Used primarily to treat malignant hyperthermia, a rare but life-threatening condition triggered by certain anesthetics that causes high body temperature, muscle rigidity, and organ dysfunction. It works by reducing the release of calcium from skeletal muscle cells, helping to relax muscles and prevent severe contractions. Also used in the management of neuroleptic malignant syndrome and certain types of muscle spasticity due to conditions like spinal cord injury, stroke, or multiple sclerosis. Its ability to stabilize muscle function makes it critical in emergency settings during surgery where malignant hyperthermia risk is present.
