Insulin glargine is a long-acting human insulin analog produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli (K12) as the production organism. Insulin glargine differs from human insulin in that the amino acid asparagine at position A21 is replaced by glycine and two arginines are added to the C-terminus of the B-chain. Chemically, insulin glargine is 21 A -Gly-30 B -a-L-Arg-30 B b-L-Arg-human insulin and has the empirical formula C 267 H 404 N 72 O 78 S 6 and a molecular weight of 6.063 kDa. Insulin glargine has the following structural formula: BASAGLAR (insulin glargine) injection is a sterile clear and colorless aqueous solution for subcutaneous use. Each mL contains 100 units of insulin glargine (3.6378 mg). The 3 mL BASAGLAR prefilled pen presentations contain the following inactive ingredients per mL: glycerin (17 mg), metacresol (2.7 mg), zinc oxide (content adjusted to provide 30 mcg zinc ion), and Water for Injection, USP. The pH is adjusted by addition of aqueous solutions of hydrochloric acid 10% and/or sodium hydroxide 10%. BASAGLAR has a pH of approximately 4. Structural Formula
