How Cefdinir works
Cefdinir is a third-generation cephalosporin antibiotic.
It works by inhibiting the synthesis of the bacterial cell wall. This is achieved by the medicine binding to and inactivating specific enzymes called penicillin-binding proteins. These proteins are crucial for creating the peptidoglycan layer of the bacterial cell wall. By interrupting this process, Cefdinir causes the bacterial cells to burst open, leading to their eventual death. This mechanism of action makes Cefdinir effective against a wide range of bacteria, helping to manage various bacterial infections.
