Inhibition of prostacyclin and thromboxane biosynthesis in healthy volunteers by single and multiple doses of acetaminophen and indomethacin.

This double-blind, randomized crossover study assessed the effect of acetaminophen (1000 mg every 8 hours) versus indomethacin (50 mg every 8 hours) versus placebo on cyclooxygenase enzymes (COX-1 and COX-2). Urinary excretion of 2,3-dinor-6-keto-PGF1α, (prostacyclin metabolite, PGI-M; COX-2 inhibition) and 11-dehydro thromboxane B2 (thromboxane metabolite, Tx-M; COX-1 inhibition) were measured after 1 dose and 5 days of dosing. Peak inhibition of urinary metabolite excretion across 8 hours following dosing was the primary end point.

Effects of coadministered ezetimibe plus fenofibrate in mixed dyslipidemic patients with metabolic syndrome.

Objective: Patients with metabolic syndrome are at increased risk of atherosclerotic coronary heart disease, often have mixed dyslipidemia, and may thus require more aggressive treatment of multiple lipid parameters. The objective of this investigation was to compare the treatment response of ezetimibe co-administered with fenofibrate in mixed dyslipidemic patients with and without metabolic syndrome.

Methods: This post hoc analysis evaluated 625 patients 18-75 years of age with mixed dyslipidemia, defined as elevated low-density lipoprotein cholesterol (LDL-C) levels (130-220 mg/dL) and elevated triglycerides (TG) levels (200-500 mg/dL).

VAP II analysis of lipoprotein subclasses in mixed hyperlipidemic patients on treatment with ezetimibe/simvastatin and fenofibrate.

This analysis evaluates the effects on lipoprotein subfractions and LDL particle size of ezetimibe/simvastatin with or without coadministration of fenofibrate in patients with mixed hyperlipidemia. This multicenter, double-blind, placebo-controlled, parallel-group study included 611 patients aged 18-79 years randomized in 1:3:3:3 ratios to one of four 12 week treatment groups: placebo; ezetimibe/simvastatin 10/20 mg/day; fenofibrate 160 mg/day; or ezetimibe/simvastatin 10/20 mg/day + fenofibrate 160 mg/day. At baseline and study endpoint, cholesterol associated with VLDL, intermediate density lipoprotein (IDL), LDL, and HDL subfractions was quantified using the Vertical Auto Profile II method.
