NCIt definition : The dextrorotary isomer of thyroxine, a thyroid hormone with antihyperlipidemic activity.
Dextrothyroxine stimulates the formation of low-density lipoprotein (LDL) and increases
the catabolism of LDL thereby leading to increased excretion of cholesterol and bile
acids via the biliary route. This results in a reduction in serum cholesterol and
LDL.;
