A minor tranquilizer, ketazolam, was tested in a double-blind, randomized, crossover study of 50 patients for its effects in neurologic spasticity. The drug was compared with diazepam (widely accepted as an effective antispasticity agent) and a placebo. The patients with spasticity were almost all cases of multiple sclerosis (24) or stroke (24). Thirty-nine patients completed the study. There was not statistically significant superiority of either diazepam or ketazolam, but both relieved symptoms significantly better than the placebo, as measured clinically and by electromyographic recording of deep tendon reflexes. Ketazolam is a relatively safe and clinically effective antispasticity agent (especially for patients with multiple sclerosis). The well-known "big 3"--dantrolene sodium, baclofen, and diazepam--produce large and small problems in many individual cases; hence, ketazolam now offers a safe and clinically useful alternative.
