Dapsone, also known as diaminodiphenyl sulfone (DDS), is an antibiotic commonly used in combination with rifampicin and clofazimine for the treatment of leprosy.〔(【引用サイトリンク】 url=http://www.drugs.com/monograph/dapsone.html )〕 It is a second-line medication for the treatment and prevention of Pneumocystis pneumonia and for the prevention of toxoplasmosis in those who have poor immune function.〔 Additionally, it has been used for acne as well as other skin conditions. Dapsone is available both topically and by mouth. Severe side effects may include: a decrease in blood cells, red blood cell breakdown especially in those with glucose-6-phosphate dehydrogenase deficiency (G-6-PD), or hypersensitivity.〔 Common side effects include nausea and loss of appetite.〔 Other side effects include liver inflammation and a number of types of skin rashes.〔 While it is not entirely clear the safety of use during pregnancy some physicians recommend that it be continued in those with leprosy.〔 It is of the sulfone class.〔 Dapsone was first studied as an antibiotic in 1937.〔 Its use for leprosy began in 1945.〔 It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system. The oral form is available as a generic drug and not very expensive.〔 == Medical uses == Dapsone is commonly used in combination with rifampicin and clofazimine for the treatment of leprosy.〔 It is used to both treat and prevent Pneumocystis pneumonia (PCP) and prevent toxoplasmosis in people unable to tolerate trimethoprim with sulfamethoxazole.〔 Dapsone may be used to treat brown recluse spider bites that become necrotic. It, along with a gluten free diet may also help with dermatitis herpetiformis.〔 Oral dapsone was one of the first medications used to treat moderate to severe acne vulgaris, and is still occasionally prescribed for the treatment of severe cases. A topical form of dapsone is also effective with potentially less side effects. It is unclear if the combination with pyrimethamine is useful in the prevention of malaria. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dapsone」の詳細全文を読む スポンサード リンク
