PENTIDS '400' 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 disrupting peptidoglycan cross-linking, leading to cell lysis.
Semisynthetic penicillin; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
400 mg orally every 6 hours.
1-2 g IV every 4-6 hours.

0.5-1 hour in patients with normal renal function. Prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
0.5-1 hour in adults with normal renal function; prolonged to 2-4 hours in renal impairment. Infants: 1-2 hours.
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 (70-90% as unchanged drug via glomerular filtration and tubular secretion); minor biliary excretion (<5%) and fecal elimination (<1%).
