Chemical Properties

white crystalline solid


Cefaclor belongs to the family of antibiotics known as the cephalosporins (cefalosporins). The cephalosporins are broad-spectrum antibiotics that are used for the treatment of septicaemia, pneumonia, meningitis, biliary-tract infections, peritonitis, and


radioopaque agent


ChEBI: A cephalosporin bearing chloro and (R)-2-amino-2-phenylacetamido groups at positions 3 and 7, respectively, of the cephem skeleton.

brand name

Ceclor (Lilly); Raniclor (Ranbaxy).

Antimicrobial activity

It is less resistant than other group 2 cephalosporins to staphylococcal β-lactamase. It is active against N. gonorrhoeae and H. influenzae and against most enterobacteria, but it is susceptible to common enterobacterial β-lactamases. Pr. vulgaris and Providencia, Acinetobacter and Serratia spp. are resistant. B. fragilis and clostridia are resistant but other anaerobes are commonly susceptible.


Oral absorption: c. 90%
Cmax 250 mg oral: c. 6–7 mg/L after 50 min
Plasma half-life: 0.5–1 h
Volume of distribution: 0.37 L
Plasma protein binding: 25%
Food intake increases the time taken to reach peak plasma levels and reduces the peak by 25–50%. The actual amount absorbed is unaffected. In children receiving 15 mg/kg per day (maximum daily dose 1 g) the mean peak serum level was 16.8 mg/L at 0.5–1 h. There is no accumulation of the drug during repeated administration.
In patients receiving 500 mg every 8 h for 10 days, concentrations were 0–1.7 (mean 0.5) mg/L in mucoid sputum and 0–2.8 (mean 1.0) mg/L in purulent sputum. In children with chronic serous otitis media receiving 15 mg/kg per day, the mean peak concentration in middle ear secretion was 3.8 mg/L within 30 min of the dose when the mean simultaneous serum concentration was 12.8 mg/L.
Metabolism and excretion No metabolites have been identified, but the drug probably chemically degrades in serum. About half of the dose is recovered from the urine in the first 6 h and 70% in 24 h. Probenecid prolongs the plasma levels but in renal insufficiency the plasma half-life is only moderately increased. In patients with creatinine clearance values of 5–15 mL/min the mean plasma elimination half-life rose to 2.3 h and the 24 h urinary excretion fell to less than 10%. In patients requiring intermittent hemodialysis and receiving 500 mg every 8 h for 10 days, the half-life rose to 2.9 h. Dialysis removed 34% of the dose

Clinical Use

Uses are similar to those of other group 2 cephalosporins. It is among the few suitable for use in respiratory infections because of its activity against H. influenzae.

Side effects

Apart from mild gastrointestinal disturbance, the drug is well tolerated. Transiently increased transaminase levels and symptomatic vaginal candidosis have been noted. Clusters of a serum sickness-like illness have been described in children.
