Haloperidol plasma and red blood cell levels and clinical antipsychotic response.
Two investigators have recently suggested therapeutic ranges for plasma haloperidol in the treatment of schizophrenia. An apparent optimal therapeutic range of red blood cell haloperidol as early as day 7 of the drug trial is described in this article. With continued treatment, an optimal plasma haloperidol range for response could be observed by day 14 of treatment. The previously described correlation between response at day 7 and plasma/red blood cell haloperidol ratio was confirmed but was found not to predict response at day 14 of drug treatment in this cohort of DSM-III schizophrenic patients.
