Summary

Verapamil has been found in some but not all studies to have antimanic activity. Therefore, we investigated the use of verapamil, alone or as an adjunctive treatment, in manic patients who did not respond to an initial adequate trial of lithium. Each study phase lasted three weeks. Subjects were treated openly with lithium in Phase 1 (n=45). Those who failed to respond were randomly assigned to double-blind treatment in Phase 2 with either verapamil (n=10) or continued lithium (n=8). Phase 2 responders were continued on the same medication in Phase 3. Phase 2 nonresponders (n=10) were assigned to combined verapamil/lithium in Phase 3.

Conditions

Interventions

DRUG

Lithium

Treatment with lithium carbonate was initiated at a dose of 900-1200 mg/day. Serum lithium levels were monitored twice weekly, and the dose was adjusted to attain target levels between 0.8 and 1.0 mmol/L by the end of week one, with subsequent levels as high as 1.4 mmol/L permitted if needed.

DRUG

verapamil

The initial dose of verapamil was 80 mg b.i.d., and this was raised by 80 mg/day every three days to a maximum of 480 mg/day, unless intolerable side effects were produced at a lower level, in which case the dose was maintained at the highest tolerated amount.

DRUG

verapamil plus lithium
