H2-receptor antagonists

Receptors for H2 are located on the acid-producing parietal cells. Blocking histamine action suppresses gastric acid secretion.

Ranitidine (Zantac)

H2 antagonists prescribed for 8 wk, when most non– H pylori -associated ulcers heal. H2 blockers have no antibacterial effect; therefore, must be used with antibiotics to eradicate H pylori. Available as syr 15 mg/mL, tab 75, 150, or 300 mg; and effervescent tab 150 mg.
