PHARMACOLOGICAL ACTION: It has affinity for mu receptors acting as a competitive antagonist, but it exerts its anesthetic action acting as an agonist at kappa receptors.

INDICATIONS: For reversible narcosis in white-tailed deer (Odocoileus virginianus), black bear (Ursus americanus), white rhinoceros (Ceratotherium simum), black rhinoceros (Diceros bicornis) and African lion (Panthera leo).


CONTRAINDICATIONS: It should not be used in animals for human consumption or in animals hypersensitive to butorphanol tartrate. Do not use during pregnancy and lactation.

PRECAUTIONS: Administer with caution in animals with liver and / or kidney problems (if required, use half of the suggested doses), animals with cardiac problems or with head trauma, elevated intracranial pressure or some other CNS dysfunction due to the probable association with an increase in CO2 retention and the consequent elevation of the pressure of the cerebrospinal fluid. The effects of miosis or altered states of consciousness produced by the drug interfere with the neurological evaluation of patients with head trauma.

WITHDRAWAL PERIOD: Butonil 30X should not be used in animals for human consumption, therefore no withdrawal period is established.
