What is Sulfanilamide?
Sulfanilamide (also spelled sulphanilamide) is a sulfonamide antibacterial. Chemically, it is an organic compound consisting of an aniline derivitized with a sulfonamide group. Powdered sulfanilamide was used by the Allies in WWII to reduce infection rates and contributed to a dramatic reduction in mortality rates compared to previous wars. Modern antibiotics have supplanted sulfanilamide on the battlefield; however, sulfanilamide remains in use for treatment of vaginal yeast infections.
The term "sulfanilamides" is also used to describe a family of molecules containing these functional groups. Examples include:
- Furosemide, a loop diuretic
- Sulfadiazine, an antibiotic
- Sulfamethoxazole, an antibiotic
