PENICILLIN G POTASSIUM vs POLYMOX
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.
Amoxicillin is a bactericidal antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) and inhibiting transpeptidase activity, leading to cell lysis.
1-4 million units IV every 4-6 hours; maximum 24 million units/day
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours; maximum 4 g/day.

0.5-1 hour in normal renal function; prolonged to 3-10 hours in anuria/end-stage renal disease.
Terminal elimination half-life = 1-1.5 hours in adults; prolonged in renal impairment (up to 12-20 hours in anuria)
Renal (60-90% as unchanged drug via tubular secretion and glomerular filtration); biliary (minor, <10%); fecal (minimal, <5%).
