Eperisone is a muscle relaxant. It works on the centres in the brain and spinal cord to relieve muscle stiffness or spasm without reduction in strength. This improves pain and movement of muscles. Eperisone is a centrally acting skeletal muscle relaxant that decreases muscle spindle sensitivity through the inhibition of spontaneous discharge of γ-motor neurons. It also exhibits vasodilatory action through antagonism of Ca influx.
