Cefaclor is a semisynthetic second generation cephalosporin antibiotic. It is chemically designed as 3-Chloro-7-D (2-phenylglycinamido)-3-cephem-4 carboxylic acid monohydrate. Its empirical formula is C15H14ClN3O4S·H20 and its molecular formula is 385.8.
Pharmacology: Pharmacodynamics: Mechanism of Action: Cefaclor is a bactericidal cephalosporin and like other cephalosporins is an inhibitor of bacterial cell wall synthesis. It acylates membrane-bound transpeptidase enzymes thus preventing the cross-linking of peptidoglycan necessary for bacterial cell wall strength and rigidity.
Pharmacokinetics: Cefaclor is well absorbed after oral administration. The presence of food may delay the absorption of cefaclor, but the total amount absorbed remains unchanged. Serum levels of 6 mg/1 mcg and 13 mg/1 mcg are obtained after 250 mg and 500 mg of cefaclor respectively. Peak serum concentrations are obtained in 0.5 hour to 1 hour. About 25% is protein bound. Cefaclor is widely distributed in the body. It is rapidly excreted by the kidneys, up to 85% of a dose appears unchanged in the urine within two hours. The plasma elimination half life cefaclor is about 30 minutes to 1 hour.
Cefaclor is indicated in the treatment of respiratory tract infection, acute bronchitis and acute exacerbation of chronic bronchitis, pneumonia, otitis media, pharyngitis, tonsillitis, sinusitis, urinary tract infections and skin and soft tissue infections.
