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 transpeptidase activity and disrupting peptidoglycan synthesis, leading to cell lysis.
Penicillin V exerts bactericidal activity by inhibiting bacterial cell wall synthesis through binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
250-500 mg orally every 6 hours for mild to moderate infections; 500 mg orally every 6 hours for severe infections; up to 500 mg orally every 4 hours for severe infections.

0.5-1 hour in patients with normal renal function; prolonged to 7-10 hours with creatinine clearance <10 mL/min.
0.5–1 hour (normal renal function); prolonged to 2–6 hours in renal impairment.
Renal excretion accounts for 20-40% of the dose as unchanged drug via tubular secretion and glomerular filtration; biliary/fecal excretion is minimal (<10%).
Renal: 60-90% unchanged via tubular secretion and glomerular filtration; minor biliary/fecal: <10%.
