The usual adult dosage is 20 mg of teneligliptin administered orally once daily. If efficacy is insufficient, the dose may be increased up to 40 mg once daily while closely monitoring the clinical course.

Human umbilical vein endothelial cells were cultured under normal (5 mmol/L) or high glucose level (25 mmol/L) during 21 days, or at high glucose during 14 days followed by 7 days at normal glucose, to reproduce the high-metabolic memory state. At this time, different concentrations of teneligliptin (0.1, 1.0 and 3.0 umol/L) were added to cells. Teneligliptin was shown to protect human umbilical vein endothelial cells from oxidative stress.
