Iyini i-Methotrexate?
I-Methotrexate izwela i-hydrolysis, i-oxidation nokukhanya.Ayincibiliki emanzini.I-Methotrexate ibola ezimweni ezine-asidi kakhulu noma ezine-alkali.I-Methotrexate ayihambisani nama-oxidizing agents aqinile nama-acids aqinile.
I-Methotrexate isidakamizwa esisetshenziselwa ukwelapha umdlavuza, owaziwa nangokuthi izidakamizwa ze-cytotoxic.Ukuze unciphise i-cytotoxicity, ingasetshenziswa kanye ne-calcium leucovorin.Ngokuyinhloko isetshenziselwa ukwelapha i-acute leukemia (i-acute lymphocytic leukemia), umdlavuza webele, imvukuzane eyingozi kanye ne-choriocarcinoma, umdlavuza wekhanda nentamo, umdlavuza wamathambo, i-leukemia, ukungena kwe-meningeal yomgogodla, umdlavuza wamaphaphu, umdlavuza wesistimu yokuzala, umdlavuza wesibindi, i-refractory. i-psoriasis vulgaris, i-dermatomyositis, i-myositis yomzimba, ukuvuvukala kwe-spondylitis ankylosing, isifo sika-Crohn, i-psoriasis ne-psoriatic arthritis, isifo sikaBehcet kanye nesifo sokuzivikela komzimba.I-Methotrexate iyi-immuno suppressant futhi ingasetshenziselwa ukunciphisa inqubo ye-rheumatism ngempumelelo enhle kakhulu ekwelapheni ukuvuvukala kwe-synovial kwe-rheumatoid arthritis futhi iyimithi esetshenziswa kakhulu ukwelapha izifo ze-rheumatoid.
Isicelo somtholampilo
Isebenza ngempumelelo ekwelapheni i-acute leukemia ngokusebenza kangcono ezigulini zezingane.Isebenza kahle ekwelapheni i-choriocarcinoma kanye nemvukuzane eyingozi.Ukuphatha umthamo omkhulu kusebenza ngempumelelo ekwelapheni i-osteosarcoma, i-sarcoma yezicubu ezithambile, umdlavuza wamaphaphu, umdlavuza wamasende, umdlavuza webele, nomdlavuza wesibeletho.Iyasebenza futhi ekwelapheni umdlavuza wekhanda nentamo, umdlavuza wesibindi kanye nomdlavuza wamathumbu.I-Arterial infusion yalo mkhiqizo inamandla e-goo ekwelapheni umdlavuza wekhanda nentamo kanye nomdlavuza wesibindi.Kodwa-ke, akuvamile ukusetshenziselwa ukwelapha i-psoriasis ne-psoriasis.
