Cefovecin differs from other cephalosporins in that it is highly protein bound and has a long duration of activity. As with all cephalosporins, the bactericidal action of cefovecin results from the inhibition of bacterial cell wall synthesis through binding to the penicillin-binding proteins (PBPs). It is indicated for the treatment of skin infections secondary superficial pyoderma, abscesses and wounds. Some gastrointestinal adverse effects like vomiting, anorexia or diarrhea were observed.
