Proton Pump Inhibitors (PPIs) for Gastroesophageal Reflux Disease (GERD)
Introduction to PPIs for GERD
Proton pump inhibitors (PPIs) are a cornerstone in the management of gastroesophageal reflux disease (GERD). They work by reducing stomach acid production, thereby alleviating symptoms and promoting healing of the esophagus. This article synthesizes current research on the efficacy, dosing strategies, and long-term use of PPIs for GERD.
Efficacy of PPIs in GERD Treatment
PPIs are highly effective in managing GERD symptoms and promoting esophageal healing. Studies have shown that PPIs significantly reduce heartburn and regurgitation, which are common symptoms of GERD 13. For instance, a meta-analysis demonstrated that PPIs are more effective than placebos in reducing gastric acidity and improving histologic aberrations in both infants and children .
Dosing Strategies for PPIs
Once-Daily vs. Twice-Daily Dosing
While once-daily dosing of PPIs is standard practice, some clinicians opt for twice-daily dosing to manage persistent symptoms. However, evidence suggests that increasing the dose to twice daily does not significantly improve GERD symptoms compared to once-daily dosing . A systematic review and meta-analysis found no meaningful improvement in heartburn and regurgitation with twice-daily dosing .
On-Demand vs. Continuous Maintenance Therapy
On-demand PPI therapy, where patients take medication only when symptoms occur, has been compared to continuous maintenance therapy. Research indicates that on-demand therapy is as effective as continuous therapy for non-erosive and mild erosive reflux disease, while significantly reducing the amount of PPI use . However, continuous therapy is more effective for patients with severe esophagitis .
Long-Term Use of PPIs
Risks and Benefits
Long-term use of PPIs is generally safe but should be periodically reevaluated to ensure the lowest effective dose is used. The American Gastroenterological Association recommends long-term PPI use for patients with GERD and acid-related complications, such as erosive esophagitis or peptic stricture, as well as for those with Barrett's esophagus . However, they advise against routine use of probiotics, increased intake of calcium, vitamin B12, or magnesium, and routine monitoring of bone mineral density or serum creatinine .
Alternatives to Long-Term PPI Use
For patients with moderate-to-severe regurgitation unresponsive to once-daily PPI therapy, laparoscopic magnetic sphincter augmentation (MSA) has been shown to be more effective than increasing PPI dosage . MSA significantly improves regurgitation symptoms and quality of life, with a high percentage of patients discontinuing PPI therapy post-procedure .
Conclusion
PPIs remain a highly effective treatment for GERD, particularly for short-term symptom relief and esophageal healing. While once-daily dosing is generally sufficient, on-demand therapy can be a viable long-term strategy for many patients, reducing overall PPI use. Long-term PPI therapy should be carefully managed to minimize risks, and alternative treatments like MSA may be considered for patients with persistent symptoms.
