APPLICATIONS
Sulfacetamide, a sulfa drug, has been used as an antimicrobial agent by inhibiting bacterial growth and activity mainly in the treatment of urinary tract infections. The sodium salt of sulfacetamide is applied topically in ophthalmic use in the treatment of eye infections. It is a white to yellowish crystalline powder; soluble in water, sparingly soluble in alcohol.

Sulfonamide is an organic sulfur compounds containing the radical -SO2NH2 (the amides of sulfonic acids). Its molecular structure is similar to p-Aminobenzoic acid (PABA) which is needed in bacteria organisms as a substrate of the enzyme dihydropteroate synthetase for the synthesis of tetrahydrofolic acid (THF). Sulfonamides, derived from chiefly sulfanilamide, are capable of interfering with the metabolic processes in bacteria that require PABA. They act as antimicrobial agents by inhibiting bacterial growth and activity and called sulfa drugs. They are used in the prevention and treatment of bacterial infections, diabetes mellitus, edema, hypertension, and gout. Sulfa drug includes;

  • Topical sulfonamides: sulfacetamide; silver sulfadiazine; mafenide; 
  • Rapidly absorbed and eliminated sulfonamides: sulfisoxazole diolamine; sulfadiazine; sulfamethoxazole;
  • Hydrophylic sulfonamides: phtalylsulfacetamide; phtalylsulfathiazole; sulfasalazine; sulfaguanidine;
  • Long lasting sulfonamides: sulfadoxine; 
  • Others: sulfamazole; sulfamazone; sulfametopirazine; sulfametoxypiridazine; sulfametrol; succinylsulfathiazole;
