Six R, Cleaver DM, Lindeman CJ, et al. Effectiveness and safety of cefovecin sodium, an extended-spectrum injectable cephalosporin, in the treatment of cats with abscesses and infected wounds. J Am Vet Med Assoc. Jan 1 2009;234(1):81-87.
Abscesses and infected bite or scratch wounds are very common problems in feline medicine. The most common pathogen involved is Pasteurella multocida
. Treatment of infected wounds is accomplished by drainage and debridement, and antibiotic therapy. Antibiotics typically recommended for first line treatment include penicillins, cephalosporins, and clindamycin. These drugs require once or twice daily dosing, and treatment must be continued for 7 to 14 days. Cefovecin (Convenia, Pfizer Animal Health) is a new extended-spectrum bactericidal cephalosporin. The manufacturer recommends a one-time subcutaneous injection at a dose of 8 mg/kg. Therapeutic concentrations of the drug against P. multocida
are maintained for approximately 7 days. This multicenter, randomized, double-blinded, controlled clinical trial was designed to evaluate the effectiveness and safety of cefovecin in the treatment of cats with abscesses and infected wounds. Cats were randomly allocated to one of two groups. One group received a single dose of cefovecin followed by placebo drops orally once daily for 14 days. The second group received one subcutaneous placebo injection followed by cefadroxil once daily for 14 days. The effectiveness of cefovecin was similar to that of cefadroxil. At day 28, 97% of cefovecin-treated cats and 91% of cefadroxil-treated cats were considered treatment successes. There were no serious adverse effects reports.
