Omeprazole Side Effects, Dosage & Interactions

Drug Class and Mechanism:

Omeprazole belongs to the group of drugs known as the proton pump inhibitors (PPI) which obstructs the acid that is created in a person’s stomach. Some other drugs that belong to the same class are-

  • Esomeprazole (Nexium)
  • Omeprazole (Prevacid)
  • Pantoprazole (Protonix)
  • Rabeprazole (Aciphex)

 

Proton pump inhibitors (PPI) are utilized for the cure of conditions for example ulcer, the Zollinger-Ellison syndrome and gastro esophageal reflux disease (GERD), all of which are rooted by acid in the stomach. Omeprazole, similar to other PPI’s, obstructs the enzymes (that produce acid) in the stomach wall. As a result of blocking the enzymes, the making of the acid is dwindled, and this permits the esophagus and the stomach to heal.  It was in September 1989 that Omeprazole was approved by the FDA.

This possibly will add to the digoxin toxicity and lessen the efficiencyof ketoconazole.
