Cholinergic inhibition of methylphenidate-induced stereotypy: oxotremorine

Abstract

Lethality of orally administered oxotremorine for female mice required 250 times the dose that was effective for inhibiting methylphenidate-induced stereotypy. A number of lines of evidence indicate that increasing central cholinergic activity may be useful in various psychiatric syndromes and movement disorders. A relatively safe oral cholinomimetic would be clinically useful. Oxotremorine may be such an agent.
