High-density Lipoprotein (HDL) Cholesterol in Women Taking Tibolone (TibFen)
|ClinicalTrials.gov Identifier: NCT00809068|
Recruitment Status : Completed
First Posted : December 16, 2008
Last Update Posted : February 2, 2010
Tibolone (Livial) has been shown in previous studies to lower HDL cholesterol by up to 40%.
This study aims to study the effects of fenofibrate on HDL and subfractions in women taking tibolone.
|Condition or disease||Intervention/treatment||Phase|
|HDL Cholesterol||Drug: fenofibrate and tibolone Drug: tibolone||Phase 4|
Tibolone decreases plasma concentrations of HDL cholesterol and HDL-apoA1 and pre-beta HDL, consistent with a pro-atherogenic effect. The mechanism of tibolone on HDL cholesterol has been suggested to result from an acceleration of the catabolism of HDL by stimulation of hepatic lipase with no effect on cellular cholesterol efflux.
PPAR-a agonists, in particular fenofibrate, improve HDL metabolism by increasing the expression and hepatic secretion of HDL apoAI and apoAII.
We hypothesise that fenofibrate will rectify the perturbations on HDL metabolism wrought by tibolone.
