February 17, 2014: Today Ark Sciences, LLC, officially launched Zeuterin™ for commercial use in the United States. (The counterpart EsterilSol™, which is the same product and non-U.S. brand name, was already approved in several other countries).
Zeuterin/EsterilSol was developed to chemically sterilize male dogs through a process called "zinc neutering" with the chemical compound zinc gluconate neutralized by arginine. The formulation was initially introduced in the U.S. under the name Neutersol and is the only permanent non-surgical sterilant to receive regulatory approval from the U.S. Food and Drug Administration (FDA). Zeuterin provides permanent sterility in a single treatment and makes it possible to sterilize male dogs who might otherwise contribute to homeless pet populations. For many animal shelters and sterilization clinics, this approach will require less time, money, and infrastructure than surgical castration, helping these organizations reach further with limited resources.
Ark Sciences reports plans to seek regulatory approval in additional countries moving forward. Currently, this product may be able to be used with special permission on a limited basis in some countries in which it does not have regulatory approval.
ACC&D’s goal is to help organizations explore how EsterilSol/Zeuterin may help them sterilize more dogs and/or conserve their limited resources, and, where it is a good fit, to help organizations utilize it effectively.
