✦ Synopsis

An antipsychotic and two antidepressant drugs were studied for their effects on the visual aftereffects of tilt and movement in normal volunteers. Compared with placebo, haloperidol reduced the aftereffects. The antidepressant nomifensine enhanced the tilt but not the movement aftereffect, while maprotiline (another antidepressant) had no significant effect on either aftereffect. Control experiments showed that these changes were unlikely to have resulted from drug induced alterations in scanning eye movements during adaptation. The results are discussed with reference to possible dopaminergic influences on the visual system, and to some of the symptoms of schizophrenia.

Plasma concentrations of haloperidol and its reduced metabolite (reduced haloperidol) were investigated in cigarette smokers (N = 23) and nonsmokers (N = 27). Steady-state plasma concentrations were obtained 12 h post bedtime dose. Haloperidol and reduced haloperidol concentrations were determined b
