CECLOR vs SUPRAX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefaclor, a second-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It exhibits bactericidal activity against susceptible organisms.
Cefixime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan cross-linking. It has broad-spectrum activity against gram-positive and gram-negative bacteria.
250 mg orally every 8 hours; for severe infections, 500 mg orally every 8 hours.
400 mg orally once daily or 200 mg orally every 12 hours.

Terminal elimination half-life: 0.6-0.9 hours in adults with normal renal function. Prolonged to 2-3 hours in end-stage renal disease. Half-life does not increase significantly with hepatic impairment.
Terminal elimination half-life: 3-4 hours in normal renal function; prolonged to 11-15 hours in severe renal impairment (CrCl <20 mL/min).
Primarily renal: 80-90% of unchanged drug excreted by glomerular filtration and tubular secretion within 8 hours. Biliary excretion accounts for <5%; fecal elimination negligible.
Renal: 50-55% unchanged in urine; biliary/fecal: 10-20% (biliary excretion); remainder metabolized or excreted via feces.
