Halofenate

Halofenate, structurally akin to clofibrate, was evaluated in hypertriglyceridemic patients over 6-week periods in a controlled, double-blind crossover trial. It effectively reduced serum triglycerides by 50%, with minimal impact on serum cholesterol levels. Additionally, it lowered serum uric acid by 30% and exhibited uricosuric effects independent of glomerular filtration rate. Halofenate was associated with a significant increase in plasma thyroxine (T4), accompanied by a decrease in protein-bound iodine and T4 by column. In vitro studies confirmed its ability to displace T4 from thyroid-binding proteins, suggesting a thyroxine-displacing effect, which could influence thyroid function in vivo.
