AUGMENTIN '125' vs GEOPEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Carbenicillin is a bactericidal penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has activity against Gram-negative and some Gram-positive bacteria.
One AUGMENTIN '125' tablet (amoxicillin 125 mg, clavulanate 31.25 mg) orally every 8 hours for mild to moderate infections.
2 g intravenously every 6 hours for susceptible infections.

Amoxicillin: 1.0-1.3 hours (prolonged in renal impairment; up to 7-20 hours in anuria). Clavulanate: 0.9-1.2 hours (increased in renal impairment).
Terminal half-life 4-6 hours in normal renal function; prolonged to 10-20 hours in moderate renal impairment (CrCl 10-50 mL/min) and up to 30-50 hours in severe impairment (CrCl <10 mL/min).
Amoxicillin: ~50-70% excreted unchanged in urine via glomerular filtration and tubular secretion; clavulanate: ~30-50% excreted unchanged in urine. Small amounts eliminated in bile and feces.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: <2%.
