藥動學
Pravastatin Onset of action: Several daysPeak effect: 4 weeksLDL-reduction: 40 mg/day: 34% (for each doubling of this dose, LDL-C is lowered by ~6%)Absorption: Rapidly absorbed; average absorption 34%Distribution: Vd: 0.46 L/kgProtein binding: ~50%Metabolism: Hepatic multiple metabolites; primary metabolite is 3 alpha-hydroxy-iso-pravastatin (2.5% to 10% activity of parent drug), 6-epi-pravastatin; extensive first-pass metabolism, isomerization, hydroxylation, oxidation and conjugationBioavailability: 17%Half-life elimination:Children and Adolescents (4.9 to 15.6 years): 1.6 hours; range: 0.85 to 4.2 hours (Hedman 2003)Clearance:0.81 l/h/kg; renal clearance:0.38l/h/kg secreted by renal tubuleAdults: 77 hours (including all metabolites); Pravastatin: ~2 to 3 hours (Pan 1990); 3 alpha-hydroxy-iso-pravastatin: ~1.5 hours (Gustavson 2005)Time to peak, serum: 1 to 1.5 hoursFenofibrateAbsorption: Increased when taken with mealsDistribution: Widely to most tissues,Vd: 30 LProtein binding: ~99%Metabolism: Fenofibrate is metabolized in the tissue and plasma via esterases to the active form, fenofibric acid; fenofibric acid then undergoes inactivation by glucuronidation hepatically or renallyBioavailability: Fenofibric acid: ~81%Half-life elimination: Fenofibric acid: Mean: 20 hours (range: 10 to 35 hours); half-life prolonged in patients with renal impairment; can not be eliminated by hemodialysisTime to peak: 2 to 8 hoursExcretion: Urine (~60% as metabolites); feces (25%); hemodialysis has no effect on removal of fenofibric acid from plasmaExcretion: Feces (70%); urine (~20%, 8% as unchanged drug)
