Pharmacokinetic comparison using two tablets of an evogliptin/metformin XR 2.5/500 mg fixed dose combination vs. 1 tablet each of evogliptin 5 mg and metformin XR 1,000 mg .
Abstract
OBJECTIVES: The aim of this study was to compare the pharmacokinetic (PK) characteristics of evogliptin and metformin following the administration of 2 evogliptin/metformin extended-release (XR) 2.5/500 mg FDC tablets with the coadministration of separate evogliptin 5-mg and metformin XR 1,000-mg tablets (separate formulations).
METHODS: A randomized, two-period, two-sequence crossover study was conducted. Subjects were randomly assigned to receive 2 FDC tablets or the individual tablets, followed by a 14-day washout period and the administration of the alternate treatment. Blood samples were collected predose and up to 72 hours postdose for each period. PK parameters including Cmax and AUClast were calculated. The geometric mean ratios (GMRs) and the 90% confidence intervals (CIs) between FDC and the separate formulations were calculated for the Cmax and AUClast of evogliptin and metformin.
RESULTS: 33 subjects completed the study. The GMR (90% CI) values of Cmax and AUClast for evogliptin were 1.011 (0.959 - 1.066) and 1.010 (0.977 - 1.043), respectively. The GMR (90% CI) values of Cmax and AUClast for metformin were 0.892 (0.827 - 0.963) and 0.893 (0.841 - 0.947), respectively. There was no significant difference between the FDC and separate formulations regarding the occurrence of adverse events. All drug-related adverse events were considered to be mild and resolved without any treatment.
CONCLUSIONS: Two FDC tablets of evogliptin/metformin XR 2.5/500 mg showed a…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 33 participants or records.
