Ketazolam once daily for spasticity: double-blind cross-over study.

This double-blind cross-over study of 14 severely spastic inpatients with chronic multiple sclerosis reveals that once-daily doses of ketazolam, a new drug, are effective in reducing spasticity in a significant proportion of patients without significant side-effects. Added to the similar findings of an earlier double-blind controlled study of divided doses, the results suggest that this special feature of ketazolam provides a unique flexibility that may be exploited in individual cases.
