DESCRIPTION
Terbutaline sulfate USP is a beta-adrenergic agonist bronchodilator
available as tablets of 2.5 mg (2.05
mg of the free base) and 5 mg (4.1 mg of the free base) for oral
administration. Terbutaline sulfate is ±-
α-[(_tert_ –butylamino) methyl]-3,5-dihydroxybenzyl alcohol sulfate
(2:1) (salt). The molecular formula is
(C
H NO ) • H SO and the structural formula is
Terbutaline sulfate USP is a white to gray-white crystalline powder.
It is odorless or has a faint odor of
acetic acid. It is soluble in water and in 0.1N hydrochloric acid,
slightly soluble in methanol, and
insoluble in chloroform. Its molecular weight is 548.65.
_Inactive Ingredients:_ microcrystalline cellulose, anhydrous lactose,
magnesium stearate, povidone, and
pregelatinized corn starch.
CLINICAL PHARMACOLOGY
In vitro and in vivo pharmacologic studies have demonstrated that
terbutaline exerts a preferential effect
on beta -adrenergic receptors. While it is recognized that beta
-adrenergic receptors are the
predominant receptors in bronchial smooth muscle, data indicate that
there is a population of beta -
receptors in the human heart, existing in a concentration between
10%-50%. The precise function of
these receptors has not been established (see WARNINGS). In controlled
clinical studies in patients
given terbutaline sulfate orally, proportionally greater changes
occurred in pulmonary function
parameters than in heart rate or blood pressure. While this suggests a
relative preference for the beta -
receptors in man, the usual cardiovascular effects commonly associated
with other sympathomimetic
agents were also observed with terbutaline sulfate.
The pharmacologic effects of beta-adrenergic agonists, including
terbutaline, are at least in part
attributable to stimulation through beta-adrenergic receptors of
intracellular adenyl cyclase, the enzyme
which catalyzes the conversion of adenosine triphosphate (ATP)
