Terbutaline sulfate is a fast-acting beta-2 adrenergic agonist used to relieve bronchospasm in asthma, COPD, and other respiratory conditions. It works by relaxing the airway muscles, making breathing easier. Terbutaline is available in tablet (2.5 mg, 5 mg), injection (1 mg/mL), and inhaler forms. In the EU, it's marketed as Bricanyl, while in the US, generic versions are available. Terbutaline provides quick relief from breathing difficulties and is sometimes used off-label as a tocolytic to delay premature labor. Common side effects include tremor and palpitations. It is a valuable option in respiratory emergency and maintenance therapy.
