The relative bioavailability of 2 prototype fixed-dose combination formulations for amlodipine and rosuvastatin in healthy white and Chinese subjects.

摘要

A fixed-dose combination (FDC) may improve patient compliance and clinical outcomes in the management of cardiovascular risk in hypertensive and dyslipidemic patients. The study (NCT02075619) evaluated the bioavailability of 2 prototype FDC tablet formulations (FDC1 and FDC2) of amlodipine/rosuvastatin (10?mg/20?mg) compared with coadministered reference tablets. It was a randomized, single-dose, 3-way crossover pilot study in healthy white (n?=?12) and Chinese (n?=?12) adults. Three treatments (FDC1, FDC2, and reference) were administered after fasting with a washout period of 12-17 days. The pharmacokinetics of amlodipine and rosuvastatin were studied for all subjects (pooled) and by ethnicity. Safety and tolerability were also evaluated. Both FDCs met the bioequivalence criteria (90% confidence intervals falling within the range of 0.80-1.25) for AUC0-t and Cmax for amlodipine and rosuvastatin. Intrasubject variability (AUC0-t and Cmax ) was in the region of 23%-25% for rosuvastatin and 7%-10% for amlodipine. The FDC formulations demonstrated similar bioavailability to coadministered commercially available amlodipine and rosuvastatin. All treatments were generally well tolerated.
