Medication Summary
Medical therapy is aimed at control of gastric acid hypersecretion.
Proton pump inhibitors
Class Summary
Drugs of choice in ZES. Inhibit gastric acid secretion by inhibition of the H+/K+/ATP-ase enzyme system in the gastric parietal cells.
Omeprazole (Prilosec)
Decreases gastric acid secretion by inhibiting parietal cell H+/K+ ATP pump. Aim of therapy is to maintain BAO < 10 mmol 1 h prior to next dose.
Lansoprazole (Prevacid)
Decreases gastric acid secretion by inhibiting parietal cell H+/K+ ATP pump. Aim of therapy is to maintain BAO < 10 mmol 1 h prior to next dose.
Pantoprazole (Protonix)
Decreases gastric acid secretion by inhibiting parietal cell H+/K+ ATP pump. Aim of therapy is to maintain BAO < 10 mmol 1 h prior to next dose.
Esomeprazole magnesium (Nexium)
S-isomer of omeprazole used for symptomatic GERD. Inhibits gastric acid secretion by inhibiting H+/K+ ATP pump at secretory surface of gastric parietal cells.
Rabeprazole sodium (Aciphex)
Decreases gastric acid secretion by inhibiting the parietal cell H+/K+ ATP pump. For short-term (4-8 wk) treatment and relief of symptomatic erosive or ulcerative GERD. In patients not healed after 8 wk, consider additional 8-wk course.
