Sulphamethoxazole is antibacterial sulfonamide. Sulphamethoxazole is classified as an intermediate-acting sulfonamide and is longer-acting than sulfisoxazole, which allows it to be given 2-3 times daily, possibly aiding in compliance. Although it was once an extremely useful antibiotic, the development of resistance and the availability of newer agents has made sulfamethoxazole almost obsolete as a single agent. Today, clinical use of sulfamethoxazole occurs primarily in combination with trimethoprim. It was approved by the FDA in 1961 as an antibecterial agent. Sulphamethoxazole is effective against gram positive, gram negative bacteria and some protozoan.
