PENICILLIN G POTASSIUM vs PENTIDS '250'
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 binds to penicillin-binding proteins (PBPs) located on the bacterial cell wall, inhibiting transpeptidase activity and cell wall synthesis, leading to bacterial lysis.
1-4 million units IV every 4-6 hours; maximum 24 million units/day
250 mg orally every 8 hours.

0.5-1 hour (prolonged in renal impairment; requires dose adjustment when CrCl <30 mL/min)
Renal (60-90% as unchanged drug via tubular secretion and glomerular filtration); biliary (minor, <10%); fecal (minimal, <5%).
