PENICILLIN G POTASSIUM vs PENTIDS '200'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal: inhibits transpeptidases (penicillin-binding proteins) involved in bacterial cell wall synthesis, leading to cell lysis.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and activating autolytic enzymes.
1-4 million units IV every 4-6 hours; maximum 24 million units/day
Penicillin G benzathine: 1.2 million units intramuscularly as a single dose.
