Lafutidine is a second generation of H2-receptor antagonist. H2-receptor antagonist can strongly inhibit gastric acid secretion compared with conventional drugs such as antacids. Unlike conventional H2-receptor antagonist, lafutidine inhibits gastric acid secretion during daytime as well as nighttime in clinical studies in humans. Lafutidine also has gastroprotective activity independent of its acid antisecretory efficacy, preventing noxious agent-induced gastric mucosal injury and accelerating the repair process following gastric mucosal damage. It also protects experimentally induced reflux esophagitis, indomethacin-induced intestinal, and dextran sulfate sodium-induced colonic inflammation.
Lafutidine is used for gastric and duodenal ulcers. It is also confirmed that lafutidine can be used as an empiric treatment and superior efficacy for primary care practice patients with dyspepsia.

Lafutidine is a histamine H2 receptor antagonist with gastroprotective activity. It inhibits histamine-induced cAMP production in CHO cells expressing human histamine H2 receptors when used at a concentration of 10 nM. Intragastric administration of lafutidine (3, 10, and 30 mg/kg) reduces hemorrhagic esophageal lesion size and gastric acid secretion in a rat model of pyloric ligation-induced reflux esophagitis. It prevents 5-fluorouracil-induced intestinal mucositis, diarrhea, and body weight loss in wild-type, but not Trpv1-/- or sensory deafferented, mice when administered at doses ranging from 3 to 30 mg/kg. Lafutidine (10 mg/kg) also reduces indomethacin-induced antral ulcer size in wild-type, but not chemically-deafferented, rats.
Lafutidine was launched in Japan for the treatment of gastritis, reflux oesophagitis and
peptic ulcers. It can be prepared in eight steps from 4-(2-tetrahydropyranyloxy)-2(Z)-butenl-
ol. Lafutidine is a potent and longer-acting H2 antagonist compared to other marketed
compounds of its class such as cimetidine and famotidine. In contrast to other
commercially available H2 antagonists, lafutidine also exerts a gastroprotective action
probably via capsaicin-sensitive afferent nerves. It was clinically effective in the treatment
of nonsteroidal antiinflammatory drug-induced ulcer in patients refractory to existing
antiulcer agents.
