Tripilex is a medication that combines three active ingredients: a proton pump inhibitor (omeprazole), an antacid (magnesium hydroxide), and an alginate (sodium alginate). It is primarily used to treat conditions related to excess stomach acid, such as gastroesophageal reflux disease (GERD) and peptic ulcers. The combination works by reducing stomach acid production, neutralizing existing acid, and creating a protective barrier that helps prevent acid reflux. Always consult a healthcare professional for appropriate use and potential side effects.
