Norbrook Announces FDA Approval of Norfenicol Injectable Solution For Broad Spectrum BRD Treatment

August 13, 2015 06:24 AM

Norbrook Laboratories, Ltd. announced the FDA approval of Norfenicol® (florfenicol) Injectable Solution, a fast-acting treatment for Bovine Respiratory Disease (BRD) associated with Mannheimia haemolytica, Pasteurella multocida, and Histophilus somnus in beef and non-lactating dairy cattle. It is also indicated for the control of respiratory disease in cattle at high risk of developing BRD associated with M. haemolytica, P. multocida, and H. somni, as well as the treatment of bovine interdigital phlegmon (foot rot, acute interdigital necrobacillosis, infectious pododermatitis) associated with Fusobacterium necrophorum and Bacteroides melaninogenicus.

According to Chip Whitlow, Marketing Manager for Norbrook, Inc., Norfenicol has the same active ingredient as NuflorÒ (florfenicol) and will include two additional, innovative product features. “The first is Norfenicol will have a shorter withdrawal period than Nuflor when administered Sub-Q (33 days vs. 38 days). In addition, Norfenicol will be the only injectable antibiotic for cattle sold in the US in an unbreakable plastic bottle. This eliminates the expense of product breakage when mishandled,” announces Whitlow.

“Florfenicol, the active ingredient in Norfenicol, is a proven compound in the treatment of BRD,” states Dr. Eric Moore, Director of Technical Services, Norbrook, Inc.  Dr. Moore adds, “With the price of cattle, and both the immediate and hidden costs of BRD, an effective antibiotic like Norfenicol is essential in giving the cattle producer piece of mind when battling BRD.”

New Norfenicol will soon be available from veterinarians in unbreakable plastic 100 mL, 250 mL and 500 mL bottles to fit any size operation. For more information about new Norfenicol Injectable Solution, contact your veterinarian or local animal health products supplier or Norbrook, Inc. at
