Prilosec or omeprazole and Nexium or esomeprazole magnesium are proton pump inhibitors (PPIs) that are being used to cure gastric and duodenal ulceration, gastroesophageal reflux disease known as GERD, as well as Zollinger-Ellison disease. Prilosec and Nexium are both accessible as generic medicines and over-the-counter medications or OTC.
Prilosec vs Nexium
The main difference between Prilosec and Nexium is that Nexium has just one isomer of the medication omeprazole, whereas Prilosec includes two. Isomer refers to a molecule that has the same components but is organized differently. So, omeprazole and esomeprazole are formed of the exact basic components but assembled uniquely.
