Omeprazole Impurities

Omeprazole is a proton pump inhibitor (PPI) used to treat conditions caused by excessive stomach acid, such as gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. It works by inhibiting the proton pump (H+/K+ ATPase) in the stomach lining, which reduces acid production. This helps relieve symptoms like heartburn, acid reflux, and promotes healing of ulcers and damaged tissues in the esophagus. Omeprazole is commonly available in oral form, both over-the-counter and by prescription. While generally well-tolerated, side effects can include headaches, nausea, diarrhea, and abdominal pain. Prolonged use may increase the risk of kidney disease, bone fractures, and vitamin B12 deficiency.
