Use of beta-adrenoreceptor blockers in combination with beta-stimulators in patients with obstructive lung disease

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.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
