title: Zuclopenthixol and perphenazine in patients with acute psychotic states. A double-blind multicentre study.
abstract: Fifty-four patients with acute psychotic states were included in a double-blind multicentre study of zuclopenthixol and perphenazine given orally. Fourteen patients had not received test preparations for a minimum of 3 weeks as stated in the protocol, and were excluded. The remaining 40 patients received the test preparations for 3 to 12 weeks, with an average of 49 days for patients receiving zuclopenthixol and 45 days for patients receiving perphenazine. Clinical evaluations were done at baseline and at weeks 1, 2, 4, 6, 8, and 12 including the CGI, a CPRS subscale for schizophrenia, and the UKU Side Effects Rating Scale. The patients received on average 37 mg zuclopenthixol or 30 mg perphenazine daily. Statistically, significant reductions on the CGI, severity of illness, and on the CPRS (total score) were found for both drugs when comparing baseline with later scores. No significant differences between the drugs were found. It was also impossible to demonstrate a difference in clinical profile between the two drugs on the basis of the single items on the CPRS. Although small differences between the two drugs were found, as regards number and type of side effects, it is concluded that the pattern of side effects was almost identical in the two treatment groups.
