PENICILLIN G SODIUM vs PENTIDS '250'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
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.
2-4 million units intravenously every 4 hours for moderate to severe infections; up to 24 million units/day for severe infections (e.g., meningitis, endocarditis).
250 mg orally every 8 hours.

30-60 minutes in normal renal function; prolonged to 7-10 hours in anuria.
0.5-1 hour (prolonged in renal impairment; requires dose adjustment when CrCl <30 mL/min)
Primarily renal (60-90% unchanged) via glomerular filtration and tubular secretion; minor biliary/fecal (<10%).
