Management of Gastroesophageal Reflux Disease
Introduction to Prokinetics
- The American Gastroenterological Association recommends against the use of metoclopramida as monotherapy or adjuvant empirical therapy in patients with gastroesophageal reflux disease (Grade D) 1
- The American Gastroenterological Association establishes that prokinetics should be personalized to the specific phenotype of gastroesophageal reflux disease, not used empirically 2
Clinical Guidelines on Prokinetics
- The American Gastroenterological Association recommends that prokinetics be considered only in specific situations, such as regurgitation or eructation predominant symptoms, where baclofen (a GABA-B agonist) may be considered 2
- Prokinetics are indicated only when delayed gastric emptying is documented through a gastric emptying study, in cases of coexisting gastroparesis 2
Algorithm for Managing Refractory Gastroesophageal Reflux Disease
- The American Gastroenterological Association recommends optimizing proton pump inhibitor therapy by increasing the dose to twice a day if the patient is taking it once a day, and verifying the timing of administration (30-60 minutes before meals) 1, 3, 4
- Patients who do not respond to proton pump inhibitors twice a day should be considered therapeutic failures 1, 3
- Endoscopy is indicated when there is no adequate response to proton pump inhibitors twice a day, to look for erosive esophagitis, hiatal hernia, and Barrett's esophagus 2, 3, 5
Diagnostic Testing
- Prolonged pH monitoring should be performed after suspending proton pump inhibitors for 7 days, and preferably using wireless monitoring for 96 hours if available 1, 2, 4
- If the acid exposure time is less than 4.0% on all days, it is likely functional heartburn, not gastroesophageal reflux disease 4
- If the acid exposure time is greater than 4.0% on one or more days, it confirms true gastroesophageal reflux disease 4
Adjuvant Therapy
- Alginate-antacids can be used for intermittent symptoms 2
- Nocturnal H2 antagonists can be used for specific nocturnal symptoms 2
- Baclofen can be used for regurgitation or eructation predominant symptoms 2
- Prokinetics can be used only if coexisting gastroparesis is documented through a gastric emptying study 2
