Understanding Antibiotic Classifications
To apprehend why Keflex is not a sulfa drug, it is significant to realise how antibiotics are categorize. Antibiotics are mostly aggroup based on their chemical construction and the mechanism through which they contend bacterium.

What are Sulfa Drugs?
Sulfa drugs, or sulfonamides, are a group of synthetic antimicrobial agents that contain a sulfonamide chemical group.

What is Keflex (Cephalexin)?
Keflex is classify as a first-generation mefoxin. Cephalosporins are beta-lactam antibiotics, meaning they percentage a chemical structure alike to penicillin. They act by interfering with the development of the bacterial cell wall, which finally leads to the wipeout of the bacterium. Because their chemic make-up is discrete from sulfonamide, they function within a completely different pharmacological family.
Comparing Antibiotic Families
