I-Dapsone (4,4 -sulfonylbisbenzeneamine; 4,4 -sulfonyldianiline;p,p -diaminodiphenylsulfone; noma i-DDS [Avlosulfon]) ivela njengempushana engenaphunga, eyikristale emhlophe encibilika kancane emanzini futhi incibilika kancane otshwaleni. ukukhanya okuzinzile, kodwa imikhondo yokungcola, okuhlanganisa namanzi, kuyenza ibe nezithombe futhi ngaleyo ndlela ibe lula ekushintsheni kombala ekukhanyeni. Nakuba lungekho ushintsho lwamakhemikhali olutholakalayo ngemva kokushintsha kombala, umuthi kufanele uvikelwe ekukhanyeni. I-Dapsone isetshenziswa ekwelapheni zombili izinhlobo zochoko ezinochoko kanye ne-tuberculoid. I-Dapsone isetshenziswa kabanzi kuzo zonke izinhlobo zochoko, ngokuvamile ihlanganiswe ne-clofazimine andrifampin. Ukwelashwa kokuqala kuvame ukufaka i-rifampin ene-dapsone, ilandelwe yi-dapsone iyodwa. Iphinde isetshenziselwe ukuvimbela ukwenzeka kochoko lwe-multibacillary uma inikezwa ngendlela yokuvimbela. I-Dapsone futhi iwumuthi okhethwayo we-dermatitis herpetiformisand ngezinye izikhathi isetshenziswa ne-pyrimethamine ekwelapheni umalaleveva kanye ne-trimethoprim ye-PCP. Imiphumela emibi kakhulu ingabandakanya i-hemolytic anemia, i-methemoglobinemia, nemiphumela enobuthi ye-hepatic. Imiphumela ye-Hemolytic ingavezwa ezigulini ezinokushoda kwe-glucose-6-phosphatedehydrogenase. Ngesikhathi sokwelashwa, zonke iziguli zidinga ukubalwa kwegazi njalo. I-Dapsone ivunyelwe ukwelashwa kwesifo sesikhumba esizimele, i-dermatitis herpetiformis. Lokhu kuqhuma okukhulu kwe-pruritic kubonakala ngokomlando ngokungena kwesikhumba esiminyene sama-neutrophils namabhamuza e-subepidermal. Ezinye izifo zesikhumba lapho i-dapsone isiza khona i-linear immunoglobulin A (IgA) dermatosis, i-subcorneal pustular dermatosis, i-leukocytoclastic vasculitis, kanye nokuqhuma okungavamile okungavamile lapho ama-neutrophils egcwele khona, kuhlanganise nezinye izinhlobo ze-cutaneous lupus erythematosus.
