L-Thyroxine (CAS: 51-48-9) kapena Levothyroxine ndi mahomoni opangidwa ndi chithokomiro omwe ali ofanana ndi thyroxine (T4), omwe mwachibadwa amapangidwa ndi maselo a follicular a chithokomiro.Amagwiritsidwa ntchito pochiza kuchepa kwa mahomoni a chithokomiro, komanso nthawi zina kuti apewe kuyambiranso kwa khansa ya chithokomiro.Monga mnzake wobisika mwachilengedwe, Levothyroxine ndi chiral mu mawonekedwe a L.Mankhwala okhudzana ndi dextrothyroxine (D-Thyroxine) adagwiritsidwa ntchito m'mbuyomu ngati chithandizo cha hypercholesterolemia (ma cholesterol okwera) koma adachotsedwa chifukwa cha zotsatira za mtima.L-Thyroxine makamaka ntchito zochizira hypothyroidism, goiter, aakulu lymphocytic thyroiditis, myxedema chikomokere, ndi stupor.Mu vivo, L-Thyroxine (0.9 ndi 2.7 μg) imalepheretsa kaphatikizidwe ndi kutulutsidwa kwa thyrotropin yopangidwa ndi thyrotropin-release hormone kuchokera ku anterior pituitary mu mbewa.Mapangidwe okhala ndi L-Thyroxine amagwiritsidwa ntchito pochiza hypothyroidism.Thandizo la Levothyroxine limagwiritsidwa ntchito ngati kuperewera kwa mahomoni a chithokomiro m'thupi la munthu, chifukwa zimachitika chifukwa cha kuchepa kwa chithokomiro, pituitary ndi hypothalamic glands (motsatana, primary, secondary and tertiary hypothyroidism).L-Thyroxine amagwiritsidwanso ntchito pochiza euthyroid goiter ndi multinodular goiter, kuphatikiza tinthu tating'onoting'ono ta chithokomiro, subacute kapena chronic thyroiditis, kapena pakapanda opaleshoni, kapena pambuyo pa chithandizo cha radiometabolic kwa odwala omwe ali ndi khansa ya chithokomiro.Zotsatira za mankhwalawa zimadalira kwambiri mlingo.Mlingo wocheperako, L-Thyroxine imawonetsa zochita za anabolic.Mlingo wapakatikati, umathandizira kukula ndikukula kwa minofu, kagayidwe ka mapuloteni, mafuta ndi chakudya, kumawonjezera magwiridwe antchito apakati pamanjenje ndi mtima, komanso impso ndi chiwindi.Mlingo waukulu, umachepetsa ntchito ya thyrotropic ya hypophysis ndikupondereza kupanga chithokomiro.
