Magnesium Sulfate: Versatile Magnesium Source for Pharma and Industry
Magnesium sulfate is an inorganic salt available in anhydrous and hydrated forms (most commonly the heptahydrate, Epsom salt). In pharmaceutical applications, it is used parenterally as an anticonvulsant (eclampsia/pre-eclampsia), as a saline laxative, and as a source of magnesium for electrolyte replacement. Industrially, it serves as a drying agent, fertilizer component, and processing aid.

Formulation Applications
Injectable magnesium sulfate solutions (typically 10–50% w/v) are used as first-line treatment for seizure prophylaxis in eclampsia and for correction of hypomagnesemia. Orally, the heptahydrate acts as a saline laxative at doses of 5–15 g. The anhydrous form is a common laboratory drying agent for organic solvents and extracts. In agriculture, magnesium sulfate is a widely used water-soluble fertilizer for magnesium-deficient soils. In industrial applications, it is used in textile dyeing, paper production, and as a component of bath salts and topical soak preparations. The heptahydrate effloresces in dry air and should be stored in sealed containers.
