Terbutaline API

Terbutaline is a selective beta-2 adrenergic receptor agonist. Agonism of these receptors in bronchioles activates adenylyl cyclase, increasing intracellular cyclic adenosine monophosphate (cAMP).

419.2 °C

Molecular Weight :

225.284 g/mol

Density :

N/A

Solubility :

Terbutaline sulfate is soluble at 1 g per 1.5 ml water or 250 ml of ethanol. It is soluble in 0.1 N hydrochloric acid, slightly soluble in methanol, and insoluble in chloroform. While terbutaline is stable under normal conditions as a solid, it is unstable in light.

Uses :


  • Terbutaline is used to prevent and treat wheezing, shortness of breath, and chest tightness caused by asthma, chronic bronchitis, and emphysema. Terbutaline is in a class of medications called beta agonists. It works by relaxing and opening the airways, making it easier to breathe.
