L-Thyroxine (CAS: 51-48-9) los yog Levothyroxine yog cov thyroid hormones hluavtaws uas yog tshuaj zoo ib yam rau thyroxine (T4), uas yog ib txwm zais los ntawm cov hlwb follicular ntawm cov thyroid caj pas.Nws yog siv los kho cov thyroid hormone deficiency, thiab qee zaus los tiv thaiv kev rov tshwm sim ntawm cov thyroid cancer.Ib yam li nws tus kheej zais cia, Levothyroxine yog ib qho chiral compound hauv L-daim ntawv.Cov tshuaj muaj feem xyuam nrog dextrothyroxine (D-Thyroxine) tau siv yav dhau los ua kev kho mob rau hypercholesterolemia (nce qib roj cholesterol) tab sis raug tshem tawm vim muaj kev mob plawv.L-Thyroxine tsuas yog siv rau kev kho mob hypothyroidism, goiter, mob lymphocytic thyroiditis, myxedema coma, thiab stupor.Hauv vivo, L-Thyroxine (0.9 thiab 2.7 μg) inhibits synthesis thiab tso tawm ntawm thyrotropin induced los ntawm thyrotropin-tso cov tshuaj hormones los ntawm anterior pituitary hauv cov nas.Cov tshuaj uas muaj L-Thyroxine tau siv los kho hypothyroidism.Levothyroxine therapy yog siv nyob rau hauv cov ntaub ntawv ntawm deficiency ntawm cov thyroid hormones nyob rau hauv tib neeg lub cev, raws li nws tshwm sim nyob rau hauv lub deficiency ntawm thyroid, pituitary thiab hypothalamic qog (feem ntau, theem nrab thiab tertiary hypothyroidism).L-Thyroxine kuj tseem siv rau hauv kev kho mob ntawm euthyroid goiter thiab multinodular goiter, nrog rau cov thyroid nodules, subacute los yog chronic thyroiditis, los yog nyob rau hauv cov ntaub ntawv ntawm ib tug tom qab phais tsis txaus, los yog tom qab kev kho mob radiometabolic nyob rau hauv cov neeg mob uas muaj thyroid cancer.Cov teebmeem ntawm cov tshuaj no nyob ntawm ntau npaum li cas.Hauv cov koob tshuaj me me, L-Thyroxine nthuav tawm cov tshuaj anabolic.Hauv cov koob tshuaj nruab nrab, nws txhawb kev loj hlob thiab kev loj hlob ntawm cov ntaub so ntswg, metabolism ntawm cov protein, rog, thiab carbohydrates, nce kev ua haujlwm ntawm lub hauv paus paj hlwb thiab cov hlab plawv, nrog rau ob lub raum thiab lub siab.Hauv cov koob tshuaj loj, nws ua rau qeeb ntawm thyrotropic kev ua ntawm hypophysis thiab inhibits cov thyroid caj pas.
