Q1. Answer: A
While heartburn responds well to acid suppression with a proton pump inhibitor, regurgitation does not necessarily improve. It is well known that reflux persists despite acid suppression; in some patients, this manifests as troublesome postprandial regurgitation. Transient LES relaxations (TLESRs) are the prime mechanism for persisting reflex, in patients both with and without hiatal hernias.
Baclofen, a gamma amino butyric acid B (GABA-B) agonist, inhibits TLESRs and has potential to improve persisting regurgitation. Metoclopramide has been demonstrated to have no adjunctive value in treating reflux disease. Hyoscyamine and sucralfate are similarly not of particular benefit in this setting. Cholesytramine is a bile salt binding resin that has value in the management of postcholecystectomy diarrhea.

Q1. A 25-year-old woman presents with postprandial regurgitation, typically after dinner. She initially had both heartburn and regurgitation. After she started esomeprazole 40 mg once a day 8 weeks ago, her heartburn completely resolved. An upper endoscopy, performed due to ongoing regurgitation symptoms, reveals a normal esophagus, and a 2-cm sliding hiatal hernia.
