PENICILLIN G SODIUM vs PENTIDS '800'
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 is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), transpeptidases that catalyze the final transpeptidation step of peptidoglycan cross-linking, leading to cell 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).
800 mg orally every 6 to 8 hours; maximum 4 g per day.

30-60 minutes in normal renal function; prolonged to 7-10 hours in anuria.
0.5-1 hour; prolonged to 2-5 hours in renal impairment.
Primarily renal (60-90% unchanged) via glomerular filtration and tubular secretion; minor biliary/fecal (<10%).
Renal: ~60-85% unchanged via glomerular filtration and tubular secretion; Biliary: ~10%; Fecal: <5%.
