Storage & Patient Advice

Missed Dose

Not applicable (used as needed); take when symptoms occur-do not double doses.

Stopping the Medicine

Safe to stop anytime

Overdose

Usually minor GI effects (bloating/abdominal distension, belching; possible constipation); very large/prolonged excessive intake may cause hypercalcemia/alkalosis (milk-alkali syndrome); treat symptomatically and seek medical advice if large amounts ingested.

Pharmacology

Mechanism of Action

Sodium alginate reacts in gastric acid to form a viscous, buoyant gel ‘raft’ that sits on top of stomach contents and reduces reflux; calcium carbonate and sodium bicarbonate neutralize gastric acid to relieve heartburn.

Onset of Action

Rapid-typically within minutes (about 3-5 minutes).

Duration of Effect

Up to about 4 hours (often ~2-4 hours).

Half-Life

Not applicable (no meaningful systemic half-life; local GI action with minimal systemic absorption).

Bioavailability

Primarily local action in the stomach with negligible systemic absorption; efficacy is physical/chemical and not dependent on systemic bioavailability.

Metabolism

Not systemically metabolized (alginate not absorbed; bicarbonate/carbonate neutralization is a local chemical reaction rather than hepatic metabolism).

Protein Binding

Not applicable (no clinically relevant systemic absorption, therefore no meaningful plasma protein binding).
