POLYMOX vs SPECTROBID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Spectrobird (bacampicillin) is a prodrug of ampicillin, a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours; maximum 4 g/day.
400 mg orally twice daily or 200 mg orally four times daily for 10-14 days. For acute exacerbations of chronic bronchitis: 400 mg orally twice daily for 10 days.

Terminal elimination half-life = 1-1.5 hours in adults; prolonged in renal impairment (up to 12-20 hours in anuria)
Terminal elimination half-life: 1.5-2 hours in normal renal function; prolonged to 6-10 hours in severe renal impairment (CrCl <10 mL/min).
Renal (70-80% unchanged via tubular secretion and glomerular filtration); biliary/fecal (small amount, <5%)
Renal: ~75-85% unchanged drug; fecal/biliary: ~15-25% as metabolites and unchanged drug.
