tcsc2293 Ranitidine (hydrochloride)

Ranitidine is a histamine H2-receptor antagonist that inhibits stomach acid production.

Target: Histamine H2-Receptor

Ranitidine (Zantac) is a histamine H2-receptor antagonist with IC50 of 3.3 ± 1.4 uM. It inhibits stomach acid production. It is also used alongside fexofenadine and other antihistamines for the treatment of skin conditions such as hives. It has 10% the affinity that cimetidine has to CYP450 so it causes fewer side effects, but other H2 blockers famotidine and nizatidine have no CYP450 significant interactions [1, 2].
