Arbutamine hydrochloride is a short-acting, potent and nonselective β-adrenoceptor agonist. Arbutamine hydrochloride stimulates cardiac β1-, tracheal β2-, and adiopocyte β3- adrenergic receptors. Arbutamine hydrochloride provides cardiac stress increases heart rate, cardiac contractility, and systolic blood pressure. Arbutamine hydrochloride can be used for cardiac stress agent [1][2][3].

In Vitro	Arbutamine hydrochloride (0.1-100 nM) increases heart contractile force and pD2 value of 8.45. Arbutamine has the affinity constants (KA) value of 7.32 for cardiac β1-adrenergic receptors[3].
In Vivo	Arbutamine hydrochloride (i.v.; 5, 10, 50, 100 and 250 ng/kg) increases mean heart rate, peak positive left ventricular pressure and its first time-derivative, and normal-zone myocardial thickening in 8 open-chest dogs (mean weight, 26.91 kg).
