Terbutaline is a potent and selective β2-adrenergic receptor agonist with IC50 of 53 NM, it has little or no effect on alpha-adrenergic receptors. The drug has exerts a preferential effect on β2-adrenergic receptors but stimulates beta-adrenergic receptors less selectively than relatively selective beta2-agonists. Terbutaline inhibits antigen-induced histamine release from passively sensitized human lung tissue, which contributes to the clinical effectiveness of the drug during treatment of allergic asthma.
