A Florida pharmacy, which incorrectly mixed medicine, which killed 21 polo horses on a Venezuelan team a year back, is proposed to be banned by the U. S. authorities.

The practice of improperly mixing active pharmaceutical ingredients into animal drugs is considered illegal by the Justice Department and Food and Drug Administration.

The firm also admitted last year that the mixture it had made has killed the horses on the order of a veterinarian. According to the state veterinarian, the horses died after receiving a fatal dose of the mineral selenium in a vitamin supplement. They belonged to the Lechuza Caracas polo team.

FDA asked a court to issue a permanent injunction against the Florida firm and the CEO to halt the practice of compounding, i. e., the practice of using active ingredients in mixing medicines for animals.

Bernadette Dunham, Director of the FDA's Center for Veterinary Medicine said, “But when compounders like Franck's circumvent, and thus undermine, the statutory drug approval process by manufacturing drugs under the guise of pharmacy compounding, we are concerned that poorly compounded drugs can jeopardize the health of animals”.
