Spasmolytic is a term used to describe drugs that help relieve muscle spasms or contractures. Some synonyms for spasmolytic include antispasmodic, myorelaxant, muscle relaxant, and anticonvulsant. Antispasmodic medications work by reducing muscle contractions and relaxing the affected muscle groups, while muscle relaxants help to decrease muscle tension and provide relief from pain and discomfort. Myorelaxants are drugs that suppress muscle contractions, either through their direct action on muscle fibres or by inhibiting the signals that cause muscle contractions. Anticonvulsants are medications that help to prevent seizures but have also been found to reduce muscle spasms and tremors.
