🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to penicillin-binding proteins (PBPs) located inside the bacterial cell wall. This binding inhibits the transpeptidation reaction that cross-links peptidoglycan chains, which are essential for cell wall integrity. As a result, the bacterial cell wall becomes weakened, leading to cell lysis and death, especially in actively dividing bacteria. This medicine is bactericidal against susceptible organisms.

For example, for streptococcal pharyngitis, a single intramuscular dose of 1.2 million IU may be used. For serious infections, higher doses are given intravenously. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
