PENTIDS '400' vs V-CILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
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.
400 mg orally every 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 patients with normal renal function. Prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Terminal elimination half-life ~30-60 minutes in normal renal function; prolonged in renal impairment (up to 10 hours in anuria).
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.
Primarily renal (60-70% unchanged via tubular secretion); minor biliary/fecal elimination (<10%).
