[Pharmacology and Toxicology]
This product is a histamine H2 receptor blocker. It has a significant inhibitory effect on gastric acid secretion and may also inhibit the secretion of pepsin, showing some protective effects against experimental ulcers in animals. The onset of action is approximately one hour after administration, and the effect lasts for more than 12 hours.
[Pharmacokinetics]
Following oral administration, 14C-famotidine is rapidly absorbed in healthy volunteers in China, reaching peak blood concentrations in approximately 2 hours and a half-life of approximately 3 hours. Literature reports indicate that after oral or intravenous administration of 14C-famotidine to rats, radioactivity is elevated in the digestive tract, liver, kidneys, submandibular gland, and pancreas. 80% of the unchanged substance is excreted in the urine, and the inhibitory effect on hepatic enzymes is minimal.
