title: [On the practice of clinical therapy with psychotropic drugs -- retrospective investigation of physicians prescribing practices in a psychiatric hospital (author's transl)].
abstract: 1. At the psychiatric hospital of the University of Munich physicians' practices in prescribing psychotropic drugs have been analyzed retrospectively for 1974. Case report of 2,100 patients from a total of 2,118 newly admitted inpatients in 1974 have been evaluated and various methods of analyzing data are compared. 2. 414 (19.7%) patients out of a total of 2100 have not been medicated by any drugs. On the average 2.7 psychotropic drugs/patient have been precribed in the remaining 1,186 patients (80.3%). 3. 37.4% of 4627 applications made have been allotted to neuroleptics. Clozapine has been found to be the drug most extensively used (37.4%). It was prescribed to 595 patients, followed by chloralhydrate (425 patients) and amitriptyline (374 patients). 4. Out of a total of 5373 prescriptions, 2,004 were allotted to a single substance and 3,369 to a combination of different drugs. With regard to combined medications, in 1,856 prescriptions two drugs were combined, in 1,015 three, in 404 four, in 70 five, in 18 six and finally in 6 prescriptions seven medications were applied to one patient. 5. Antidepressants and neuroleptics have been combined on the same patient in 768 prescriptions. As to neuroleptics most frequently clozapine and haloperidol have been prescribed together. 6. The mean time during which a defined combination of drugs was given continuously, never exceeded a quarter of the total time the individual had been admitted to the hospital. 7. It is evident that in clinical practice the combinations of psychotropic drugs are widely used. This pattern of psychopharmacological drug treatment is in conflict with the present accepted rules of psychotropic pharmacotherapy. Furthermore it is a remarkable result of the present studies that in therapeutical practice the single components of drug combinations are changed very often. Compounds with sedative effects are preferred within all classes of psychotropic drugs.
