Anti-acids are an important component of digestive system medications and are widely used to relieve symptoms such as acid reflux, duodenal ulcers, and heartburn. These compounds relieve pain and promote comfort by neutralizing excess stomach acid, counteracting the acidic pH in the stomach, and forming salt and water. Anti-acid APIs mainly include aluminum hydroxide, magnesium hydroxide, calcium carbonate, and sodium bicarbonate. Protheragen-ING offers a full range of anti-acid APIs to support customer research worldwide.
