PENBRITIN vs WYMOX
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 preventing peptidoglycan cross-linking, 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 6 hours; 500 mg to 2 g intramuscularly or intravenously every 4-6 hours.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours for 7-14 days; maximum 4 g/day.

0.5-1 hour in normal renal function; extended to 2-6 hours in renal impairment. Hemodialysis shortens half-life.
0.7-1.4 hours (mean ~1 hour) in adults with normal renal function; prolonged to 2-6 hours in anuria.
Renal: ~75-90% unchanged via glomerular filtration and tubular secretion. Biliary: ~10% in feces. Minor hepatic metabolism to penicilloic acid.
Renal: 60-70% unchanged via glomerular filtration and tubular secretion; biliary: <5%; fecal: <5%.
