Description and Uses
Terbutaline is the N-t-butyl analogue of metaproterenol and, as such, would be expected to have a more potent β2-selectivity. When compared to metaproterenol, terbutaline has a threefold greater potency at the β2-receptor. Like metaproterenol, it is resistant to COMT and slowly metabolized by MAO, therefore having good oral bioavailability with similar onset and duration. Terbutaline is available as tablets and solutions for injection and inhalation. Adverse effects are similar to other direct-acting β2-selective agonists, however, with a greater incidence of palp
