CECLOR CD vs CEFTRIAXONE SODIUM
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), thereby disrupting peptidoglycan cross-linking.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
250-500 mg orally every 8 hours; extended-release form (CECLOR CD) 375-750 mg orally every 12 hours.
1-2 g IV/IM every 12-24 hours; maximum 4 g/day.

Terminal elimination half-life: ~0.6-0.9 hours (prolonged in renal impairment)
Terminal elimination half-life is 5.8-8.7 hours in adults with normal renal and hepatic function. In neonates, half-life is prolonged (up to 16 hours). In patients with renal impairment, half-life increases to 12-18 hours; in hepatic impairment, it may be 15-20 hours. Dose adjustment is not typically required unless both renal and hepatic impairment are present.
Renal: ~80% unchanged; biliary/fecal: ~20%
Ceftriaxone is eliminated 33-67% unchanged in urine via glomerular filtration and tubular secretion, and the remainder is excreted in feces (primarily as microbiologically inactive metabolites) via biliary secretion. Biliary excretion accounts for approximately 35-45% of total clearance.
