Penicillin G potassium salt

Penicillin G is a narrow spectrum antibiotic


Penicillin G is active against gram-positive and gram-negative aerobic and anaerobic bacteria. Penicillin G inhibits cell wall synthesis by binding to penicillin binding proteins (PBPs) which inhibits peptidoglycan chain cross-lining. Penicillin G is stable against hydrolysis by β-lactamases, such as penicillinases and cephalosporinases.


Antimicrobial spectrum: This product is active against gram-positive and gram-negative bacteria.


Mode of Action: Penicillin G acts by inhibiting cell wall synthesis through binding to penicillin binding proteins (PBPs), inhibiting peptidoglycan chain cross-linking..
