TRESIBA is indicated to improve glycemic control in adults with diabetes mellitus.
Limitations of Use
TRESIBA is not recommended for the treatment of diabetic ketoacidosis.
TRESIBA (insulin degludec injection) is a long-acting basal human insulin analog for subcutaneous injection. Insulin degludec is 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 C274H411N65O81S6 and a molecular weight of 6103.97. It has the following structure:
