This chemical is primarily used in the pharmaceutical industry as an active ingredient in antacid formulations. It works by neutralizing excess stomach acid, providing relief from conditions such as heartburn, acid indigestion, and gastroesophageal reflux disease (GERD). Its aluminum-based composition helps in protecting the stomach lining by forming a protective layer, which also aids in the healing of ulcers. Additionally, it is sometimes incorporated into topical medications for its astringent properties, helping to reduce skin irritation and inflammation. Its dual action of acid neutralization and protective barrier formation makes it a valuable component in gastrointestinal and dermatological treatments.
