GENERAL DESCRIPTION OF SULFONAMIDE

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; mafenide acetate;
  • 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;
