Choloxin
Dextrothyroxine
Chemical compound
Dextrothyroxine (trade name Choloxin) is a dextrorotary isomer of thyroxine.[1] It saw research as a cholesterol-lowering drug[2] but was pulled due to cardiac side-effects. It increases hepatic lipase which in turn improves utilization of triglycerides and decreases levels of lipoprotein(a) in blood serum.[3]
