์์ฉ ๊ธฐ์ : Acts locally in the gastrointestinal tract: * **Antacid**: Neutralizes gastric hydrochloric acid (HCl) โ raises gastric pH. Raising pH >4 minimizes pepsin proteolytic activity, reducing gastric mucosal damage. * **Laxative**: Poorly absorbed magnesium ions create an osmotic gradient โ draws water into the intestinal lumen โ distends the bowel โ stimulates peristalsis. * **Rumen Alkalinizer**: Directly neutralizes excess lactic acid produced during grain overload โ increases rumen pH and alters rumen microflora activity.

- Renal disease (due to risk of hypermagnesemia)
- Gastric outlet obstruction (for aluminum-containing products)
- Use cautiously in patients on sodium- or potassium-restricted diets (some products contain significant amounts)
์ด์๋ฐ์
- Diarrhea or frequent loose stools
- Hypermagnesemia (especially in patients with severe renal insufficiency)
- Constipation (if using combination products with aluminum)
- Hypophosphatemia (with chronic use of aluminum-containing products)

- Quinidine ยท Increased absorption or pharmacologic effect may occur
- Sodium Polystyrene Sulfonate ยท May decrease the potassium-lowering effectiveness; may cause metabolic alkalosis in renal failure patients
- Sustained-release medications ยท May alter absorption by changing GI transit times when used at laxative dosages
- Sympathomimetic agents ยท Increased absorption or pharmacologic effect may occur
- Fluoroquinolones ยท Decreased absorption (chelation); separate doses by at least 2 hours
- Tetracyclines ยท Decreased absorption (chelation); separate doses by at least 2 hours
- Azole Antifungals (Ketoconazole, Itraconazole) ยท Decreased absorption due to increased gastric pH; separate doses by at least 2 hours
- Digoxin ยท Decreased absorption; separate doses by at least 2 hours
- Iron Salts ยท Decreased absorption; separate doses by at least 2 hours
- H-2 Antagonists ยท Decreased absorption; separate doses by at least 2 hours
- Thyroid Hormones ยท Decreased absorption; separate doses by at least 2 hours

Chronic or acute overdose can lead to significant GI upset (severe diarrhea) and electrolyte imbalances (hypermagnesemia, especially in renal failure). Treat symptomatically with fluid therapy and correct electrolyte derangements.
