Proton pump inhibitor brand and generic names
This PPI list covers six ingredient examples. It is a name reference, not a complete list of every strength, formulation, or store brand. A brand family may include more than one product, so keep any extra words on the label attached to the name.
Common PPI name pairs
| Brand name | Generic name | Class or type |
|---|---|---|
| Prilosec | omeprazole | Proton pump inhibitors |
| Nexium | esomeprazole | Proton pump inhibitors |
| Protonix | pantoprazole | Proton pump inhibitors |
| Prevacid 24 HR | lansoprazole | Proton pump inhibitors |
| Aciphex | rabeprazole sodium | Proton pump inhibitors |
| Dexilant | dexlansoprazole | Proton pump inhibitors |
Understanding proton pump inhibitors
The “proton pump” in the class name is an enzyme involved in the final step of stomach acid production. For learning purposes, connect PPI with the family first, then recall the individual ingredient. Knowing that Nexium is a PPI is a different task from remembering that its generic is esomeprazole.
Delayed release is a formulation term you will see on many PPI labels. It describes when the medicine is released; it is not another drug class. Dexilant contains dexlansoprazole in a dual delayed-release formulation, while Aciphex tablets contain delayed-release rabeprazole sodium. Keep the ingredient and the release description as separate pieces of information.
Pepcid—famotidine is an H2 blocker, not a PPI. Both appear in acid-reducing medicine lists, but grouping them by purpose alone hides an important class distinction.
Naming patterns and memory tips
The full -prazole ending links omeprazole, esomeprazole, pantoprazole, lansoprazole, dexlansoprazole, and rabeprazole. Read the beginning as carefully as the ending: the shared stem tells you the family, while the opening letters help you distinguish the ingredients.
Pair the closest-looking names before mixing the whole list. Practice Prilosec—omeprazole beside Nexium—esomeprazole, and Prevacid—lansoprazole beside Dexilant—dexlansoprazole. The added letters belong to different generic names; they are not optional spelling variations.
- Prilosec and Protonix start similarly, but pair with omeprazole and pantoprazole respectively.
- Aripiprazole ends with the same letters as these PPIs but is an atypical antipsychotic. A suffix is a clue, not proof of class membership.
Commonly confused PPI names
Prilosec and Zegerid
Prilosec pairs with omeprazole. Zegerid products combine omeprazole with sodium bicarbonate. Omeprazole alone is therefore an incomplete answer for the combination.
Lansoprazole and dexlansoprazole
These are related but distinct ingredient names. Keep the full generic beside its brand instead of shortening both to the same -lansoprazole ending.
A familiar brand and a specific product
Prevacid 24 HR is a lansoprazole product. The extra words identify the product; recognizing the ingredient does not establish that every Prevacid product has identical labeling or use instructions.
