[Effects of neuroleptics on liver function, the hematopoietic system, blood pressure and temperature regulation. Comparison of clozapine, perazine and haloperidol by evaluating medical records].

Abstract

The frequency of disturbances of the liver function, of leucopoiesis, blood pressure and temperature regulation under clozapine in comparison with perazine and haloperidol in 478 patients (partly being treated repeatedly) was investigated by means of case histories of the Psychiatric Clinic of Tübingen from October 1974 up to June 1978. Within the time of the investigation no case of jaundice arose, however non-symptomatic increases of the liver values could be observed. The three drugs did not differ in this respect. Within the time of the investigation no case of agranulocytosis was observed. Only one leucopenia under clozapine, one under perazine, and six under haloperidol occurred. Concerning cardio-vascular effects of the neuroleptic medication, in 4.1% of the patients under clozapine therapy, 4.3% under haloperidol therapy and 10.3% under perazine therapy hypotension could be observed. Under clozapine 15.2% of the patients showed a rise of temperature, under perazine 3.2% and under haloperidol 2.8% of the patients. 83.3% of cases with elevated temperature under clozapine occurred during the first two weeks of treatment.
