sulfanilamide

Sulfanilamide is an antibiotic medication that was one of the first effective drugs used to treat bacterial infections. It works by blocking the bacteria’s ability to produce folic acid, which is essential for their growth and multiplication. Without folic acid, bacteria cannot survive or reproduce, helping the body fight off infections. Although its use has declined with the availability of newer antibiotics, sulfanilamide laid the foundation for modern antimicrobial therapy and played a key role in controlling bacterial diseases.
