Direct muscle relaxants are medications that work by acting directly on the muscle fibers, rather than affecting the nervous system. They help reduce muscle tension and spasms, making them useful in treating conditions like muscle injuries or spasticity associated with neurological disorders. These medications can be administered orally or through injections, depending on the specific drug and the severity of the condition. Common examples include dantrolene and botulinum toxin. While effective, direct muscle relaxants may have side effects, such as weakness or fatigue, and should be used under medical supervision.
