Xamoterol (ICI 118,587) is a partial agonist of beta1-adrenoceptors. Xamoterol acts on the cardiac beta 1-adrenergic receptor, modifies the response of the heart to variations in sympathetic activity. At rest, it produces modest improvements in cardiac contractility, relaxation, and filling without increase in myocardial oxygen demand. The improvements are maintained during exercise although the attendant tachycardia is attenuated. The beneficial effects of xamoterol on both systolic and diastolic function suggested that it would be effective in patients with mild-to-moderate heart failure, and this was demonstrated in small placebo-controlled studies where effort tolerance and symptoms were improved. Xamoterol produced improvements in exercise capacity, clinical signs, symptoms and quality of life with a low incidence of adverse experiences. Xamoterol is effective as monotherapy in heart failure.

Sample Use Guides

In Vivo Use Guide

Xamoterol at 200 mg and 400 mg orally once daily had no effect on the mean resting heart rate but there was a small (5.7 beats min-1) but significant reduction in resting heart rate on 600 mg at 2-2.5 h after dosing. All three doses of xamoterol significantly reduced the maximum exercise heart rate at 2-2.5 h after dosing. Xamoterol at all three doses significantly increased exercise duration at 2-2.5 h after dosing but not at 24 h.

Route of Administration: Oral

In Vitro Use Guide

human microvascular retinal endothelial cells (HMREC) cultured in high (25 mM) and low glucose (5 mM) conditions were serum starved for 18-24 h, followed by treatment with a beta-1-adrenergic receptor agonist, xamoterol (10 microM), for 15, 30, and 45 min.
