Cogentine - General Information

A centrally active muscarinic antagonist that has been used in the symptomatic treatment of parkinson disease. Cogentine also inhibits the uptake of dopamine.


Pharmacology of Cogentine

Cogentine is an anticholinergic used in the symptomatic treatment of all etiologic groups of parkinsonism and drug induced extrapyramidal reactions (except tardive dyskinesia). Cogentine possesses both anticholinergic and antihistaminic effects, although only the former has been established as therapeutically significant in the management of parkinsonism. Cogentine's anticholinergic activity is about equal to that of atropine.


Cogentine for patients


Cogentine Interactions

Antipsychotic drugs such as phenothiazines or haloperidol; tricyclic antidepressants.


Cogentine Contraindications

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 Cogentine

Cogentine 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: Cogentine 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). Cogentine 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.
Avoid alcohol.
