Mechanism of Action

Relaxo Capsule 50 mg works mainly by blocking the release of calcium ions (Ca2+) from the sarcoplasmic reticulum in skeletal muscles, which prevents calcium ions from binding to the troponin-C region of the muscle, and therefore the muscle remains in a relaxed state. This action interferes with excitation-contraction coupling and leads to the reduction in spasticity.
