Antacids
At Epitochem International, we offer a targeted range of antacid-grade excipients and active mineral salts used in the formulation of chewables, suspensions, and effervescent tablets. These compounds, such as Magnesium Hydroxide, Aluminum Hydroxide, and Calcium Carbonate, are critical for neutralizing gastric acid and providing fast, effective relief in gastrointestinal therapies. Our products meet pharmacopeial standards (USP/BP/EP) and are trusted by formulators for their consistency, safety, and functional performance.
