- © 2022, The American College of Clinical PharmacologyHypertension and hyperlipidemia are often comorbid, requiring combination therapies of antihypertensive drugs and antihyperlipidemia drugs. Taking 1 fixed-dose combination (FDC) may increase patient compliance rather than taking each of the drugs separately. This study aimed to evaluate the pharmacokinetic bioequivalence between an FDC of pitavastatin/valsartan 4/160 mg and the corresponding individual components. Considering that valsartan is a highly variable drug for maximum plasma concentration (Cmax), an open-label, randomized, partial replicated crossover study was conducted in 54 healthy subjects. The subjects received a single oral dose of the FDC of pitavastatin/valsartan 4/160 mg in 1 period or the corresponding individual components in the other 2 periods. The geometric mean ratios and their 90%CIs of the FDC to the corresponding individual components for Cmax and area under the concentration-time curve from time 0 to the last measurable time point were 1.05 (90%CI, 0.96-1.15) and 0.10 (90%CI, 0.95-1.04) for pitavastatin and 1.15 (90%CI, 1.06-1.25) and 1.06 (0.99-1.14) for valsartan, respectively. The geometric mean ratios (90%CIs) for area under the concentration-time curve from time 0 to the last measurable time point and Cmax of both drugs were included in the bioequivalence criteria. In conclusion, the FDC of pitavastatin/valsartan 4/160 mg showed pharmacokinetic equivalence with the corresponding individual components.
