Psychotropic prescriptions for the treatment of schizophrenia in an outpatient clinic.

INTRODUCTION

There is an unpredictable pattern in the prescription of antipsychotics and other psychotropic medications for the treatment of schizophrenia, particularly in resource-limited settings in developing countries.

OBJECTIVE

To determine the psychotropic prescriptions given to patients with schizophrenia in an outpatient clinic of a tertiary hospital and to describe the choices and trends of these prescriptions.

METHODS

This was a cross-sectional descriptive study of prescriptions for adults with schizophrenia. After clinical consultation, patients' case notes were randomly selected over a period of 2 years. Using a structured form, data were extracted from the case notes including biodemographic data, psychotropic medications prescribed and changes made to these prescriptions. Data were analyzed by means of descriptive statistics.

RESULTS

A total of 103 patients were selected, with a mean age of 35.96±9.78 years; 48.5% were males and 51.5% were females; 33% were unemployed and 38% had been hospitalized in the past. There were 231 initial prescriptions and 228 current prescriptions, with about 2.2 prescriptions per patient. Haloperidol (mean dose 14.77±6.28mg and 11.44±5.55mg for initial and current) and other old-generation antipsychotics were the most commonly prescribed for new cases (98%). Mean duration of psychotropic use was 7.78±5.6 years. All the patients were prescribed trihexyphenidyl, and 56.3% of the patients had their medications changed as a result of side effects.

CONCLUSION

There was a very high preference for the use of first-generation antipsychotics for all treatment settings (in- and outpatients), a pattern that is likely to persist.
