Clonazepam treatment of five lithium-refractory patients with bipolar disorder

Published Online:https://doi.org/10.1176/ajp.146.1.77

The authors describe the first five patients enrolled in an open clinical trial of clonazepam as a maintenance treatment in lithium- refractory bipolar disorder. All patients relapsed quickly after taking clonazepam (one within 2 weeks and four within 10-15 weeks), and the study was prematurely terminated. The results cast doubt over the usefulness of clonazepam as a prophylaxis in lithium-resistant bipolar patients who have histories of psychotic mania or delusional depression.
