title: Elimination half-life and bioavailability of haloperidol in schizophrenic patients.
abstract: Haloperidol was administered orally to 6 male schizophrenic patients and intravenously to 3. Elimination half-life (t1/2 beta) and bioavailability (F) were calculated for both groups from haloperidol serum concentrations determined by gas-liquid chromatography. Mean (+/- SD) half-lives were 17.5 +/- 8.7 hours for oral administration and 15.1 +/- 2.5 hours for intravenous; bioavailability was 0.64 +/- 0.23. These values were comparable to those found in normal volunteers.
