Dexilant
Protonix
Dexlansoprazole (Dexilant) is a medicine that lowers stomach acid. It belongs to a class of drugs called proton pump inhibitors (PPIs).
Pantoprazole is a drug that reduces stomach acid. It belongs to a class of drugs called proton pump inhibitors (PPIs).
This medicine can help heal damage to your esophagus (the tube connecting your mouth to your stomach). It can also help with heartburn caused by acid reflux. Dexlansoprazole can also treat heartburn from GERD, a condition where stomach acid flows back into your esophagus.
This medicine treats gastroesophageal reflux disease (GERD) and erosive esophagitis (EE) in adults, for up to 10 days. GERD is when stomach acid flows back into your esophagus, causing heartburn. It also treats conditions where your stomach makes too much acid, like Zollinger-Ellison (ZE) Syndrome.
Dexlansoprazole works by reducing the amount of acid your stomach makes. It does this by blocking a specific system in your stomach cells. This helps to heal damage caused by stomach acid.
Pantoprazole works by blocking the enzyme in the stomach that produces acid. This reduces the amount of acid your stomach makes. It helps to heal damage to the esophagus caused by acid reflux.

Dexlansoprazole may hide signs of stomach cancer, so tell your doctor if your symptoms don't improve. It can also cause kidney problems, severe diarrhea from a Clostridium difficile infection, and bone fractures with long-term use. Some people may have severe skin reactions or lupus. Long-term use may also lead to low vitamin B12 or magnesium levels.
Pantoprazole can hide the symptoms of stomach cancer, so tell your doctor if your symptoms don't improve. It may also increase your risk of diarrhea caused by a bacteria called *C. difficile*. Long-term use may increase your risk of bone fractures. This medicine may also cause kidney problems, lupus, low magnesium levels, and polyps in the stomach.

How to Read This dexlansoprazole vs pantoprazole Comparison
dexlansoprazole is classified in the Proton Pump Inhibitor (PPI) drug class, while pantoprazole sits within the Proton Pump Inhibitor (PPI) class. Because both drugs share the same classification, they are often considered interchangeable in theory — but clinical outcomes rarely track that cleanly. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, dexlansoprazole has 39,793 submissions while pantoprazole has 87,680. Those figures reflect cumulative reporting volume — not per-patient risk — so older, widely dispensed drugs typically look worse on count alone. No direct interaction between these two drugs is listed in our FDA-derived dataset, though co-prescription still warrants pharmacist review. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot substitute for clinical judgment. Effectiveness, tolerability, drug-drug interactions with your other medications, kidney and liver function, pregnancy status, insurance formulary, and price all feed into a decision that only a licensed prescriber can make responsibly. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This page is for educational purposes only, is not medical advice, and should not be used to self-switch between dexlansoprazole and pantoprazole — always consult your physician or pharmacist first.
