However, some formulations of omeprazole, commonly known as proton pump inhibitors (PPIs), may include aluminum or magnesium in the form of antacids to help neutralize stomach acid [1]. These additional ingredients are not part of the active pharmaceutical ingredient omeprazole but are combined to provide faster symptom relief [1].
What ingredients are in omeprazole products?

Always check the product's active and inactive ingredients list for specific details [2].
How do omeprazole and antacids work together?
Omeprazole is a proton pump inhibitor that works by reducing the amount of acid produced by the stomach [3]. Antacids, such as those containing magnesium hydroxide and aluminum hydroxide, work by chemically neutralizing existing stomach acid, offering rapid but temporary relief [4]. When combined in a single product, the antacid provides immediate acid reduction, while omeprazole works over a longer period to suppress acid production [1].
