Dapsone (C0010980)

Definition (CHV) a drug used to treat leprosy and skin infections
Definition (CHV) a drug used to treat leprosy and skin infections
Definition (CHV) a drug used to treat leprosy and skin infections
Definition (NCI) A synthetic derivative of diamino-sulfone with anti-inflammatory and anti-bacterial properties. As a structural analog of p-aminobenzoic acid (PABA), dapsone inhibits dihydropteroate synthase (DHPS), an enzyme important in folate synthesis, resulting in a depletion of the folate pool and a reduction in the amount of thymidylate available for DNA synthesis. Although the exact mechanism through which dapsone exerts its anti-inflammatory activity has yet to be fully elucidated, this agent interferes with the activation and oxidative damage of myeloperoxidase in neutrophils and inhibits the integrin-mediated adherence and chemotaxis of neutrophils. Dapsone's anti-inflammatory activities may contribute to the effects seen upon topical administration.
Definition (NCI_NCI-GLOSS) A drug used to treat acne. It is also used to treat other types of skin diseases and certain bacterial infections, such as leprosy. It blocks bacteria from making a substance that they need to grow. Dapsone is a type of antibacterial agent and a type of anti-inflammatory agent.
Definition (CSP) USP lists as a suppressant of dermatitis herpetiformis.
Definition (MSH) A sulfone active against a wide range of bacteria but mainly employed for its actions against MYCOBACTERIUM LEPRAE. Its mechanism of action is probably similar to that of the SULFONAMIDES which involves inhibition of folic acid synthesis in susceptible organisms. It is also used with PYRIMETHAMINE in the treatment of malaria. (From Martindale, The Extra Pharmacopoeia, 30th ed, p157-8)
Definition (PDQ) A synthetic derivative of diamino-sulfone with anti-mycobacterial and anti-malarial properties. A structural analog of p-aminobenzoic acid (PABA), dapsone inhibits dihydropteroate synthase (DHPS), an enzyme important in folate synthesis, resulting in a depletion of the folate pool and a reduction in the amount of thymidylate available for DNA synthesis.
