Tidsramme |
|---|---|---|
|
Linagliptin: AUC_τ,ss
Tidsramme: 24 hours
|
area under the concentration time curve (AUC_τ) of linagliptin in plasma at steady state over a uniform dosing interval
|
24 hours
|
|
Linagliptin: C_max,ss
Tidsramme: 24 hours

|
DPP-4 Inhibition: E_24,ss
Tidsramme: One single measurement 24 h after drug administration under steady state conditions
|
Plasma DPP-4 inhibition at trough under steady state conditions.
Plasma DPP-4 inhibition is derived by calculating (1-(activity in presence of linagliptin)/baseline activity))*100%, where 'activity' is the activity of the DPP-IV enzyme.
