🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins, specifically transpeptidases, which are enzymes involved in cross-linking peptidoglycan chains in the bacterial cell wall. This inhibition weakens the cell wall, leading to bacterial cell lysis and death. It is bactericidal against susceptible organisms.
