PENTIDS '200' vs TOTACILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and activating autolytic enzymes.
Bactericidal: inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation. Active against gram-positive bacteria and some gram-negative bacteria.
Penicillin G benzathine: 1.2 million units intramuscularly as a single dose.
250-500 mg orally every 6 hours or 1-2 g intravenously every 4-6 hours.

0.5-1 hour; prolonged in renal impairment; anuric patients up to 10 hours
Terminal elimination half-life: 1.0-1.5 hours in normal renal function. Extended to 2-6 hours in renal impairment; requires dose adjustment when CrCl <30 mL/min.
Renal: 60-90% unchanged; biliary/fecal: 10-40%
Renal: 90-95% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: <5% as unchanged drug and metabolites.
