Pharmacodynamics

Linagliptin is a competitive, reversible DPP-4 inhibitor. DPP-4, is an enzyme that degrades the incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). Inhibition of DPP-4 in turn, increases the plasma concentrations of active incretin hormones, thereby stimulating the release of insulin in a glucose-dependent manner and decreasing circulating levels of glucagon. GLP-1 and GIP are involved in the physiological regulation of glucose homeostasis. Both hormones increase the biosynthesis of insulin and its secretion from pancreatic beta cells in the presence of normal or elevated levels of blood glucose. In addition, GLP-1 reduces glucagon secretion from pancreatic alpha-cells, resulting in a reduction in glucose output in the liver

Pharmacokinetics

Absorption: Linagliptin is rapidly absorbed after oral administration, with C (max) occurring after approximately 90 minutes, and reaches steady-state concentrations within 4 days. The oral bioavailability of Linagliptin is approximately 30%.

Distribution: Linagliptin exhibits a V (d) of more than 1000 L, indicating widespread distribution into tissues. Binding to target proteins in plasma and peripheral tissues exerts a major influence upon broadening Linagliptin distribution.

Metabolism & Excretion: Linagliptin is hardly metabolized and approximately 90% of the compound is excreted in an unchanged form by the hepatobiliary route via the feces. 84.7% of Linagliptin is eliminated in the feces and 5.4% is eliminated in the urine.

Half Life: Linagliptin has a long terminal half-life (>100 hours); however, its accumulation half-life is much shorter (approximately 10 hours), accounting for the rapid attainment of steady state.

Indications

  • Indicated for adults with type 2 diabetes mellitus along with diet and exercise to lower blood sugar

WARNINGS AND PRECAUTIONS:
