Effect of Thyroxine was studied in histamine induced bronchospasm in guinea pigs. Chronic treatment with the drug significantly protected against experimental bronchospasm. Thyroxine also potentiated salbutamol evoked bronchodilation in this experimental model. Up-regulation of beta-2 adrenoceptors in bronchial smooth muscle may be the probable mechanism of action of thyroxine.
Indacaterol is the first of a new category of inhaled b2-agonists with a very long duration of action that allows for once-daily administration. The bronchodilation induced by indacaterol is more persistent than that caused by the current long-acting b2-agonists (LABAs; salmeterol and formoterol), and therefore, for this new compound, the word ‘ultra-LABA’ has been created. Indacaterol is an ag...
The natural history of lung hyperinflation in patients with airway obstruction is unknown. In particular, little information exists about the extent of air trapping and its reversibility to bronchodilator therapy in those with mild airway obstruction. We completed a retrospective analysis of data from individuals with airway obstruction who attended our pulmonary function laboratory and had ple...
BACKGROUND Data are lacking from general population studies on how to define changes in lung function after bronchodilation. This study aimed to analyze different measures of bronchodilator response of forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and slow vital capacity (SVC). MATERIALS AND METHODS Data were derived from the Swedish Cardiopulmonary Bioimage Study (...
OBJECTIVE Overuse of short-acting bronchodilators is internationally recognised as a marker of poor asthma control, high healthcare use and increased risk of asthma death. Young adults with asthma commonly overuse short-acting bronchodilators. We sought to determine the reasons for overuse of bronchodilator inhalers in a sample of young adults with asthma. DESIGN Qualitative study using a pur...
