Apo-Benztropine - General Information
A centrally active muscarinic antagonist that has been used in the symptomatic treatment of parkinson disease. Apo-Benztropine also inhibits the uptake of dopamine.
Pharmacology of Apo-Benztropine
Apo-Benztropine is an anticholinergic used in the symptomatic treatment of all etiologic groups of parkinsonism and drug induced extrapyramidal reactions (except tardive dyskinesia). Apo-Benztropine possesses both anticholinergic and antihistaminic effects, although only the former has been established as therapeutically significant in the management of parkinsonism. Apo-Benztropine's anticholinergic activity is about equal to that of atropine.
Apo-Benztropine for patients
Antipsychotic drugs such as phenothiazines or haloperidol; tricyclic antidepressants.
Hypersensitivity to any component of benztropine mesylate tablets. Because of its atropine-like side effects, this drug is contraindicated in children under three years of age and should be used with caution in older children.
Additional information about Apo-Benztropine
Apo-Benztropine Indication: For use as an adjunct in the therapy of all forms of parkinsonism and also for use in the control of extrapyramidal disorders due to neuroleptic drugs.
Mechanism Of Action: Apo-Benztropine is a selective M1 muscarinic acetylcholine receptor antagonist. It is able to discriminate between the M1 (cortical or neuronal) and the peripheral muscarinic subtypes (cardiac and glandular). Apo-Benztropine partially blocks cholinergic activity in the CNS, which is responsible for the symptoms of Parkinson's disease. It is also thought to increase the availability of dopamine, a brain chemical that is critical in the initiation and smooth control of voluntary muscle movement.
Drug Interactions: Donepezil Possible antagonism of action
Galantamine Possible antagonism of action
Haloperidol The anticholinergic increases the risk of psychosis and tardive dyskinesia
Rivastigmine Possible antagonism of action
Food Interactions: Take with food to reduce irritation.
