Argatroban is a synthetic direct thrombin inhibitor and the chemical name is 1-[5-[(aminoiminomethyl)amino]-1-oxo-2-[[(1,2,3,4-tetrahydro-3-methyl-8- quinolinyl)sulfonyl]amino]pentyl]-4-methyl-2-piperidinecarboxylic acid, monohydrate. Argatroban has 4 asymmetric carbons. One of the asymmetric carbons has an R configuration (stereoisomer Type I) and an S configuration (stereoisomer Type II). Argatroban consists of a mixture of R and S stereoisomers at a ratio of approximately 65:35. The molecular formula of argatroban is C 23 H 36 N 6 O 5 S•H 2 O. Its molecular weight is 526.66 g/mol. The structural formula is shown below: Argatroban is a white, odorless crystalline powder that is freely soluble in glacial acetic acid, slightly soluble in ethanol, and insoluble in acetone, ethyl acetate, and ether. Argatroban Injection 250 mg/2.5 mL (100 mg/mL) is a sterile clear, colorless to pale yellow, slightly viscous solution. Argatroban Injection 250 mg/2.5 mL (100 mg/mL) is available in 250-mg (in 2.5-mL) single-dose amber vials, with white flip-top caps. Each mL of sterile, nonpyrogenic solution contains 100 mg Argatroban. Inert ingredients (per vial): 1300 mg Propylene glycol, 760 mg Dehydrated alcohol. Arg chem structure
