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).
An active site is the part of an enzyme that directly binds to a substrate and carries a reaction. It contains catalytic groups which are amino acids that promote formation and degradation of bonds. The inhibitor has an affinity for the active site of an enzyme where the substrate also binds to. 2  This type of inhibition can be overcome by increasing the concentrations of substrate, out-competing the inhibitor. 3  Competitive inhibitors are often similar in structure to the real substrate.
