Multicenter study comparing thioridazine with diazepam and placebo in elderly, nonpsychotic patients with emotional...

Thioridazine was compared with placebo or diazepam or both in 610 elderly, nonpsychotic inpatients in geriatric wards of state hospitals or nursing homes. All patients manifested disruptive and difficult-to-manage behavior that interfered with adjustment to their environment and with proper care and treatment of their medical and emotional problems. Target symptoms such as agitation, anxiety, tension, apprehension, depressed mood, and sleep disturbances showed consistently marked improvement throughout the four-week study, as measured by the modified Hamilton Anxiety Scale, the modified Nurses' Observation Scale for Inpatient Evaluation (NOSIE), and global ratings. Significantly greater improvement on all measures was achieved with thioridazine than with placebo. In addition, greater improvement in the majority of symptoms assessed by the Hamilton Anxiety Scale and NOSIE were seen in patients who received thioridazine than in those given diazepam.
