A double-blind clinical investigation of cis(Z)-clopenthixol and clopenthixol in chronic schizophrenic patients.

The therapeutic effect of the neuroleptic cis(Z)-clopenthixol has been compared with that of clopenthixol in mainly chronic schizophrenic patients in a double-blind 8-week trial. Forty-nine of the 54 patients in the trial received clopenthixol in the pre-trial period. Ratings with CGI and a single side effects form were done at weeks 0, 2, 4, 6, and 8. The registration of therapeutic effect at week 8 indicated a symptomatological status quo in both groups of patients while there was a tendency of slightly less interference by cis(Z)-clopenthixol with patient's functioning than by clopenthixol. The ratio of therapeutically equipotent cis(Z)-clopenthixol/clopenthixol doses was found to be 1:2. It is suggested that long-term treatment with clopenthixol advantageously may be replaced by cis(Z)-clopenthixol.

Neuroleptic treatment of oligophrenic patients. A double-blind clinical multicentre trial of cis(Z)-clopenthixol and haloperidol.

One hundred mentally retarded patients from five Finnish institutions took part in a double-blind, double-dummy 12-week trial assessing the therapeutic effect of cis(Z)-clopenthixol and haloperidol. Assessments including CGI by psychiatrists and ward personnel as well as a 4-item target symptom scale was done at weeks 0, 4, 8, and 12. Improvement was registered by the psychiatrists in 16, 21, and 24 cis(Z)-clopenthixol patients and in 11, 6, and 7 haloperidol patients at weeks 4, 8, and 12, respectively--the difference between the two drugs being significant at weeks 8 and 12. The ratings of CGI by the personnel and the 4-item scale by the psychiatrists showed less improvements and no significant differences between the two drugs. While the overall impression of interference of patients' functioning by side-effects were in the favour of haloperidol the number of single side effects increased more with haloperidol than with cis(Z)-clopenthixol during the 12 weeks. Average doses administered at week 12 were 34 mg cis(Z)-clopenthixol and 5 mg haloperidol.
