PENICILLIN G POTASSIUM vs TOTACILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal: inhibits transpeptidases (penicillin-binding proteins) involved in bacterial cell wall synthesis, leading to cell lysis.
Bactericidal: inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation. Active against gram-positive bacteria and some gram-negative bacteria.
1-4 million units IV every 4-6 hours; maximum 24 million units/day
250-500 mg orally every 6 hours or 1-2 g intravenously every 4-6 hours.

0.5-1 hour in normal renal function; prolonged to 3-10 hours in anuria/end-stage renal disease.
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% as unchanged drug via tubular secretion and glomerular filtration); biliary (minor, <10%); fecal (minimal, <5%).
Renal: 90-95% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: <5% as unchanged drug and metabolites.
