mus·cle re·lax·ant

a drug with the capacity to reduce muscle tone; may be either a peripherally acting muscle relaxant such as curare and act to produce blockade at the neuromuscular junction (and thus useful in surgery), or act as a centrally acting muscle relaxant exerting its effects within the brain and spinal cord to diminish muscle tone (and thus useful in muscle spasm or spasticity).

muscle relaxant

Anesthesiology An agent used in anesthesiology to facilitate airway management, control alveolar ventilation, abolish motor reflexes, and provide the muscle relaxation. Depolarizing agents, eg succinylcholine, cause a prolonged depolarization of the motor end plate. Nondepolarizing agents, eg pancuronium, are competitive inhibitors of acetylcholine at the motor end plate See Depolarizing agent, Nondepolarizing agent.
