Abstract:
:Lung function can be reduced not only by a non-selective beta-blocker but also by a selective beta1-receptor blocker. If both types of drug are without intrinsic sympathomimetic activity, the effect of the non-selective drug is more pronounced than that of a beta1-receptor selective drug under basal conditions. The effect of a beta2-receptor stimulating drug on the bronchi is inhibited by a non-selective drug, but much less by a selective beta1-receptor blocker. A selective beta1-receptor blocker can be used in asthmatics when it is combined with optimal anti-asthmatic therapy, while a non-selective drug is contra-indicated in patients with broncho-obstructive diseases. It is necessary to induce bronchodilatation (e.g. with a beta2-stimulator) in order to test whether or not a beta-blocker can be used in broncho-obstructive disease.
