Rosuvastatin pharmacokinetics in Pakistani healthy volunteers in comparison with other population..
Pak J Pharm Sci Jan ;32(6):2725-32.

In current study, the pharmacokinetics (PK) of rosuvastatin were evaluated in Pakistani healthy volunteers and compared with those reported in other population. This was a randomized and open labeled clinical trial in which a single oral dose of 40 mg rosuvastatin was administered to the overnight fasted healthy volunteers. Plasma concentrations of rosuvastatin were quantified by a validated liquid chromatography-tandem mass spectrometry method. The PK parameters of rosuvastatin and its metabolite N-desmethyl-rosuvastatin were determined by PK specific software i.e., PK-Summit® (PK-Solutions). A total of 20 healthy volunteers having BMI in the normal ranges were included in this study. All PK parameters were represented as mean ± SD and 95% confidence intervals of the means have been calculated. The Cmax (29.07 ± 6.88 ng/mL), [AUC] (206.65 ± 55.27 ng/hr/mL) and CL/F (3275.26 ± 1072.87 mL/hr) were slightly higher in our study, whereas the values of Vd (19377.23 ± 9114.29 mL) and t (3.0 ± 0.46 hr) were comparatively smaller. Overall, the PK parameters of rosuvastatin determined in our study were in compliance with other reported. Therefore, no adjustments in the dosing schedule or dose are warranted.
