Answer

Sulfonamides

Sulfamethoxazole and trimethoprim (Bactrim, Bactrim DS, Cotrim, Cotrim DS, Septra, Septra DS)

Sulfamethoxazole and trimethoprim is a sulfonamide derivative antibiotic. This agent inhibits bacterial synthesis of dihydrofolic acid by competing with paraaminobenzoic acid, thereby inhibiting folic acid synthesis and resulting in inhibition of bacterial growth. The antibacterial activity of TMP-SMZ includes common urinary tract pathogens, except P aeruginosa.
