PENICILLIN G POTASSIUM IN PLASTIC CONTAINER vs PENTIDS '250'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation 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 IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).
250 mg orally every 8 hours.

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