Dantrolene

Dantrolene is a medication used to treat a rare but serious condition called malignant hyperthermia, which can occur during anesthesia, causing a dangerous increase in body temperature and muscle rigidity. It works by directly affecting muscle cells to reduce abnormal muscle activity and heat production. Dantrolene is also sometimes used to manage certain muscle spasticity conditions, helping relax overly tense muscles. It is administered under medical supervision due to potential side effects, including liver problems and muscle weakness. Overall, dantrolene helps prevent or control severe muscle-related reactions in specific medical situations.
