Increase in mouse brain dopamine content by baclofen: effects of apomorphine and neuroleptics

G Gianutsos et al. Psychopharmacology (Berl). .

Abstract

Baclofen, like gamma-butyrolactone, causes a dose-dependent increase in the concentration of dopamine in the mouse brain without affecting the content of norepinephrine. This increase is antagonized by apomorphine. Haloperidol but not pimozide counteracts this effect of apomorphine and dose-dependently enhances the increase in brain dopamine produced by baclofen. The results suggest that baclofen reduces impulse flow in dopaminergic neurons in a manner similar to that produced by gamma-butyrolactone.
