  • Septra.
  • Septra DS.

What is the difference between trimethoprim sulfamethoxazole and sulfadiazine?

The primary difference between sulfamethoxazole and sulfadiazine is that sulfamethoxazole is metabolized more extensively. Sulfadiazine may attain higher active urine concentrations in some patients.

What is the use of Sulphadimidine?

Sulfa drugs kill bacteria and fungi by interfering with cell metabolism.

Can trimethoprim treat skin infections?
