Eptifibatide is a cyclic heptapeptide containing 6 amino acids and 1 mercaptopropionyl (des-amino cysteinyl) residue. An interchain disulfide bridge is formed between the cysteine amide and the mercaptopropionyl moieties. Chemically it is N 6 -(aminoiminomethyl)-N 2 -(3-mercapto-1-oxopropyl)-L-lysylglycyl-L-α-aspartyl-L-tryptophyl-L-prolyl-L-cysteinamide, cyclic (1→6)-disulfide. Eptifibatide binds to the platelet receptor glycoprotein (GP) IIb/IIIa of human platelets and inhibits platelet aggregation. The eptifibatide peptide is produced by solution-phase peptide synthesis, and is purified by preparative reverse-phase liquid chromatography and lyophilized. Eptifibatide is a white to off-white powder. The structural formula is: Eptifibatide injection is a clear, colorless, sterile, non-pyrogenic solution free from visible particles for intravenous (I.V.) use with a molecular formula of C 35 H 49 N 11 O 9 S 2 and a molecular weight of 831.96. Each 10 mL vial contains 2 mg/mL of eptifibatide and each 100 mL vial contains either 0.75 mg/mL of eptifibatide or 2 mg/mL of eptifibatide. Each vial of either size also contains 5.25 mg/mL citric acid and sodium hydroxide to adjust the pH to 5.35. Eptifibatide Chemical Structure
