CIDRs approved for sheep

The Food and Drug Administration (FDA) recently announced the approval of the EAZI-Breed CIDR Sheep Insert (progesterone solid matrix) for induction of estrus in ewes (sheep) during seasonal anestrus. This progesterone Controlled Intravaginal Drug Release (CIDR) is a steroid hormone that allows out-of-season breeding in sheep.

The data to support this approval were gathered in collaboration with the National Research Support Project–7 (NRSP-7), a USDA program intended to support the approval of new animal drugs for minor species of agricultural importance.

“Members of the U.S. sheep industry have long cited this type of product as their top priority need,” said, Dr. Meg Oeller, Director, Center for Veterinary Medicine, Office of Minor Use and Minor Species Animal Drug Development.

EAZI-Breed CIDR Sheep Insert is manufactured by Pharmacia and Upjohn, a division of Pfizer, Inc., New York, NY.
