PENAPAR-VK vs POLYMOX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin V is a bactericidal antibiotic that inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
Amoxicillin is a bactericidal antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) and inhibiting transpeptidase activity, leading to cell lysis.
250-500 mg orally every 6 hours; maximum 2 g/day.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours; maximum 4 g/day.

Terminal elimination half-life: 0.5–1 hour in normal renal function; prolonged to 7–10 hours in severe renal impairment (anuria). Requires dose adjustment in renal failure.
Terminal elimination half-life = 1-1.5 hours in adults; prolonged in renal impairment (up to 12-20 hours in anuria)
Primarily renal excretion (tubular secretion) of unchanged drug (~90%); minor biliary/fecal elimination (<10%).
Renal (70-80% unchanged via tubular secretion and glomerular filtration); biliary/fecal (small amount, <5%)
