PENTIDS '250' vs STAPHCILLIN
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 cell wall synthesis, leading to bacterial lysis.
Semisynthetic penicillin; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
250 mg orally every 8 hours.
1-2 g IV every 4-6 hours.

0.5-1 hour (prolonged in renal impairment; requires dose adjustment when CrCl <30 mL/min)
0.5-1 hour in adults with normal renal function; prolonged to 2-4 hours in renal impairment. Infants: 1-2 hours.
Primarily renal (60-90% as unchanged drug via glomerular filtration and tubular secretion); minor biliary/fecal (10-30%)
Primarily renal (70-90% as unchanged drug via glomerular filtration and tubular secretion); minor biliary excretion (<5%) and fecal elimination (<1%).
