1、 Medical use

Spasmodics and anticonvulsants

Pre eclampsia/eclampsia treatment: Through intravenous injection, magnesium sulfate can inhibit central nervous system excitability, prevent or control preeclampsia (seizures caused by gestational hypertension) in pregnant women.

Inhibition of uterine contractions: used to temporarily relieve uterine contractions and prolong pregnancy time during premature delivery.

catharsis

Oral administration: High concentration magnesium sulfate solution retains moisture in the intestine through permeation, softens feces, stimulates intestinal peristalsis, and is used for constipation or preoperative intestinal preparation.

Choleretic acid

Oral administration of low concentration solutions can stimulate the duodenal mucosa, promote bile excretion, and assist in the treatment of cholecystitis or cholelithiasis.

Antiarrhythmic treatment

Intravenous injection is used to treat certain types of arrhythmias (such as apical torsion ventricular tachycardia), especially those associated with hypomagnesemia.

External medication

Wet compress to reduce swelling: Wet compress with 50% solution can alleviate local inflammation or edema (such as venous infusion leakage, cellulitis).

Correcting hypomagnesemia

Supplementing magnesium ions to maintain normal nerve, muscle, and heart function.

2、 Industrial and agricultural use

fertilizer

Provide the magnesium and sulfur elements required by plants to improve soil magnesium deficiency.

Chemical raw materials

Used for manufacturing refractory materials, paper, textiles, ceramics, etc.

desiccant

Anhydrous magnesium sulfate has strong water absorption and is used as a desiccant in organic synthesis.

3、 Precautions

side effect

Rapid intravenous injection may cause facial flushing, hypotension, and respiratory depression; Excessive intake leads to hypermagnesemia (muscle weakness, arrhythmia, coma).

contraindication

Use with caution in patients with renal insufficiency, heart block, and muscle weakness; Pregnant women should strictly follow medical advice.

Drug interactions

Interactions with calcium supplements, neuromuscular blockers, etc. should be avoided in combination or used under monitoring.

4、 Summary

The use of magnesium sulfate varies depending on concentration and administration method:

Intravenous injection: anticonvulsant, antihypertensive, antiarrhythmic.

Oral administration: laxative and choleretic.

External use: reduce inflammation and swelling.

Industry/Agriculture: Used as raw material or fertilizer.

Strictly follow medical advice or instructions when using to avoid risks caused by improper use.
