Aims: To assess the effect of rosuvastatin on oestrogen and progestin pharmacokinetics in women taking a commonly prescribed combination oral contraceptive steroid (OCS); the effect on endogenous hormones and the lipid profile was also assessed.

Methods: This open-label, nonrandomised trial consisted of 2 sequential menstrual cycles. Eighteen healthy female volunteers received OCS (Ortho Tri-Cyclen) on Days 1-21 and placebo OCS on Days 22-28 of Cycles A and B Rosuvastatin 40 mg was also given on Days 1-21 of Cycle B.

Background: Rosuvastatin is a 3-hydroxy-3-methylglutaryl coenzyme A-reductase inhibitor, or statin, that has been developed for the treatment of dyslipidemia.

Objective: This study assessed the metabolism, excretion, and pharmacokinetics of a single oral dose of radiolabeled rosuvastatin ([14C]-rosuvastatin) in healthy volunteers.

Methods: This was a nonrandomized, open-label, single-day trial.

Background: Rosuvastatin is a 3-hydroxy-3-methylglutaryl coenzyme A-reductase inhibitor developed for the treatment of dyslipidemia. The results of clinical trials suggest that it is effective and well tolerated.

Objectives: The goals of this study were to determine the absolute bioavailability of an oral dose of rosuvastatin and to describe the intravenous pharmacokinetics of rosuvastatin in healthy volunteers.

Background: Rosuvastatin, a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor, has been developed for the treatment of patients with dyslipidemia.

Objective: This study assessed the dose proportionality and pharmacokinetics of single oral doses of rosuvastatin in healthy volunteers.

Methods: This was a double-blind, randomized, incomplete crossover trial consisting of 3 trial days separated by >/=7-day washout periods.

Background: Rosuvastatin is a new 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor. Itraconazole, an inhibitor of cytochrome P450 (CYP) 3A4 and the transport protein P-glycoprotein, is known to interact with other HMG-CoA reductase inhibitors. The current trials aimed to examine in vivo the effect of itraconazole on the pharmacokinetics of rosuvastatin.

Aims: To examine in vivo the effect of ketoconazole on the pharmacokinetics of rosuvastatin, a 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor.

Methods: This was a randomized, double-blind, two-way crossover, placebo-controlled trial. Healthy male volunteers (n = 14) received ketoconazole 200 mg or placebo twice daily for 7 days, and rosuvastatin 80 mg was coadministered on day 4 of dosing.

The effect of rosuvastatin on the pharmacokinetics of digoxin was assessed in 18 healthy male volunteers in this double-blind, randomized, two-way crossover trial. Volunteers were dosed with rosuvastatin (40 mg once daily) or placebo to steady state before being given a single dose of digoxin 0.5 mg.

The effects of age and gender on the pharmacokinetics of rosuvastatin (Crestor) were assessed in healthy young (18-35 years) and elderly (> 65 years) males and females in this open, nonrandomized, noncontrolled, parallel-group trial. Sixteen males and 16 females (8 young and elderly volunteers per gender group) were enrolled. Mean (range) ages were 24 (18-33) and 68 (65-73) years for young and elderly volunteers, respectively.
