Paradoxical bronchoconstriction caused by β2-adrenoceptor agonists

Drug Target Insights, 2020
Introduction: Salbutamol and terbutaline are short-acting β2 adrenergic agonists that produce bronchial smooth muscle relaxation and are widely used in obstructive pulmonary diseases.

Associations Between Asthma and Device‐Based Measured Physical Activity Among Children and Adolescents: The Lolland–Falster Health Study

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Aim The aim of this study was to examine whether asthma in children and adolescents is associated with a difference in physical activity (PA) both regarding intensity (sedentary, light, moderate‐vigorous) and behaviour (lying, sitting, standing, walking, running and biking).

Bronchoconstriction: upper airway dilating muscle and diaphragm activity

, 1983
The effect of bronchoconstriction on the activity of the diaphragm and the upper dilating airway muscles were studied by administering graded doses of methacholine to anesthetized dogs spontaneously breathing oxygen.

Neurally mediated airway constriction in human and other species: a comparative study using precision-cut lung slices (PCLS). [PDF]

PLoS ONE, 2012
The peripheral airway innervation of the lower respiratory tract of mammals is not completely functionally characterized. Recently, we have shown in rats that precision-cut lung slices (PCLS) respond to electric field stimulation (EFS) and provide a ...

Neurokinin receptors subserving bronchoconstriction

, 1995
Tachykinin receptor subtypes were initially defined using agonist potency ratios for the endogenous ligands substance P (SP), neurokinin (NK) A, and NKB. On this basis it was suggested that there are three tachykinin receptor subtypes.

Perception of dyspnea during exercise-induced bronchoconstriction [PDF]

, 2003
After strenuous physical exercise, many subjects show a significant bronchoconstriction and report dyspnea. Despite this clinical condition being a commonly encountered situation during daily life, which may be responsible for substantial disability ...

Electrophysiological properties of the dorsal motor nucleus of the vagus motoneurones controlling airway mucus secretion in rats

The Journal of Physiology, EarlyView.
Abstract figure legend Acidosis depolarises parasympathetic respiratory motoneurones in the dorsal motor nucleus of the vagus (DMV) and increases their firing frequency by reducing TWIK‐2 channel conductance. Acidosis also activates astrocytes, which further enhance neuronal excitability through NMDA receptor‐dependent glutamatergic signalling.

The effect of the tachykinin NK2 receptor antagonist MEN11420 (nepadutant) on neurokinin A-induced bronchoconstriction in asthmatics

Therapeutic Advances in Respiratory Disease, 2009
Objective: We previously reported that the nonpeptide tachykinin NK 2 receptor antagonist SR48968 (saredutant) significantly inhibits neurokinin A-induced bronchoconstriction in patients with asthma. MEN11420 (nepadutant) is a bicyclic peptide tachykinin
