🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) located inside the bacterial cell wall. This binding prevents the cross-linking of peptidoglycan chains, which is essential for cell wall strength and rigidity. As a result, the bacterial cell wall becomes weak and the cell undergoes lysis and death. This medicine is bactericidal and is active against a broad spectrum of Gram-negative and Gram-positive bacteria.
