OSPHOS is an injectable bisphosphonate solution for the control of clinical signs associated with navicular syndrome in horses four years and older. The injection inhibits bone resorption by binding to calcium phosphate crystals (inhibiting their formation and dissolution), and by exerting direct cellular effects on osteoclasts.
Each vial contains 15 mL (900 mg) of clodronate disodium (60 mg/mL) and is ready-to-use; does not require reconstitution or dilution.
