Dextrothyroxine is the dextrorotary isomer of the synthetic thyroxine. It is an antihyperlipidemic agent. The mechanism of action is not completely understood, but dextrothyroxine apparently acts in the liver to stimulate formation of low-density lipoprotein (LDL) and, to a much greater extent, to increase catabolism of LDL. This leads to increased excretion of cholesterol and bile acids via the biliary route into the feces, with a resulting reduction in serum cholesterol and LDL. Dextrothyroxine has no significant effect on high-density lipoproteins (HDL). Inherently, it will also bind to thyroid receptors and as it is a prohormone, it will bind as a substrate to iodide peroxidase.

In Vitro Use Guide
The relative binding affinities of liothyronine (L-T3), levothyroxine (L-T4), D-triiodothyronine (D-T3), and dextrothyroxine (D-T4) were measured in vitro. Solubilized nuclear receptors were prepared from rat anterior pituitaries. L-T3 had the highest binding for the nuclear receptor (taken as 100%). L-T4 and D-T3 binded to the nuclear receptor with similar affinities (11% and 13%, respectively), while the affinity of D-T4 represents only 3% that of L-T3.
