indication

For the treatment of the following infections (respiratory, skin, soft tissue, UTI, ENT) caused by; S. pneumoniae, H. influenzae, staphylococci, S. pyogenes (group A beta-hemolytic streptococci), E. coli, P. mirabilis, Klebsiella sp, coagulase-negative staph

pharmacology

Cefprozil, a semisynthetic, second-generation cephalosporin, is used to treat otitis media, soft-tissue infections, and respiratory tract infections.

mechanism of action

Cefprozil, like the penicillins, is a beta-lactam antibiotic. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that cefprozil interferes with an autolysin inhibitor.

toxicity

Single 5000 mg/kg oral doses of cefprozil caused no mortality or signs of toxicity in adult, weaning or neonatal rats, or adult mice. A single oral dose of 3000 mg/kg caused diarrhea and loss of appetite in cynomolgus monkeys, but no mortality.

biotransformation

Cefprozil is eliminated primarily by the kidneys

absorption

Oral bioavailability is approximately 95%.

half life

1.3 hours
