Bromocriptine in augmentation of antipsychotic response in chronic schizophrenia: a negative pilot report.
To further assess the usefulness of bromocriptine in treatment of schizophrenia seven inpatient chronic schizophrenics with acute exacerbation who had failed to respond to four weeks of antipsychotic therapy were treated with bromocriptine 2.5 mg daily for a treatment duration varying from one dose to four weeks while their antipsychotic dose was continued unchanged. Mean age of patients was 38.9 +/- 11.6 years and mean number of prior psychiatric hospitalizations was 12.0 +/- 7.2. Patients were rated with the Brief Psychiatric Rating Scale prior to the first bromocriptine dose, at 24 hours after dosage initiation, and at weekly intervals. One patient showed clinically significant improvement in both positive and negative schizophrenic symptoms. One patient showed slight improvement in unusual thought content, and four patients were clinically unchanged. One patient significantly worsened after the first dose. Factors possibly contributing to response and non-response are discussed. This is a report of an open study in 7 patients. It is the only report of bromocriptine treatment in patients previously shown unresponsive to antipsychotics and whose antipsychotics dose was held constant throughout the study. Addition of bromocriptine to the antipsychotic regimen remains an unproven treatment approach which may be considered only in patients refractory to or inadequately controlled with antipsychotics.
