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. It is marketed as Histostat by Zoetis, a publicly traded subsidiary of Pfizer.
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. 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. 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. When the withdrawals occur, nitarsone will be the only arsenical approved for use in food animals in the U.S.
