PENBRITIN-S vs POLYMOX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillinase-sensitive penicillin; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
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.
250-500 mg orally every 6 hours or 500 mg-1 g intramuscularly/intravenously every 4-6 hours for moderate to severe infections.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours; maximum 4 g/day.

0.5-1 hour; prolonged in renal impairment (up to 7-10 hours in anuria).
Terminal elimination half-life = 1-1.5 hours in adults; prolonged in renal impairment (up to 12-20 hours in anuria)
Renal: 75-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: ~10%.
