The use of drug monotherapy in psychiatric inpatient treatment.
OBJECTIVE
Monotherapy has always been the goal in psychiatric drug treatment, but it does not seem to be very common in everyday practice.


METHODS
The available literature on the frequency of monotherapy or polytherapy with psychotropic agents in psychiatric inpatient treatment is reviewed.


RESULTS
Taken all together (28 studies on 42 treatment facilities), the mean number of psychotropics prescribed was 2.47, the rate of monotherapy was 36.2% and 37.9% of inpatients received > or = 3 different drugs. Comparing the last three decades, a significant decline of the rate of monotherapy was found, topping at 47.8% in the 70s and falling to 19.6% in the 90s. The mean number of psychotropic drugs prescribed rose from 2.2 to 2.9 and the number of patients receiving > or = 3 psychotropics rose from 27.5 to 49.7%.


CONCLUSIONS
Though it is still mandatory to avoid unsound polypharmacy, we must assume that the occasions for polypharmacy are increasing. New psychotropic drugs, increasing comorbidity and augmentation strategies may be incentives for polydrug use. Since in most countries the number of psychiatric beds declines, inpatient treatment has to deal with the most severe, often treatment-resistant patients requiring special therapies.
