DESCRIPTION
Butorphanol tartrate, is a synthetic, centrally acting, narcotic
agonist-antagonist analgesic with potent
antitussive activity. The results from laboratory and clinical studies
suggest the existence of several
distinct types of receptors that are responsible for the activity of
opioid and opioid-like drugs. When
activated, the _μ_(mu)-receptors are involved in analgesia,
respiratory depression, miosis, physical
dependence and feelings of well-being (euphoria). When activated, the
_κ_(kappa)-receptors are involved
in analgesia, as well as less intense (as compared to _μ_-receptors)
miosis and respiratory depression.
Butorphanol is considered to be a weak antagonist at the
_μ_-receptor, but a strong agonist at the _κ_-
receptor. Thus, butorphanol provides analgesia with a lower incidence
and/or intensity of adverse
reactions (e.g., miosis and respiratory depression) than traditional
opioids.
Butorphanol tartrate is a member of the phenanthrene series. The
chemical name is Morphinan-3, 14-
diol, 17-(cyclobutylmethyl)-, (-)-, (S- (R*, R*))- 2,3-
dihydroxybutanedioate (1:1) (salt). It is a white,
crystalline, water soluble substance having a molecular weight of
477.55; its molecular formula is
C21H29NO2• C4H6O6.
CHEMICAL STRUCTURE
Each mL of TORBUGESIC-SA contains 2 mg butorphanol base (as
butorphanol tartrate, USP); 3.3 mg
citric acid, USP; 6.4 mg sodium citrate, USP; 4.7 mg sodium chloride;
and 0.1 mg benzethonium

CLINICAL PHARMACOLOGY
FELINE PHARMACOLOGY
The magnitude and duration of analgesic activity of butorphanol were
studied in cats under controlled
laboratory conditions using both a visceral pain model and a somatic
pain model.1,2 Subcutaneous
