Muscle Relaxant is a category of drugs used to reduce muscle tension and decrease muscle spasms. They are generally divided into two main types: central muscle relaxants and peripheral muscle relaxants. Central muscle relaxants work by acting on the central nervous system to relieve muscle stiffness, commonly used for treating muscle spasms and chronic pain. Peripheral muscle relaxants act directly on muscle cells, primarily used in anesthesia during surgery and in intensive care. The choice and use of muscle relaxants depend on specific medical needs and patient conditions.
