Pharmacokinetics and Pharmacodynamics of Twice Daily and Once Daily Regimens of Empagliflozin in Healthy Subjects
Abstract
PURPOSE: This study was undertaken to compare the steady-state pharmacokinetic and pharmacodynamic properties of empagliflozin 5 mg twice daily (BID) and 10 mg once daily (QD) in healthy subjects.
METHODS: In an open-label, 2-way crossover study, subjects (n = 16) received empagliflozin 5 mg BID for 5 days and empagliflozin 10 mg QD for 5 days in a randomized order, with a washout period of ≥6 days between each treatment. The primary objective was the comparison of the overall exposure during a 24-hour period at steady state (AUC0-24,ss) for empagliflozin, based on standard bioequivalence criteria, with BID and QD dose regimens.
FINDINGS: The study population comprised 7 (43.8%) men and 9 (56.3%) women with a baseline median age of 38.0 years (range, 23-47 years) and a median body mass index of 23.3 kg/m(2) (range, 19.8-27.8 kg/m(2)). Based on standard bioequivalence criteria, there was no difference in the overall exposure of empagliflozin between BID and QD dose regimens (geometric mean ratio of AUC0-24,ss for empagliflozin 5 mg BID compared with empagliflozin 10 mg QD = 99.36%; 90% CI, 94.29-104.71). For empagliflozin 10 mg QD, mean (%CV) AUC during the dosing interval was 1900 nmol · h/L (20.6%), mean (%CV) Cmax,ss was 330 nmol/L (25.3%), and median (range) Tmax,ss was 1.0 hour (0.7-2.0 hours). For empagliflozin 5 mg BID, mean (%CV) AUC during the dosing interval was 1010 nmol · h/L (15.1%) and 867 nmol · h/L (18.6%) after the morning and evening dose, respectively, mean…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 16 participants or records.
