolution for injectionsolution for injection or infusionLabelCompositionPhysostigmine Salicylate Injection is available in mL ampules, each mL containing mg of Physostigmine Salicylate in vehicle composed of sodium metabisulfite 0.1%, benzyl alcohol 2.0% as preservative in Water for Injection.Anticholium (R)is available in mL ampules, each mL containing 0.4 mg physostigmine salicylate in vehicle composed of sodium edetate (Ph. Eur.), nitrogene and water for injection. IndicationsINDICATIONS AND USAGE:To reverse the effect upon the central nervous system, caused by clinical or toxic dosages of drugs capable of producing the anticholinergic syndrome Anticholium (R) is indicated for: 1. the use as an antidote and/or antagonist in case of intoxication with and/or overdose of:alcoholtropane alkaloids (hyoscyamine, atropine, scopolamine, as e.g. in brugmansia, datura, atropa belladonna)amanita pantherina and amanita muscariatricyclic antidepressants (amitriptyline, imipramine, trimipramine, clomipramine, doxepine)antiemetics/antihistamines (phenothiazine, thioridazine, chlorpromazine, promethazine, diphenhydramine, dimenhydrinate)neuroleptic drugs (especially butyrophenones)benzodiazepinestolterodine, oxybutynineamantadine, diphenhydraminebaclofen4-hydroxybutyric acid (GHB)inhalation anestheticsketamine3-quinuclidinyl benzilate2. the treatment of postoperative disorders:Central anticholinergic syndrome (CAS)Delayed postoperative awakeningShiveringContraindicationsPhysostigmine Salicylate Injection should not be used in the presence of asthma, gangrene, diabetes, cardiovascular disease, mechanical obstruction of the intestine or urogenital tract or any vagotonic state, and in patients receiving choline esters and depolarizing neuromuscular blocking agents (decamethonium, succinylcholine).For post-anesthesia, the concomitant use of atropine with physostigmine salicylate is not recommended, since the atropine antagonizes the action of physostigmine.Anticholium (R)should not be used in the presence of hypersensitivity to physostigmine salicylate, bronchial asthma, ulcers associated with tissue destruction (gangrene), coronary heart disease, constipation (mechanical obstipation), mechanical ischuria (urinary retention), hereditary form of muscle atrophy (myotonic dystrophy), closed traumatic brain injuries, intestinal obstruction, spasms in the urinary tract collection system, inactivation of nerve and muscle cells after administration of drugs to relax the muscles (depolarization block after depolarizing muscle relaxants), in case of intoxication due to irreversibly acting cholinesterase inhibitors (drugs used to treat dementia), intoxication with phosphoric acid esters or barbiturates. PrecautionsPRECAUTIONS:Because of the possibility of hypersensitivity in an occasional patient, atropine sulfate injection should always be at hand since it is an antagonist and antidote for physostigmine.Talk to your doctor before you are given Anticholium (R)if you suffer from diabetes mellitus, slowed heart rate (bradycardia), disturbances of the atrioventricular conduction system, Parkinsons disease or ulcerative colitis. Hypersensitivity reactions may occur after administration of this medicine. These reactions may vary individually and may also cause life-threatening conditions. It is recommended to have emergency medication and medical aids ready. risk/benefit analysis should be performed, and discontinuation of treatment should be considered.Acute cardiac arrest may be possible during treatment with tricyclic antidepressants; therefore, Anticholium (R)should only be considered as an antidote for this indication while the patient has continuous ECG monitoring. Interactions-Tell your doctor or pharmacist if you are taking/using, have recently taken/used or intend to take/use any other medicines.In case of simultaneous administration of other cholinesterase inhibitors (e.g. medicines for the treatment of dementia), caution should be exercised because of the potentiating effect. In intoxication with depolarizing muscle relaxants of the suxamethonium type, Anticholium (R)is contraindicated WarningsContains sodium bisulfite, sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in non-asthmatic people.If excessive symptoms of salivation, emesis, urination and defecation occur, the use of Physostigmine Salicylate Injection should be terminated. If excessive sweating or nausea occur, the dosage should be reduced.Intravenous administration should be at slow, controlled rate, no more than mg per minute (see dosage). Rapid administration can cause bradycardia, hypersalivation leading to respiratory difficulties and possible convulsions.An overdosage of Physostigmine Salicylate Injection can cause cholinergic crisis.Talk to your doctor before you are given Anticholium (R)if you suffer from diabetes mellitus, slowed heart rate (bradycardia), disturbances of the atrioventricular conduction system, Parkinsons disease or ulcerative colitis. Hypersensitivity reactions may occur after administration of this medicine. These reactions may vary individually and may also cause life-threatening conditions. It is recommended to have emergency medication and medical aids ready. risk/benefit analysis should be performed and discontinuation of treatment should be considered.Acute cardiac arrest may be possible during treatment with tricyclic antidepressants; therefore, Anticholium (R)should only be considered as an antidote for this indication while the patient has continuous ECG monitoring. Dosage and AdministrationPast Anesthesia Care: 0.5 to 1.0 mg intramuscularly or intravenously. INTRAVENOUS ADMINISTRATION SHOULD BE AT SLOW CONTROLLED RATE OF NO MORE THAN MG PER MINUTE. Dosage may be repeated at intervals of 10 to 30 minutes if desired patient response is not obtained.PEDIATRIC DOSAGE:Recommended dosage is 0.02 mg/kg; intramuscularly or by slow intravenous injection, no more than 0.5 mg per minute. If the toxic effects persist, and there is no sign of cholinergic effects, the dosage may be repeated at to 10 minute intervals until therapeutic effect is obtained or maximum of mg dosage is attained.IN ALL CASES OF POISONING, THE USUAL SUPPORTIVE MEASURES SHOULD BE UNDERTAKEN.Use in adults:For the treatment of postoperative awakening disorders:Slowly inject physostigmine intravenously at dose of 0.04 mg/kg bodyweight (approx. mg/min), the maximum individual dose is mg.In case of insufficient effect, give subsequent injections after to 20 minutes at the earliest, after positive evaluation of the effect of the first injection.In cases of intoxication:Adults: Slowly inject 0.04 mg/kg bodyweight (2 mg) of physostigmine salicylate intravenously and subsequently inject 1-4 mg every 20 minutes. Repeat the effective dose if the intoxication symptoms recur, also in the form of continuous infusion if deemed useful.Use in children and adolescents:In cases of intoxication: Infants: Start with low dose of 0.5 mg of physostigmine salicylate administered intravenously, repeat this dose every minutes up to the overall dose of mg, as long as the toxic, anticholinergic symptoms continue to persist, and no cholinergic symptoms occur.Method of administrationIntravenously slowly or as brief infusion in 50 ml physiological saline solution over 10-15 minutes. general criterion for adequate physostigmine dosing is the recognizable recovery of mental abilities and responsiveness (e.g. specifying name, address, date).OverdosageCan cause cholinergic crisis. Appropriate antidote is atropine sulfate.Intravenous administration of atropine up to normalization of the symptoms.Normally, half the amount of the administered physostigmine salicylate is sufficient. In case of intoxication, measures to prevent absorption are to be started immediately (such as gastric lavage, administration of medicinal charcoal and laxatives).The following information is intended for healthcare professionals:Overdose emergency measures, symptoms, antidotesIn cases of intoxication, measures to prevent absorption such as gastric lavage, administration of medicinal charcoal and laxatives are to be started immediately.An overdose of Anticholium (R)can cause bradycardia, hypersalivation, vomiting, and generalized tonic-clonic seizures. Patients should be closely monitored by ECG.Adverse ReactionsNausea, vomiting and salivation; can be offset by reducing dosage. Bradycardia and convulsions, if intravenous administration is too rapid. See DOSAGE AND ADMINISTRATION.Like all medicines, Anticholium (R)can cause side effects, although not everybody gets them. Usage in pregnancySafe use in pregnancy and lactation has not been established; therefore, use in pregnant women, nursing mothers or women who may become pregnant requires that possible benefits be weighed against possible hazards to mother and child.Pregnancy and breast-feedingPregnancy:There is no experience with the use of Anticholium (R)in pregnant women. Physostigmine, the active substance contained in Anticholium (R), passes into the placenta. Animal studies are insufficient with respect to effects on pregnancy, embryonal/foetal development, birth and postnatal development. The potential risk for humans is unknown. For this reason, Anticholium (R)may only be administered to pregnant women if deemed absolutely necessary by the attending doctor. Breast-feeding:There is no experience with the use of Anticholium (R)during breastfeeding. It is not known whether physostigmine, the active substance contained in Anticholium (R), is excreted in human breast milk. For this reason, Anticholium (R)may only be used during breastfeeding if deemed absolutely necessary by the attending doctor.
