Mechanism of action

This combination antacid works through a dual mechanism: aluminum hydroxide and magnesium hydroxide both act as bases that directly neutralize excess stomach acid, raising gastric pH and providing symptomatic relief of acid-related conditions. The formulation combines these two hydroxides to balance efficacy while minimizing individual side effects (aluminum tends to cause constipation while magnesium tends to cause diarrhea).
