Pantoprazole and omeprazole are two proton pump inhibitors (PPIs) that are used to treat digestive conditions. Both drugs can be used for gastroesophageal reflux disease (GERD), a more chronic form of heartburn, and erosive esophagitis. They work by decreasing acid secretion in the stomach. While pantoprazole and omeprazole are similar medications, they also have some differences.
What are the main differences between pantoprazole and omeprazole?
Pantoprazole (Pantoprazole coupons) is the generic name for Protonix and is currently purchased with a prescription only. It is FDA-approved to treat GERD in adults and children aged 5 years and older for a usual duration of up to 8 weeks. Pantoprazole (more Pantoprazole details) is supplied as a delayed-release tablet or liquid suspension. It can also be administered as an intravenous (IV) injection at a hospital or clinic.
Omeprazole (Omeprazole coupons) is also known by its brand name, Prilosec, and can be purchased with a prescription or over-the-counter. It works similar to pantoprazole as a PPI. However, it is also FDA-approved to treat duodenal ulcers, helicobacter pylori (H. pylori) infections, and gastric ulcers in addition to GERD and erosive esophagitis. Omeprazole (more Omeprazole details) can treat GERD in adults and children 1 year and older. It comes as a delayed-release capsule, tablet, and liquid suspension.

Conditions treated by pantoprazole and omeprazole
Pantoprazole and omeprazole are both FDA approved to treat heartburn symptoms from GERD and erosive esophagitis. PPIs like pantoprazole and omeprazole are more potent than regular antacids, such as histamine (H2) blockers. They are usually prescribed for short-term treatment not lasting more than 8 weeks long.
Pantoprazole and omeprazole can also treat hypersecretory conditions that cause the stomach to produce too much gastric acid. Zollinger-Ellison syndrome is a condition that can cause acid hypersecretion and involves tumors in the pancreas or duodenum (first part of the small intestine).
Pantoprazole and omeprazole can also help treat other conditions such as duodenal ulcers, gastric or stomach ulcers, and peptic ulcers. These ulcers are often caused by an infection from a bacteria called H. pylori. While omeprazole is approved to treat H. pylori in combination with other drugs, pantoprazole is used off label for this infection as well.
Other off-label uses for both drugs include Barrett’s esophagus and ulcers that stem from the use of nonsteroidal anti-inflammatory drugs (NSAIDs).
|Gastroesophageal Reflux Disease (GERD)||Yes||Yes|
|H. Pylori infection||Off-label||Yes|
|NSAID induced ulcers||Off-label||Off-label|

Is pantoprazole or omeprazole more effective?
Pantoprazole and omeprazole have been shown to be effective at treating GERD. In a meta-analysis that pooled over 40 different studies, results found no significant differences in effectiveness between PPIs. Pantoprazole was found to be equally as effective as omeprazole. Some double-blind clinical trials also included other PPIs such as Nexium (esomeprazole), lansoprazole (Prevacid), and rabeprazole (Aciphex).
One study included in the meta-analysis found that pantoprazole was more effective than omeprazole in the treatment of stomach ulcers. Results pooled from 5 studies in the review-based effectiveness on healing rates. While pantoprazole was found to be more effective, there may have been flaws with unequal dosing.
Pantoprazole and omeprazole are both comparable drugs in terms of effectiveness. One may be preferred over the other depending on the condition being treated and the cost of the medication. Consult a doctor to determine which PPI may be better for you.

Common side effects of pantoprazole and omeprazole
Pantoprazole and omeprazole can cause side effects such as headache, dizziness, nausea, and vomiting. They can also cause other gastrointestinal side effects such as diarrhea, constipation, abdominal or stomach pain, and flatulence or gas. Other shared side effects may include joint pain, upper respiratory tract infections, and asthenia or lack of energy.
Omeprazole can also cause side effects such as acid regurgitation, back pain, and coughing. Pantoprazole has not been studied to show these particular side effects as often.
|Upper respiratory tract infection||Yes||N/A||Yes||2%|
|Weakness/Lack of energy||Yes||N/A||Yes||1%|
Drug interactions of pantoprazole vs. omeprazole
Both pantoprazole and omeprazole can interact with the same drugs. They both can interact with antiretroviral medications such as rilpivirine, atazanavir, and saquinavir. Taking these medications together can alter the effectiveness of the antiretroviral drug and increase its toxicity. Taking pantoprazole or omeprazole with warfarin can increase the risk of bleeding. Therefore, they should not be taken together. While clopidogrel may not affected by pantoprazole, it should be avoided with omeprazole.
Pantoprazole and omeprazole interact with methotrexate, an antimetabolite medication, and can cause an increased risk of toxicity and side effects.
Pantoprazole and omeprazole should not be taken at the same time as iron salts and other drugs that depend on stomach acid for absorption. Other medications that depend on stomach acid for absorption include chemotherapy drugs such as erlotinib and dasatinib and antifungals such as ketoconazole and itraconazole.
Because both PPIs are metabolized in the liver, they may interact with other drugs that are processed by similar enzymes, including the CYP2C19 enzyme. However, according to the FDA label, some of these drugs, including phenytoin, citalopram, and diazepam, were not shown to have a significant interaction with pantoprazole. Still, it is important to discuss any medications you take with a doctor before taking a PPI.
PPIs can affect the results of certain lab tests. PPIs are known to cause false positives for THC urine tests.
|Citalopram||Selective serotonin reuptake inhibitor (SSRI) antidepressant||No||Yes|
|St. John’s Wort||Herbal||Yes||Yes|
*This may not be a complete list of all possible drug interactions. Consult a doctor with all medications you may be taking.
Warnings of pantoprazole and omeprazole
Pantoprazole and omeprazole are not recommended for long-term use. Long-term use has been associated with an increased risk of bone fractures. If you have osteoporosis, you may want to monitor any use of PPIs.
Some data has suggested that PPI drugs can increase the risk of cardiovascular events such as heart attack and stroke. However, the FDA and other reports reinforce the benefits of PPIs outweigh this risk.
Because pantoprazole and omeprazole are processed in the liver, they may be adjusted or avoided in those with liver impairment.
Pantoprazole and omeprazole can worsen or increase the risk of systemic lupus erythematosus, a rare autoimmune disease.
Treatment with PPIs can increase the risk of diarrhea from Clostridium difficile infections. This risk may be higher in those who are hospitalized for a long time.
Both pantoprazole and omeprazole are in Pregnancy Category C and may cause harm to the unborn baby. Consult a doctor or healthcare provider if you are pregnant or breastfeeding.
