Medical therapy for gastroesophageal reflux disease.
Gastroesophageal reflux disease (GERD) remains a ubiquitous problem, although therapeutic options continue to evolve. Effective therapy calls for understanding the pathogenesis. Key factors associated with GERD include incompetence of the lower esophageal sphincter, esophageal clearance, gastric contents, tissue resistance, and potency of the refluxate. Phase-type directed therapy remains the best treatment approach and histamine (H2)-receptor antagonists are now the cornerstone of therapy for patients not responsive to conservative measures. In a subset of patients with severe esophagitis who do not respond to conventional H2-receptor antagonist therapy, efficacy has been demonstrated with high-dose therapy. The acid suppressant omeprazole, highly effective in erosive esophagitis, is the drug of choice for esophagitis resistant to H2-receptor antagonists. Despite effective forms of therapy, relapse rates are high in patients with severe GERD, and maintenance therapy typically is required. With near uniformity, efficacy end points for these agents have been directed toward relief of heartburn, regurgitation, and dyspepsia. Few data exist correlating relief of GERD and improvement of chest pain. Although therapeutic strategies for treating GERD have improved, empiric treatment of suspected GERD in the patient with noncardiac chest pain does not appear to be the optimal approach and should be reserved for cases where diagnostic testing is limited or unavailable.
