STAPHCILLIN vs V-CILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Semisynthetic penicillin; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
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.
1-2 g IV every 4-6 hours.
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 2-4 hours in renal impairment. Infants: 1-2 hours.
Terminal elimination half-life ~30-60 minutes in normal renal function; prolonged in renal impairment (up to 10 hours in anuria).
Primarily renal (70-90% as unchanged drug via glomerular filtration and tubular secretion); minor biliary excretion (<5%) and fecal elimination (<1%).
Primarily renal (60-70% unchanged via tubular secretion); minor biliary/fecal elimination (<10%).
