DAPSONE vs NITROFURAZONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dapsone is a sulfone antibiotic that inhibits bacterial synthesis of dihydrofolic acid via competition with para-aminobenzoic acid for the active site of dihydropteroate synthase. It also has anti-inflammatory and immunomodulatory properties, including inhibition of neutrophil myeloperoxidase and suppression of neutrophil chemotaxis.
Nitrofurazone is a nitrofuran antibacterial agent that acts by inhibiting bacterial DNA synthesis and repair through reductive activation of the nitrofuran group. It disrupts bacterial enzymes involved in carbohydrate metabolism and inhibits acetylcoenzyme A formation.
100 mg orally once daily for leprosy or dermatitis herpetiformis.
Nitrofurazone is not systemically administered; it is used topically. For topical application, apply a thin layer to the affected area 1-2 times daily, as directed by a physician.

Clinical Note
moderateDapsone + Teriflunomide
"The metabolism of Teriflunomide can be decreased when combined with Dapsone."
Clinical Note
moderateDapsone + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Dapsone."
Clinical Note
moderateDapsone + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Dapsone."
Clinical Note
moderateDapsone + Erythromycin
Terminal elimination half-life is 20-30 hours (mean 28 hours). In patients with renal impairment, half-life may be prolonged up to 48 hours.
0.3–0.5 hours (rapid metabolism and excretion; clinically short duration requires frequent dosing for local infections).
Primarily renal (70-85% as metabolites, <20% unchanged). Biliary/fecal excretion accounts for 10-15%.
Renal: ~80% (glomerular filtration and tubular secretion); Fecal: ~10% (biliary excretion); Hepatic metabolism: ~10%.
