CLINICAL PHARMACOLOGY
COMPARATIVE PHARMACOLOGY
In animals, butorphanol has been demonstrated to be 4 to 30 times more
potent than
morphine and pentazocine (Talwin -V) respectively.
In humans, butorphanol has been
shown to have 5 to 7 times the analgesic activity of morphine and 20
times that of
pentazocine.
Butorphanol has 15 to 20 times the oral antitussive activity of
codeine or
dextromethorphan in dogs and guinea pigs.
As an antagonist, butorphanol is approximately equivalent to
nalorphine and 30 times
more potent than pentazocine.
Cardiopulmonary depressant effects are minimal after treatment with
butorphanol as
demonstrated in dogs,
humans
and horses.
Unlike classical narcotic agonist
analgesics which are associated with decreases in blood pressure,
reduction in heart

rate, and concomitant release of histamine, butorphanol does not cause
histamine
release.
Furthermore, the cardiopulmonary effects of butorphanol are not
distinctly
dosage related but rather reach a ceiling effect beyond which further
