Evaluation of an anti-infective combination. Trimethoprim-sulfamethoxazole (Bactrim, Septra)
Abstract:
Trimethoprim and sulfamethoxazole, combined in a synthetic anti-infective preparation, act synergistically to inhibit the growth of certain microorganisms. This combination is effective orally in acute and chronic urinary tract infections. It also has been used successfully to treat other infectious conditions, including bacterial upper respiratory tract infections, ear infections, skin and soft-tissue infections, septicemias, acute and subacute bacterial endocarditis, enteric fever, brucellosis, prostatitis, and gonorrhea. It is well tolerated by most patients.
