Piperacetazine versus thioridazine in the treatment of organic brain disease: a controlled double-blind study

Abstract

In a double-blind cross-over study, 50 geriatric patients with organic brain disease were divided into two groups. One group first received piperacetazine for 15 days and then thioridazine for 15 days. For the other group the sequence was reversed. Piperacetazine proved to be at least as effective as thioridazine and seemed to be more effective against certain target symptoms; side effects were less common and less severe.
