Long-Term Use of Omeprazole: Effect on Haematological and Biochemical Parameters.

Background: Long-term use of proton pump inhibitors (PPIs) is believed to have various potential adverse events. Omeprazole is a part of PPIs most commonly prescribed worldwide; it irreversibly binds to H+-K+ ATPase enzyme system in the gastric parietal cells to reduce secretion of H+ ions into the lumen of stomach.
