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.
Penicillin G binds to penicillin-binding proteins (PBPs) located on the bacterial cell wall, inhibiting transpeptidase activity and disrupting peptidoglycan cross-linking, leading to cell lysis.
250-500 mg orally every 6 hours; maximum 2 g/day.
400 mg orally every 6 hours.

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.
0.5-1 hour in patients with normal renal function. Prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Primarily renal excretion (tubular secretion) of unchanged drug (~90%); minor biliary/fecal elimination (<10%).
Primarily renal (tubular secretion and glomerular filtration); 60-90% of dose excreted unchanged in urine within 24 hours. Minor biliary excretion (<10%) and fecal elimination.
