Mechanism of action

Alginate works by reacting with gastric acid to form a viscous gel that floats on top of the gastric contents. This gel acts as a barrier to prevent the reflux of acid into the esophagus, thus reducing symptoms of heartburn and acid reflux. The gel also helps to protect the gastric mucosa from irritation.

Pharmacodynamics

The pharmacodynamic properties of alginate are characterized by its ability to form a protective gel in the acidic environment of the stomach. This gel not only acts as a physical barrier to reflux but may also help to enhance mucosal defense mechanisms. The degree of gel formation and its effectiveness in reducing symptoms can vary based on the concentration of alginate and the presence of other compounds.

Pharmacokinetics

Alginate is not absorbed systemically; instead, it acts locally in the gastrointestinal tract. Its gel-forming ability is dependent on the pH of the environment, with optimal performance at lower pH levels. The gel remains in the stomach for a variable duration, providing prolonged symptomatic relief. Alginate is excreted as an unabsorbed substance.

Pregnancy

Breast-feeding
