Eperisone is primarily used as a muscle relaxant to alleviate muscle stiffness and pain associated with various conditions such as sprains, strains, or musculoskeletal disorders. It works by blocking nerve impulses that cause muscles to contract, promoting relaxation and improving blood flow to the affected areas. This makes it effective in treating symptoms of cervical spondylosis, lower back pain, and other conditions involving muscle spasms. Additionally, it is often prescribed alongside physical therapy or other treatments to enhance recovery and mobility. Its ability to reduce muscle tension also makes it useful in managing conditions like cerebral palsy and post-stroke spasticity, improving overall patient comfort and function.
