PEN-VEE K vs POLYMOX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin V binds to penicillin-binding proteins (PBPs) located on the bacterial cell wall, inhibiting the final transpeptidation step of peptidoglycan synthesis, leading to cell lysis.
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 6-8 hours for mild to moderate infections; up to 2 g/day for severe infections.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours; maximum 4 g/day.

Terminal elimination half-life: 30-60 minutes in adults with normal renal function, prolonged to 3-10 hours in severe renal impairment.
Terminal elimination half-life = 1-1.5 hours in adults; prolonged in renal impairment (up to 12-20 hours in anuria)
Renal excretion of unchanged drug via glomerular filtration and tubular secretion accounts for 60-90% of elimination; biliary/fecal elimination is minimal (<10%).
Renal (70-80% unchanged via tubular secretion and glomerular filtration); biliary/fecal (small amount, <5%)
