PENICILLIN G SODIUM vs TRIMOX
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.
Amoxicillin is a semisynthetic penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis and death.
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).
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours depending on infection severity.

30-60 minutes in normal renal function; prolonged to 7-10 hours in anuria.
Terminal elimination half-life: 1-1.5 hours (normal renal function); in renal impairment (CrCl <10 mL/min), extends to 6-20 hours, requiring dose adjustment.
Primarily renal (60-90% unchanged) via glomerular filtration and tubular secretion; minor biliary/fecal (<10%).
Renal: 50-85% unchanged via glomerular filtration and tubular secretion; biliary/fecal: minimal, <5%.
