PENICILLIN-2 vs PENICILLIN G POTASSIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
Bactericidal: inhibits transpeptidases (penicillin-binding proteins) involved in bacterial cell wall synthesis, leading to cell lysis.
250 mg orally every 6 hours or 500 mg orally every 8 hours for mild to moderate infections; intravenous dosing: 1-2 million units every 4-6 hours.
1-4 million units IV every 4-6 hours; maximum 24 million units/day

Renal: 60-80% unchanged; biliary/fecal: minor (10-20%)
Renal (60-90% as unchanged drug via tubular secretion and glomerular filtration); biliary (minor, <10%); fecal (minimal, <5%).
