C
Feedback:
Sulfonamides (commonly called sulfa drugs) are used as antimicrobial agents, chiefly because of their low cost and effectiveness in treating common bacterial infections. They are bacteriostatic agents, requiring normal body processes to eradicate infection. Although the sulfa drugs are very effective, newer and more effective antibiotics with fewer side effects and faster rates of action are replacing them.
