Summary of Clinical Use Click here for help
Sulfacetamide sodium is authorised by the US FDA as an ophthalmic preparation to treat eye infections (Bleph-10®) and as a treatment for acne vulgaris (Klaron®), with generic formulations available. The compound was also available in combination with prednisolone sodium phosphate and with sulfathiazole + sulfabenzamide but these are now discontinued. The drug is not approved by the EMA, but individual European agencies have authorised its use.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Sulfonamides are structural analogues of 4-aminobenzoic acid (pABA) an intermediate in the de novo synthesis of folate by some prokaryotes, lower eukaryotes and plants [2]. The antibacterial MMOA is competitive inhibition of bacterial dihydropteroate synthase (DHPS) resulting in a block of folate biosynthesis [1].
