Description

Arbutamine was indicated to elicit acute cardiovascular responses in order to aid in diagnosing the presence or absence of coronary artery disease in patients who cannot exercise adequately. Arbutamine is a synthetic catecholamine with positive chronotropic and inotropic properties. The chronotropic (increase in heart rate [HR]) and inotropic (increase in force of contraction) effects of arbutamine serve to mimic exercise by increasing cardiac work (producing stress) and provoke myocardial ischemia in patients with compromised coronary arteries. In functional assays, arbutamine is more selective for beta-adrenergic receptors than for alpha-adrenergic receptors. The beta-agonist activity of arbutamine provides cardiac stress by increasing HR, cardiac contractility, and systolic blood pressure.

In Vitro Use Guide

It was characterized the interactions of arbutamine with different adrenergic receptor subtypes in vitro. In the electrically stimulated left atria of rats, arbutamine increased contractile force. The pD2 values (- log of the dose that produces 50% of the maximal responses) for arbutamine and isoproterenol were 8.45 +/- 0.15 and 8.55 +/- 0.02, respectively. Both arbutamine and isoproterenol increased the rate of spontaneously beating rat right atria with pD2 values of 9.0 +/- 0.19 and 8.82 +/- 0.18, respectively. The affinity constants (KA) of arbutamine and isoproterenol for cardiac beta1-adrenergic receptors, as determined by competition binding assays, were found to be 7.32 and 6.04, respectively. In guinea pig trachea, arbutamine and isoproterenol produced a concentration-dependent relaxation that was blocked by propranolol. Their pD2 values were 7.9 +/- 0.1 and 8.2 +/- 0.1, respectively. Arbutamine contracted isolated rat aortic rings with a maximal increase of 38.1 +/- 6.7% that of 10 microM of norepinephrine. In rat white adipocytes, arbutamine, isoproterenol, and BRL-37344 stimulated glycerol release, with the order of potency being BRL-37344 > arbutamine > isoproterenol. In hamster brown adipocytes, the order was arbutamine > isoproterenol > BRL-37344. Moreover, arbutamine stimulated beta3-adrenergic receptors in guinea pig ileum. Arbutamine does not stimulate alpha-adrenergic receptors at concentrations that were high enough to maximally activate the beta-adrenergic receptors.
