DURACILLIN A.S. vs V-CILLIN
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 G (V-CILLIN) inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and autolysin activation, leading to cell lysis.
600,000 units intramuscularly once daily; or 1.2 million units intramuscularly every 12 hours for severe infections.
250-500 mg orally every 8 hours or 500 mg every 12 hours for mild to moderate infections.

0.5-1 hour in adults with normal renal function; prolonged to 7-10 hours in end-stage renal disease
Terminal elimination half-life ~30-60 minutes in normal renal function; prolonged in renal impairment (up to 10 hours in anuria).
Primarily renal (60-90% unchanged via tubular secretion and glomerular filtration); minor biliary/fecal elimination (<10%)
