DRUG DESCRIPTION. The active ingredient in PEPCIDÂ® (famotidine) is a histamine H2-receptor antagonist. Famotidine is N'(aminosulfonyl)-3-[[[2-[(diaminomethylene)amino]-4-thiazolyl]methyl]thio]propanimidamide. The empirical formula of famotidine is C 8 H 15 N 7 O 2 S 3 and its molecular weight is 337.43.Its structural formula is:top using famotidine and call your doctor at once if you have a serious side effect such as: 1  easy bruising or bleeding; 2  fast or pounding heartbeat; 3  confusion, hallucinations, seizure; 4  numbness or tingly feeling; or. 5  jaundice (yellowing of the skin or eyes).
The H2 blockers are specific antagonists of the histamine type 2 receptor, which is found on the basolateral (antiluminal) membrane of gastric parietal cells. The binding of famotidine to the H2 receptor results in inhibition of acid production and secretion, and improvement in symptoms and signs of acid-peptic disease.
