FDA approves combination feeding of Pennchlor, Rumensin to beef cattle

The Food and Drug Administration on July 28 approved feeding Pennchlor, which contains chlortetracycline, and Rumensin, which contains monensin, in combination under a veterinary feed directive to beef calves 2 months of age and older and to growing beef steers and heifers fed in confinement for slaughter. The drug sponsor is Pharmgate Inc.

“We are very excited about the opportunity and flexibility this new combination claim provides feedlot operators and cattle producers,” said Ed Seed, vice president of global sales and marketing at Pharmgate Animal Health. “We’ve been working over the past month to make the updated labeling and Veterinary Feed Directive forms available to the cattle feed and veterinary industry and are now working collaboratively to roll this out more broadly.”

Pennchlor and Rumensin are Type A medicated articles to be used in the manufacture of Type B and Type C medicated feeds. See the FDA page regarding recent animal drug approvals for additional indications for this combination and other new approvals.
