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.
