Abbreviated New Drug Application
TERBUTALINE SULFATE - TERBUTALINE SULFATE TABLET STATE OF FLORIDA DOH CENTRAL PHARMACY ---------- TERBUTALINE SULFATE TABLETS USP RX ONLY 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 trip Đọc toàn bộ tài liệu
