Omeprazole vs Esomeprazole: Difference and Comparison

The gastroesophageal reflux disease (GRED) is treated by using omeprazole and esomeprazole. These two drugs are also used for some other diseases related to stomach acids.

Proton pump inhibitors are the family of both omeprazole and esomeprazole. These drugs can hinder the gastric glands and make the acids at cellular levels.

Key Takeaways

  1. Omeprazole and Esomeprazole are proton pump inhibitors used to treat acid-related stomach disorders.
  2. Esomeprazole is a newer, more potent version of Omeprazole.
  3. Esomeprazole is more expensive than Omeprazole.

Omeprazole vs Esomeprazole

Omeprazole or Prilosec is a medication used to relieve painful stomach conditions like gastroesophageal reflux disease and peptic ulcer disease. The standard dosage is 20mg capsule per day, which reduces the amount of acid in the stomach. Esomeprazole or Nexium is an effective medication to treat stomach acids and ulcers. It regulates stomach acid levels but may cause side effects like bleeding or bruising.

Since it comes under a proton pump inhibitor, it works on selective cells and is irreversible. It is used for both children and adults.

Omeprazole is the combination of sulfinyl sulfer. The omeprazole is observed in the small intestine. It gets stimulated by the food after digestion.

Omeprazole can be detected by examining the plasma or serum in hospitals. The omeprazole is the first proton pump inhibitor made in 1979.

The recommended time for esomeprazole is four to eight weeks. The Nexium will also result in weight gain. The esomeprazole gets metabolized in the liver.
