There’s recently been controversy surrounding 2021 Kentucky Derby winner Medina Spirit’s credibility after traces of an illegal drug was found in the horse’s system during a postrace drug test.
The commonly used drug is called betamethasone.
Director of the Wisconsin Veterinarian Diagnostic laboratory at U-W Madison Dr. Keith Poulsen
says that drug is frequently used as an anti-inflammatory.
“When I was in practice, I would use it to inject a joint to calm down inflammation or arthritis,” said Poulsen.
Paulsen explains that the frequently used drug only recently became illegal on race day.

Medina Spirit’s postrace test detected 21 pico-grams of beta-methasone. But just how much is a pico-gram?
“Pico-grams are a billionth of a gram. It’s very minuscule amounts. We are talking about parts per billion.
