Promazine was administered to six hyperactive retarded boys in a long-term double-blind study. There were four dose levels —40, 60, 80, and 160 mg per day. The effect on activity level was measured with actometers. There was no effect on daytime activity when the placebo and drug levels were compared. There was a significant but clinically unimportant effect on night time activity.
