sulfacetamide sodium 

An anti-infective, bacteriostatic drug of the sulfonamide family, used topically against infections and injuries, as well as minor abrasions, of the conjunctiva and cornea. It should not be used immediately following a local anaesthetic. However, antibiotics (e.g. bacitracin, chloramphenicol, erythromycin, gentamicin, neomycin, norfloxacin, polymyxin B, tetracycline, tobramycin), which inhibit or destroy a wide range of microorganisms are used more commonly than local sulfonamides. See antibiotic; antifungal agent; antiinflammatory drug; bacteriostatic; sulfonamide.
