์์ฉ ๊ธฐ์ : Magnesium is a critical intracellular cation and a cofactor for over 300 enzymatic reactions. * **Neuromuscular & CNS:** Magnesium competes with calcium at the motor endplate, decreasing acetylcholine release and reducing motor nerve impulse transmission, leading to muscle relaxation and CNS depression. * **Cardiovascular:** Acts as a physiological calcium channel blocker, slowing sinoatrial node impulse formation and prolonging conduction time โ **antiarrhythmic effect**. * **Gastrointestinal:** Poorly absorbed in the GI tract, it creates an osmotic gradient that draws water into the intestinal lumen โ **osmotic cathartic effect**. * **Topical:** Creates a hypertonic environment that draws out fluid and exudate from localized swellings or abscesses.

Signs of **hypermagnesemia** (magnesium toxicity) include loss of deep tendon reflexes, severe muscle weakness, hypotension, respiratory depression, heart block, and potentially cardiac arrest. > **Treatment:** Discontinue administration immediately. Administer **intravenous calcium** (e.g., calcium gluconate 10%) slowly to antagonize the cardiovascular and neuromuscular effects. Provide respiratory support (intubation and ventilation) and fluid therapy as needed.
