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).
Famotidine, which also has been marketed the brand names - Pepcid and Pepcidine, works to inhibit the production of stomach acid. Another product called Pepcid Complete combines famotidine with an antacid to form a chewable tablet. Unlike other H2 antagomists like cimetidine, Famotidine does not have an effect on the cytochrome P450 enzyme system. H2 antagomists block the histamine receptors in the secretory cells of the stomach.
