Abstract
For the treatment of acute mania, no single drug is sufficiently effective in daily clinical routine for all patients. Drug combinations are often prescribed but poorly investigated. The present study examined whether a treatment with a neuroleptic drug (zuclopenthixol) combined with a benzodiazepine (clonazepam) was superior to a treatment with lithium and the same benzodiazepine (lithium citrate and clonazepam). Twenty‐eight hospitalized patients with a DSM‐III‐R manic episode were included, randomized to fixed drug doses and observed up to 28 days. Degree of mania, side effects and patients satisfaction with the treatment were registered. Approximately two thirds of the patients improved fully or partially on both drug combinations. Furthermore no statistically significant differences were found regarding acceptance and tolerance of the two drug combinations. The present drug combination are only two among several which deserve a thorough examination in order to prevent a random polypharmacy for treatment of mania.
