Nitarsone is an organoarsenic compound that is used in poultry production as a feed additive to increase weight gain, improve feed efficiency, and prevent blackhead disease.[1] It is marketed as Histostat by Zoetis, a publicly traded subsidiary of Pfizer.[2]
Nitarsone is one of four arsenical animal drugs approved by the U.S. Food and Drug Administration for use in poultry, along with roxarsone, arsanilic acid, and carbarsone.[3] Following the 2011 suspension of roxarsone sales in the United States, however, it is believed to be the only arsenical animal drug currently marketed in the U.S.[3][4] In September 2013, the FDA announced that Zoetis and Fleming Laboratories would voluntarily withdraw current roxarsone, arsanilic acid, and carbarsone approvals, leaving only nitarsone approvals in place.[5] When the withdrawals occur, nitarsone will be the only arsenical approved for use in food animals in the U.S.
