Hydroxyzine hydrochloride (Atarax, UCB 4492) is a tranquillizer which has attracted much interest in the United States, where it has undergone a series of clinical trials with encouraging results. In order to test the claims of American investigators a trial of hydroxyzine was made on a group of psychotic and psychoneurotic patients in a large mental hospital. The effectiveness of hydroxyzine in controlling the tobacco habit was also tested by using volunteer nurses at the hospital. Their observations provided useful information on the subjective action and side effects of the drug. A small number of young children attending a local child guidance clinic were also included in the clinical trial.
