Cimetidine is a type of drug known as an antacid. Cimetidine works by binding to histamine H-2 receptors on various cells throughout the body, primarily in the stomach.
By blocking H-2 receptors, it prevents the secretion of gastric acid into the stomach. H-2 blockers do not bind to H-1 receptors, so they do not produce the same effects as antihistamines.
