Medina Spirit was treated with Otomax, which contains betamethasone, for this skin rash.
A split of the post-Kentucky Derby blood sample pulled from winner Medina Spirit confirmed the presence of the regulated corticosteroid betamethasone, the attorney for the colt’s trainer, Bob Baffert, confirmed Wednesday.
The split sample tested positive for 25 picograms per milliliter of blood serum, according to the attorney, Craig Robertson. That concentration is consistent with the result of the initial test, which tested at 22 picograms, Robertson had said earlier.
