How does dapsone work for leprosy?
Dapsone works by preventing the bacteria from producing folate. Without folate, the bacteria cannot produce DNA and so are unable to increase in numbers. Dapsone therefore stops the spread of infection with Mycobacterium leprae. The remaining bacteria are killed by the immune system or eventually die.
What is dapsone used to treat?

Which form of leprosy is dapsone used to treat?

How does dapsone topical work?
Dapsone topical is used to treat acne in children, teenagers, and adults. Dapsone is in a class of medications called sulfone antibiotics. It works by slowing or stopping the growth of bacteria and to decrease inflammation.
Does dapsone cure leprosy?
Dapsone is an antibacterial medicine. It is prescribed for the treatment of two completely different conditions – a disease called leprosy, and a skin condition called dermatitis herpetiformis.
How does dapsone work for vasculitis?
Although it is not considered a standard treatment for IgA vasculitis, purpuric rash, abdominal pain, and arthritis in IgA vasculitis respond to it [7]. Dapsone, known as an antileprosy drug, has antioxidant scavenger effects and may suppress the production of toxic free radicals by neutrophils.
What is the mechanism of action of dapsone?
As an antimicrobial agent, dapsone is bacteriostatic in action. It inhibits the synthesis of dihydrofolic acid through by competing with para-aminobenzoic acid for the active site of dihydropteroate synthetase [35, 41], thus resembling the action of sulphonamides.
How does dapsone treat dermatitis herpetiformis?
Dapsone (diaminodiphenyl sulfone) and sulfapyridine (no longer available in most countries) are the primary medications used to treat dermatitis herpetiformis. The exact mechanism of action is unknown but is thought to be related to inhibition of neutrophil migration and function.
Which drug therapy is used in leprosy?
Rifampicin, the most important antileprosy medicine, is included in the treatment of both types of leprosy.
Is dapsone used to treat vasculitis?

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.
What are the modes of action for leprosy drugs?
The modes of action for most of the effective classes of drugs against M. leprae occur at the level of nucleic acid and protein synthesis. However, for many anti-leprosy drugs, the actual mechanisms of action are not known but inferred from studies of M. tuberculosis.
What was the first drug used to treat leprosy?
However, for many anti-leprosy drugs, the actual mechanisms of action are not known but inferred from studies of M. tuberculosis. The first effective treatment for leprosy was promin, a sodium glucosulfone (diamino-azobenzene 4’-sulfonamide) introduced in 1943 [13].
How does dapsone work against bacteria and protozoa?
Dapsone acts against bacteria and protozoa in the same way as sulphonamides, that is by inhibiting the synthesis of dihydrofolic acid through competition with para-amino-benzoate for the active site of dihydropteroate synthetase. The anti-inflammatory action of the drug is unrelated to its antibacterial action and is still not fully understood.
