Mode of Action
Benzylpenicillin has a bactericidal action against gram-positive bacteria, gram-negative cocci, some other gram-negative bacteria, spirochetes and actinomycetes. It inhibits final cross-linking stage of peptidoglycan production through binding and inactivation of transpeptidases on the inner surface of the bacterial cell membrane thus inhibiting bacterial cell wall synthesis. It is inhibited by penicillinase and other beta-lactamases.
