Completed · Phase 3
Conditions studied: Multiple Sclerosis, Muscle Spasticity, Spinal Cord Injury, Stroke
In brief
This study is being conducted to compare the impact of somnolence (sleepiness) on cognition (awareness) as well as the safety and effectiveness of tizanidine hydrochloride capsules versus Zanaflex® (tizanidine hydrochloride tablets) taken while in the fed state (just after a meal) and in the fasted state (before a meal) in patients with moderate to severe spasticity.
