This study supports the use of a myostatin inhibitor, Fortetropin®, to prevent disuse muscle atrophy in canine patients undergoing a tibial plateau leveling osteotomy.

The recommended dosing range of Fortetropin for cats was unknown prior to this study. The purpose of this study was to evaluate the safety and tolerability of Fortetropin in 12 purpose-bred cats.

As pets age, quality of life and mobility can be impacted by pain of osteoarthritis and age-related muscle atrophy (sarcopenia).
