Xamoterol monotherapy in heart failure. The European 'Corwin' Group.

The effect of xamoterol as sole therapy was investigated in randomized, double-blind, placebo-controlled studies involving 425 patients with mild to moderate heart failure. When compared with placebo, 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.
