title: Low dose bromocriptine: a study of acute effects in chronic mediated schizophrenics.
abstract: An acute low oral dose (2 mg) of bromocriptine was administered in a randomized double blind fashion to 11 chronic symptomatic mediated schizophrenic patients. There was an overall improvement for the group on the Brief Psychiatric Rating Scale (BPRS) following bromocriptine. Plasma homovanillic acid, 3-methoxy-4-hydroxyphenylglycol, and vanilloyl-mandelic acid concentrations were unchanged after bromocriptine. Bromocriptine concentrations in the plasma showed a large inter-individual variation. There was a significant inverse correlation between plasma bromocriptine concentration and total BPRS score at 60 minutes post-bromocriptine administration. These results suggest a need for further replication in a larger study population and a need for controlled studies with chronic administration of low dose bromocriptine in chronic medicated schizophrenic patients.
