Phenyramidol, also known as Fenyramidol, is a pharmaceutical drug that acts as a muscle relaxant. It is used to relieve mild to moderate musculoskeletal pain, including neck and shoulder pain, lower back pain, and discomfort associated with muscle spasms caused by injuries or sprains. Phenyramidol works on the centers in the brain and spinal cord, providing relief from muscle stiffness or spasm without reducing muscle strength.
