Medical treatment of gastroesophageal reflux disease: options and priorities.
Gastroesophageal reflux disease (GERD) represents a spectra of symptoms and of reflux damage to the esophagus. This reflux damage is due to a prolonged acid exposure of the esophagus arising from an imbalance between protective motility factors and aggressive acid secretory factors. Initially, patients may be managed by modifying their food intake and by supportive anti-gravity measures. However, many individuals will require drug therapy. Symptomatic relief can be achieved with pro-kinetic agents, antacids, sucralfate suspension, H2-receptor antagonists and H(+)-K+ ATPase pump blockers. There are limitations in the study design of experiments which have compared one agent with another. Accepting these design limitations, it would appear that pump blockers lead to higher rates of endoscopic healing than the use of standard doses of H2-receptor antagonists. However, higher doses of H2-receptor antagonists will likely give higher rates of symptomatic relief and endoscopic healing of GERD. Recurrence of symptoms and esophagitis occur in a high proportion of patients with GERD, and some patients may need to be considered for maintenance therapy.
