Actions and Spectrum
When alginic acid meets gastric acid, it forms a viscous gel that can help reduce acid reflux and protect the esophagus lining.
alginic acid can form gels in the presence of divalent cations like calcium ions.

Contraindication/Caution:
Contraindication:
Caution:
Pregnancy consideration:
Pregnancy category: N/A
Lactation: Excretion into human milk is unknown
Pregnancy Categories:
Category A: well-controlled and Satisfactory studies show no risk to the fetus in the first or later trimester.
Category B: there was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women.
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.
Category N: There is no data available for the drug under this category.
Pharmacology
When alginic acid meets with gastric acid, it forms a viscous gel.
The gel can float on top of the stomach contents, acting as a physical barrier to prevent stomach acid from flowing back into the esophagus.
Pharmacodynamics
Sodium alginate is commonly used in antacid formulations. The gel created by sodium alginate is not absorbed into the bloodstream and remains in the stomach. It continues to provide a protective barrier if it remains in the stomach.
Pharmacokinetics
Absorption
alginic acid remains in the gastrointestinal tract, where it interacts with gastric acid and forms a gel-like barrier.
Distribution
alginic acid does not distribute throughout the body, because it is not absorbed into the bloodstream.
Metabolism
alginic acid is not metabolized in the body.
Elimination and excretion
alginic acid is excreted in the feces.
Administration
alginic acid available in chewable tablet form.
