DAPSONE vs FUROXONE
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.
Furazolidone is a nitrofuran antimicrobial that inhibits bacterial monoamine oxidase and disrupts bacterial DNA synthesis by undergoing reduction by bacterial nitroreductases to reactive intermediates that cause DNA cross-linking and damage.

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.
Terminal elimination half-life is approximately 1.5–2 hours; clinically, this supports dosing every 6 hours for sustained antibacterial effect.
Primarily renal (70-85% as metabolites, <20% unchanged). Biliary/fecal excretion accounts for 10-15%.
Primarily renal (approximately 65%) as unchanged drug; biliary/fecal excretion accounts for about 35%.
