Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G procaine is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
Penicillin V is a bactericidal antibiotic that inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
600,000 units intramuscularly once daily; or 1.2 million units intramuscularly every 12 hours for severe infections.
250-500 mg orally every 6 hours; maximum 2 g/day.

0.5-1 hour in adults with normal renal function; prolonged to 7-10 hours in end-stage renal disease
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.
Primarily renal (60-90% unchanged via tubular secretion and glomerular filtration); minor biliary/fecal elimination (<10%)
Primarily renal excretion (tubular secretion) of unchanged drug (~90%); minor biliary/fecal elimination (<10%).
