How Pyrimet MR Tablet works

Pyrimet MR Tablet is a combination of two medicines: Paracetamol and Chlorzoxazone, which relieve pain and relax the muscles. Paracetamol is an analgesic (pain reliever) and antipyretic (fever reducer). It blocks the release of certain chemical messengers in the brain that are responsible for pain and fever. Chlorzoxazone is a muscle relaxant. It works by acting on the centers in the brain and spinal cord to relieve the muscle stiffness or spasm.
