PENICILLIN G POTASSIUM IN PLASTIC CONTAINER vs UTIMOX
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), inhibiting transpeptidation and activating autolytic enzymes.
Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation. Clavulanate is a beta-lactamase inhibitor that irreversibly binds to and inactivates beta-lactamases, preventing hydrolysis of amoxicillin.
2-4 million units IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).
For UTIMOX (amoxicillin/clavulanate), typical adult dose is 875 mg/125 mg orally every 12 hours or 500 mg/125 mg orally every 8 hours, depending on infection severity.

0.5–1 hour (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
Terminal elimination half-life: 1.0-1.5 hours in adults with normal renal function; prolonged to 3-5 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 8-12 hours in severe impairment (CrCl <30 mL/min).
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
Primarily renal (85-90% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for less than 10%.
