I-Dapsone (4,4 -sulfonylbisbenzeneamine; 4,4 -sulfonyldianiline;p,p -diaminodiphenylsulfone; okanye iDDS [Avlosulfon]) iyenzeka njengomgubo ongenavumba, omhlophe oyikristale onyibilikayo kancinane kakhulu emanzini kwaye unyibilika kancinci etywaleni. ukukhanya okuzinzileyo, kodwa imikhondo yokungcola, kuqukwa namanzi, iyenza ibe ne-photosensitive kwaye ichaphazeleke ekukhanyeni. Nangona kungekho tshintsho lwekhemikhali lunokubonwa emva kokuguquka kombala, iyeza kufuneka likhuselwe ekukhanyeni. I-Dapsone isetyenziselwa ukunyanga zombini iintlobo zeqhenqa kunye ne-tuberculoid yeqhenqa. I-Dapsone isetyenziswa ngokubanzi kuzo zonke iintlobo zeqhenqa, rhoqo zidityaniswa ne-clofazimine andrifampin. Unyango lokuqala luhlala lubandakanya i-rifampin ene-dapsone, ilandelwa yi-dapsone iyodwa. Ikwasetyenziselwa ukunqanda ukwenzeka kweqhenqa le-multibacillary xa inikwe iprophylactically.I-Dapsone ikwalichiza elikhethwayo kwi-dermatitis herpetiformisand ngamanye amaxesha isetyenziswa nepyrimethamine kunyango lwemalariya kunye ne-trimethoprim yePCP. Iziphumo ebezingalindelekanga ezimandundu zinokubandakanya i-anemia ye-hemolytic, i-methemoglobinemia, kunye neziphumo eziyityhefu ze-hepatic. Iziphumo zeHemolytic zingachazwa kwizigulane ezine-glucose-6-phosphatedehydrogenase deficiency. Ngexesha lonyango, zonke izigulana zifuna ukubalwa kwegazi rhoqo. I-Dapsone ivunyiwe kunyango lwe-autoimmune blistering skin disease, i-dermatitis herpetiformis. Oku kuqhuma kakhulu kwe-pruritic kubonakala ngokwe-histologically ngokungena kwedermal exineneyo ye-neutrophils kunye namadyunguza angaphantsi kwe-subepidermal. Ezinye izifo zesikhumba apho i-dapsone iluncedo yi-linear immunoglobulin A (IgA) i-dermatosis, i-subcorneal pustular dermatosis, i-leukocytoclastic vasculitis, kunye neentlobo ezahlukeneyo zokuqhuma kwe-neutrophils, kubandakanywa nezinye iintlobo ze-lupus erythematosus.
