🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine exerts its effects through a combination of antibacterial and anti-inflammatory actions. Dapsone inhibits the synthesis of dihydrofolic acid by competing with para-aminobenzoic acid (PABA) in bacteria, thereby inhibiting bacterial growth. Additionally, dapsone has anti-inflammatory properties that are not fully understood but are thought to involve inhibition of neutrophil chemotaxis, suppression of inflammatory cytokines, and inhibition of myeloperoxidase. When applied topically, it reduces the population of Propionibacterium acnes and diminishes the inflammatory response in acne lesions.
