(also known as Thyrax, Euthyrox, Levaxin, Eltroxin, Levothyroxine, L-thyroxine, Synthetic T4, Levothroid, Levoxyl)
Levothyroxine is a synthetic form of thyroxine (thyroid hormone). As the hormone is chemically in the L-form (instead of D, see chirality), it is metabolised much slower than physiological thyroid hormone, which has a shorter half-life. more at Wikipedia
