Active Ingredient Description
Sulfadiazine

Sulfadiazine is an antibiotic that belongs to the class of drugs known as sulphonamides. Sulfadiazine is a structural analogue and competitive antagonist of p-aminobenzoic acid preventing bacterial utilisation of PABA in the synthesis of folic acid.

Sulfadoxine
Sulfafurazole
Sulfamethoxazole

Sulfamethoxazole competitively inhibits the utilisation of para-aminobenzoic acid in the synthesis of dihydrofolate by the bacterial cell resulting in bacteriostasis.

Sulfametrole
Sulfapyridine
Sulfathiazole
Trimethoprim

Trimethoprim is a dihydrofolate reductase inhibitor, inhibiting the conversion of bacterial dihydrofolic acid to tetrahydrofolic acid, required for the synthesis of some amino acids. Its effects are considerably greater on the cells of micro-organisms than on the mammalian cells.
