Dosage-
Initially- 1 50mg tab twice daily Max daily dose of Sitalgliptin 100mg
Patients below 18 years not recommended
Pharmacology/ Pharmacokinetics:
Pharmacokinetics-
After oral admin of a 100mg dose to healthy subjects, sitagliptin was rapidly absorbed with
peak plasma concentration (median time to reach maximum concentration) occuring in
1 to 4 hours postdose.
Plasma area under the curve AUC of sitagliptin increased in a dose dependent manner.
Following a single 100mg dose to healthy volunteers , mean AUC of stagliptin was 8.52 M*h
maximum effective plasma concentration Cmax was 950 nM
Apparent terminal half life t 1/2 was 2.4 hrs
Plasma AUC of sitagliptin increased approx 14% following 100mg doses at steady state
compared with first dose. The intra and intersubject coefficients of variation for
sitagliptin AUC were small (5.8% and 15.1%)
