Chlormezanone in the treatment of insomnia due to rheumatic stiffness.

An open assessment of chlormezanone in the treatment of rheumatic sleep disturbances was carried out in general practice. Sixty-one patients received 400 mg chlormezanone (2 tablets) each night for 2 weeks. Patients' nightly sleep assessment showed a steady improvement over the 2-week period, and overall effectiveness was rated as good or excellent by 75% of patients. Only 1 patient stopped treatment because of side-effects. It was concluded that chlormezanone could prove a useful alternative to current therapy for treatment sleeplessness in rheumatic patients.
