This information is based on the standard use of omeprazole. ## Overview Omeprazole is a proton pump inhibitor (PPI) that suppresses gastric acid secretion by irreversibly inhibiting the H+/K+-ATPase enzyme system (the proton pump) in gastric parietal cells. ## Primary Indications * Gastroesophageal reflux disease (GERD) - erosive esophagitis, symptom relief. * Peptic ulcer disease (PUD) - duodenal ulcers, gastric ulcers. * Healing of NSAID-associated gastric ulcers. * H. pylori eradication (in combination with antibiotics). * Zollinger-Ellison syndrome. ## Adult Dosing * **GERD (maintenance):** 20 mg once daily. * **GERD (healing erosive esophagitis):** 20 mg once daily for 4-8 weeks. Doses up to 40 mg once daily may be used. * **Duodenal Ulcers:** 20 mg once daily for 4 weeks. * **Gastric Ulcers:** 20 mg once daily for 4-8 weeks. * **NSAID-associated ulcers:** 20 mg once daily for 4-8 weeks. * **H. pylori eradication:** Typically 20 mg twice daily in combination with clarithromycin and amoxicillin or metronidazole for 10-14 days. * **Zollinger-Ellison Syndrome:** Initial dose is typically 60 mg once daily. Doses can range from 20 mg to 120 mg daily. Doses over 80 mg should be divided and given twice daily. Maximum dose: Generally 40 mg daily for most indications, except Zollinger-Ellison syndrome where higher doses are used. ## Pediatric Dosing Dosing in pediatric patients is highly variable and depends on age, weight, and indication. Local protocol should be consulted. General guidelines: * **GERD (1-16 years):** 10 mg once daily for up to 8 weeks. Doses up to 20 mg once daily may be used for more severe erosive esophagitis. * **GERD (infants < 1 year):** Dosing varies significantly. Consult specific guidelines. ## Dose Adjustments No dose adjustment is typically required for hepatic or renal impairment, but caution is advised with severe hepatic impairment. ## Contraindications Known hypersensitivity to omeprazole, its substituted benzimidazoles, or any component of the formulation. ## Adverse Effects Common: Headache, diarrhea, abdominal pain, nausea, vomiting, flatulence. Less common: Dizziness, rash, fatigue. Long-term use may be associated with increased risk of: * Fractures (hip, wrist, spine). * Clostridium difficile infection. * Vitamin B12 deficiency. * Hypomagnesemia. * Pneumonia. ## Key Drug Interactions * **Clopidogrel:** Omeprazole may decrease the antiplatelet effect of clopidogrel. Consider alternative PPIs or separation of dosing. * **Ketoconazole, Itraconazole, Posaconazole, Erlotinib, Gefitinib:** Omeprazole can decrease absorption of these drugs due to increased gastric pH. * **Methotrexate:** Omeprazole may increase methotrexate levels. * **Rilpivirine, Atazanavir:** Coadministration is generally not recommended due to decreased plasma concentrations. * **CYP2C19 Substrates:** Omeprazole is a moderate inhibitor of CYP2C19. May affect metabolism of drugs like citalopram, escitalopram, and warfarin. ## Monitoring * For long-term use, monitor for signs of vitamin B12 deficiency, hypomagnesemia, and bone fractures. * Monitor for signs and symptoms of C. difficile infection. * Monitor INR if co-administered with warfarin. ## Clinical Pearls * Administer capsules or tablets on an empty stomach, preferably before breakfast. * Do not chew or crush delayed-release capsules; swallow whole. If unable to swallow whole, open capsule and sprinkle contents on applesauce, yogurt, or juice and consume immediately. * May mask symptoms of serious underlying conditions, such as malignancy. * Long-term use should be reserved for patients who require ongoing acid suppression and for whom alternative therapies are not suitable. *** *Disclaimer: This information is for educational purposes only and does not constitute medical advice.
