Luitpold Animal Health, manufacturers of Adequan products, issued an update Aug. 1 on the drug’s current and future availability. The company announced in May that they expected supply shortages due to factory renovations at their Shirley, N.Y., facility, and supplies have been limited throughout the late spring and early summer.

"Luitpold has been working closely with the Food and Drug Administration to assure that Adequan is made available as soon as possible," the Aug. 1 statement read. "As a result of these efforts, we have been able to revise our target date for product availability from our original estimate of the first quarter 2014. We now anticipate release of Adequan products to the market beginning in late August 2013."

Adequan (polysulfated glycosaminoglycan) was approved by the Food and Drug Administration for equine use in 1984, and is designed to treat non-infectious degenerative and/or traumatic joint dysfunction and associated lameness of the carpal (knee) and hock joints in horses.

The statement noted that the company developed a dedicated webpage on their website where interested individuals can register to receive future information on the topic. Individuals can also contact the customer service department at 800/458-0163 for additional information
