Atosil - General Information

Atosil (or methixene) is a anticholinergic used as an anti-parkinson drug. [Wikipedia]

 

Pharmacology of Atosil

Atosil is a tertiary antimuscarinic with actions similar to those of atropine; it also has antihistaminic and direct antispasmodic properties. It is used for the symptomatic treatment of parkinsonism, including the alleviation of the extrapyramidal syndrome induced by other drugs such as phenothiazines, but, like other antimuscarinics, it is of no value against tardive dyskinesias. Atosil has been discontinued.

 

Additional information about Atosil

Atosil Indication: Used for the symptomatic treatment of parkinsonism.
Mechanism Of Action: Parkinsonism is thought to result from an imbalance between the excitatory (cholinergic) and inhibitory (dopaminergic) systems in the corpus striatum. The mechanism of action of centrally active anticholinergic drugs such as metixene is considered to relate to competitive antagonism of acetylcholine at cholinergic receptors in the corpus striatum, which then restores the balance.
