Butorphic® (Butorphanol Tartrate) Injection is a synthetic centrally acting, narcotic agonist-antagonist analgesic with potent antitussive activity.

10 mg/mL Sterile Injectable Solution

INDICATIONS: Butorphic is indicated for the relief of pain associated with colic and postpartum pain in adult horses and yearlings. Clinical studies in the horse have shown that butorphanol tartrate alleviates abdominal pain, associated with torsion, impaction, intussusception, spasmodic and tympanic colic, and postpartum pain. Butorphic is a potent analgesic, and should be used with caution with other sedative or analgesic drugs as these are likely to produce additive effects.

FDA Approved under ANADA #200-332; this product is considered a generic equivalent
to the reference product, Tobugesic®.

Available in:
• 20 mL and 50 mL multi-dose vials.
