How does this medicine work? What are its effects ?
Tizanidine belongs to the class of medications called muscle relaxants. It is used to treat spasticity, a condition where the muscles are prone to spasms or cramps, or become rigid due to a health condition, such as a spinal cord injury or multiple sclerosis. Muscle relaxants work by blocking the excessive discharges of nerve cells that regulate muscle movement.
The benefits of tizanidine result from its effects on the nervous system and are felt within one hour of taking the first dose.
