Abstract
Considering the beta-3 adrenoceptor agonist, mirabegron, may display vasodilator and cardioprotective properties, we investigated the therapeutic potential of mirabegron in monocrotaline-induced pulmonary hypertension in rats. High-dose mirabegron improved right ventricular function, and endothelium-dependent relaxation in isolated rat pulmonary arteries, suggesting that mirabegron may be beneficial in pulmonary arterial hypertension.
