V-CILLIN vs WYMOX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G (V-CILLIN) inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and autolysin activation, leading to cell lysis.
Amoxicillin is a semisynthetic penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
250-500 mg orally every 8 hours or 500 mg every 12 hours for mild to moderate infections.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours for 7-14 days; maximum 4 g/day.

Terminal elimination half-life ~30-60 minutes in normal renal function; prolonged in renal impairment (up to 10 hours in anuria).
0.7-1.4 hours (mean ~1 hour) in adults with normal renal function; prolonged to 2-6 hours in anuria.
Primarily renal (60-70% unchanged via tubular secretion); minor biliary/fecal elimination (<10%).
Renal: 60-70% unchanged via glomerular filtration and tubular secretion; biliary: <5%; fecal: <5%.
