Preventive Effects of Lansoprazole and Famotidine on Gastric Mucosal Injury Induced by Low-Dose Aspirin in Helicobacter pylori-Negative Healthy Volunteers.
Summary of "Preventive Effects of Lansoprazole and Famotidine on Gastric Mucosal Injury Induced by Low-Dose Aspirin in Helicobacter pylori-Negative Healthy Volunteers."
The preventive effects of lansoprazole and famotidine on low-dose aspirin-induced gastric mucosal injury in relation to gastric acidity were compared in healthy Japanese volunteers. Fifteen Helicobacter pylori-negative volunteers with different CYP2C19 genotypes were randomly administered aspirin 100 mg, aspirin plus famotidine 20 mg twice daily, or aspirin plus lansoprazole 15 mg once daily for 7 days each in a crossover fashion. Gastroscopy for the evaluation of mucosal injury based on modified Lanza score (MLS) and 24-hour intragastric pH monitoring were performed on day 7 of each regimen. Aspirin induced gastric mucosal injury (median MLS = 3). Lansoprazole significantly decreased MLS to 0, which was significantly lower than that by famotidine (MLS = 1) (P < .05). Medians of pH 3 holding time and mean 24-hour pH values with the lansoprazole regimen were significantly higher than those with famotidine (P < .05). No significant differences in MLS were observed among the different CYP2C19 genotype groups in any of the treatment regimens. In this 7-day study, lansoprazole appeared to be more protective than famotidine against low-dose aspirin-induced mucosal injury but a larger well-controlled study is necessary to establish a definitive clinical benefit.

Medical and Biotech [MESH] Definitions
A synthetic methylprostaglandin E1 analog that reduces gastric acid secretion and enhances the gastric mucus-bicarbonate barrier. It is effective in the therapy of gastric ulcers and gives significant protection against NSAID-induced gastric mucosal damage. The drug also prevents cyclosporin A-induced damage to endocrine and exocrine pancreatic secretions. It shows a low order of acute toxicity and there is no evidence of embryotoxicity, fetotoxicity, teratogenicity, or mutagenicity in animal studies.
A competitive histamine H2-receptor antagonist. Its main pharmacodynamic effect is the inhibition of gastric secretion.
A synthetic analog of natural prostaglandin E1. It produces a dose-related inhibition of gastric acid and pepsin secretion, and enhances mucosal resistance to injury. It is an effective anti-ulcer agent and also has oxytocic properties.
GASTRITIS with atrophy of the GASTRIC MUCOSA, the GASTRIC PARIETAL CELLS, and the mucosal glands leading to ACHLORHYDRIA. Atrophic gastritis usually progresses from chronic gastritis.
Nonsusceptibility to the pathogenic effects of foreign microorganisms or antigenic substances as a result of antibody secretions of the mucous membranes. Mucosal epithelia in the gastrointestinal, respiratory, and reproductive tracts produce a form of IgA (IMMUNOGLOBULIN A, SECRETORY) that serves to protect these ports of entry into the body.
