etho·pro·pa·zine hy·dro·chlo·ride (eth″o-proґpə-zēn) a phenothiazine derivative used as an antidyskinetic, believed to act by partially blocking central cholinergic receptors, so that cholinergic and dopaminergic activity in the basal ganglia is more balanced; used in the treatment of parkinsonism and for the control of drug-induced extrapyramidal reactions (except tardive dyskinesia); administered orally.
