Ceftiofur is an antibiotic of the cephalosporin type (third generation), licensed for use in veterinary medicine only. It was first described in 1987. It is marketed by pharmaceutical company Zoetis as Excenel, Naxcel, and Excede and is also the active ingredient in that company's Spectramast LC (lactating cow formulation) and Spectramast DC (dry cow formulation) product. Ceftiofur has worldwide approvals for respiratory disease in swine, ruminants (cattle, sheep and goats) and horses and has also been approved for foot rot and metritis infections in cattle. Ceftiofur has also been approved in various countries for early mortality infections in day-old chicks and turkey poults. Ceftiofur (NAXCEL) is indicated for treatment of bovine respiratory disease (shipping fever, pneumonia) associated with Mannheimia haemolytica, Pasteurella multocida, and Histophilus somni. NAXCEL is also indicated for treatment of acute bovine interdigital necrobacillosis (foot rot, pododermatitis) associated with Fusobacterium necrophorum and Bacteroides melaninogenicus.

Sample Use Guides

In Vivo Use Guide

Administer to cattle by intramuscular or subcutaneous injection at the dosage of 0.5 to 1.0 mg ceftiofur per pound (1.1 to 2.2 mg/kg) of body weight (1-2 mL reconstituted sterile solution per 100 lbs body weight). Treatment should be repeated at 24-hour intervals for a total of three consecutive days. Additional treatments may be given on days four and five for animals which do not show a satisfactory response (not recovered) after the initial three treatments. Selection of dosage (0.5 to 1.0 mg/lb) should be based on the practitioner’s judgement of severity of disease.

Route of Administration: Intramuscular

In Vitro Use Guide

Ceftiofur had the highest in vitro activity with an MIC(50) of 2.2 ug/ml against isolates of A. pleuropneumoniae collected from pigs with hemorrhagic pneumonia
