1.3.1 H2-receptor antagonists

General guidance

  • Histamine H2 receptor (H2RA) antagonists remain useful agents for some patients with mild to moderate GORD.
  • Cimetidine has several important drug interactions.
  • Significant numbers of patients remain on treatment doses of these agents without any apparent attempt to step down their therapy.
  • Planned step-down should be discussed with the patient upon initiation of treatment and should be carried out.
  • Gynaecomastia with cimetidine appears to be dose dependent. At the lower dose commonly used it is very rare.
  • Intravenous histamine H2-receptor antagonists are ineffective in acute ulceration and have been reported to increase infective complications. Therefore they should not be used in general hospital practice.
