Insulin degludec is a long-acting basal human insulin analog for subcutaneous injection produced by a process that includes expression of recombinant DNA in Saccharomyces cerevisiae followed by chemical modification. Insulin degludec differs from human insulin in that the amino acid threonine in position B30 has been omitted and a side-chain consisting of glutamic acid and a C16 fatty acid has been attached (chemical name: LysB29(Nε-hexadecandioyl-γ-Glu) des(B30) human insulin). Insulin degludec has a molecular formula of C 274 H 411 N 65 O 81 S 6 and a molecular weight of 6.104 kDa. It has the following structure: Figure 1: Structural Formula of Insulin Degludec Insulin Degludec injection is a sterile, aqueous, clear, and colorless solution available as 100 units/mL (U-100) or 200 units/mL (U-200) for subcutaneous use. For the 100 units/mL solution, each mL contains 100 units of insulin degludec and glycerin (19.6 mg), metacresol (1.72 mg), phenol (1.5 mg), zinc (32.7 mcg), and Water for Injection, USP. For the 200 units/mL solution, each mL contains 200 units of insulin degludec and glycerin (19.6 mg), metacresol (1.72 mg), phenol (1.5 mg), zinc (71.9 mcg), and Water for Injection, USP. Insulin Degludec has a pH of approximately 7.6. Hydrochloric acid or sodium hydroxide may be added to adjust pH. Figure 1: Structural Formula of Tresiba
