Pharmacology/Spectrum of Activity
Ceftiofur inhibits cell wall synthesis (at stage three) of susceptible multiplying bacteria. Ceftiofur exhibits a spectrum of activity similar to that of cefotaxime. It has a broad range of in vitro activity against a variety of pathogens, including many species of Pasturella, Streptococcus, Staphylococcus, Salmonella, and E.coli.
Ceftiofur sodium/HCl is indicated for treatment of bovine respiratory disease (shipping fever, pneumonia) associated with Pasturella hemolytica, Pasturella multocida and Haemophilus somnus in lactating or non-lactating cattle and ceftiofur sodium is indicated in horses for respiratory disease associated with Strep zooepidimicus:. Ceftiofur HCl is also approved for foot rot in cattle.
Ceftiofur could potentially be of usefulness in small animal infections as well, but little published data is available to recommend its use.
In cattle, ceftiofur sodium and HCl have practically equivalent pharmacokinetic parameters. Peak levels of ceftiofur are slightly higher after IM injection of Naxcel®, but areas under the curve are practically equal as well as elimination half-lives (approx. 9-12 hours).
For labeled indications:
a) 1.1 - 2.2 mg/kg IM once daily for 3 treatments; may give additional doses on 4th and 5th day if response is not satisfactory.
b) 1.1 - 2.2 mg/kg IM or SQ once daily for 3 treatments; may give additional doses on 4th and 5th day if response is not satisfactory
For respiratory disease associated with Strep zooepidimicus::
2.2 - 4.4 mg/kg (2 - 4 ml reconstituted sterile solution per 100 lb. of body weight) with a maximum of 10 ml administered per injection site. Repeat treatment at 24 hour intervals, continued for 48 hours after symptoms have disappeared. Do not exceed 10 days of treatment.
