PENBRITIN-S vs STAPHCILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillinase-sensitive penicillin; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
Semisynthetic penicillin; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
250-500 mg orally every 6 hours or 500 mg-1 g intramuscularly/intravenously every 4-6 hours for moderate to severe infections.
1-2 g IV every 4-6 hours.

0.5-1 hour; prolonged in renal impairment (up to 7-10 hours in anuria).
0.5-1 hour in adults with normal renal function; prolonged to 2-4 hours in renal impairment. Infants: 1-2 hours.
Renal: 75-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: ~10%.
Primarily renal (70-90% as unchanged drug via glomerular filtration and tubular secretion); minor biliary excretion (<5%) and fecal elimination (<1%).
