Background:
Metaproterenol is a β2-adrenergic receptor (β2-AR) agonist with bronchodilator actions. It inhibits TGF-α-induced hepatocyte DNA synthesis and proliferation in vitro (IC50 = 15 nM), an effect that is reversed by the β2-AR antagonist butoxamine but not the β1-AR antagonist metoprolol . Metaproterenol dose-dependently relaxes lung strips and increases heart rate and inotropy of right atria and left atria, respectively, isolated from guinea pig (pD2s = 6.4, 7.08, and 6.61, respectively). Formulations containing metaproterenol were previously used as long-acting bronchodilators for the treatment of asthma.
