    Study Notes

    • Antacids provide symptomatic relief by increasing gastric pH, but documentation in placebo-controlled trials is lacking.
    • Potential drug-drug interactions with antacids include tetracycline, iron, sulfonylureas, antibiotics, and H2RAs.
    • Antacids are typically used on an as-needed basis, but OTC H2RAs and PPIs may also be used according to package directions.
    • Patients with moderate but non-alarm symptoms may be prescribed medications for GERD if they fail patient-directed treatment.
    • Proton Pump Inhibitors (PPIs) provide the greatest symptom relief and the highest healing rates, especially for patients with erosive disease, moderate-to-severe symptoms, or complications.
    • PPIs work by inhibiting H+/K+-adenosine triphosphate in gastric parietal cells and maintaining extended time with gastric pH >4, which is correlated with the healing of erosive esophagitis.
    • PPIs, such as dexlansoprazole, esomeprazole, lansoprazole, omeprazole, omeprazole and sodium bicarbonate, pantoprazole, and rabeprazole, are available in various forms.
    • PPIs should be discontinued in patients with uncomplicated GERD or the dosage should be lowered after an empirical trial due to rebound acid hypersecretion when used for >8 weeks, making withdrawal difficult.
    • Data is lacking on a proper tapering protocol and various approaches may be considered on a case-by-case basis.
    • BID dosing in those not responding to a standard once daily course of therapy and swapping to an alternative PPI can provide similar efficacy.
    • Common side effects include headache, diarrhea, nausea, and abdominal pain, and increasing concerns with PPI safety have been reported.
    • PPIs interact with various medications and decreasing absorption of ketoconazole or itraconazole, and omeprazole strongly inhibits CYP2C19, which is the enzyme responsible for the conversion of clopidogrel from prodrug to active ingredient.
    • Alternative options exist for pediatric patients and those unable to swallow tablets/capsules, including delayed-release capsules, granules, oral suspension packets, orally disintegrating tablets, capsule sprinkles, or IV formulations.
    • Histamine2 Receptor Antagonists (H2RAs), such as cimetidine, famotidine, and nizatidine, have variable effectiveness in treating patients with mild to moderate GERD and often less than desired response.
    • Disease severity, dosage regimen used, and duration of therapy all affect response, and agent selection should be patient-specific.
    • Common adverse effects include headache, fatigue, dizziness, constipation/diarrhea, and cimetidine has many drug interactions and may inhibit the metabolism of warfarin, theophylline, phenytoin, nifedipine, propranolol, and others.
    • Metoclopramide, a promotility agent, increases LES pressure in a dose-related manner by accelerating gastric emptying.
