A clear, colourless, odourless solution containing 10 mg/ml Butorphanol as the tartrate in amber 20 mL vials.
Butorphanol is a synthetic centrally acting analgesic and a potent antitussive.
Clinical studies in the horse have shown that butorphanol tartrate alleviates abdominal pain associated with colic and postpartum pain. Used in combination with tranquillisers or sedatives butorphanol is effective for chemical restraint in standing surgical procedures.
