Beta-Adrenergic Agonists
Inhaled β₂-adrenoceptor (β₂-AR) agonists are considered essential bronchodilator drugs in the treatment of bronchial asthma, both as symptoms-relievers and, in combination with inhaled corticosteroids, as disease-controllers. In this article, we first review the basic mechanisms by which the β₂-adrenergic system contributes to the control of airway smooth muscle tone. Then, we go on describing ...
متن کاملInhaled beta-2 adrenergic receptor agonists and primary cardiac arrest.
PURPOSE We sought to investigate if short-acting, inhaled beta2-adrenergic receptor agonists were associated with higher risk of primary cardiac arrest in patients with asthma or chronic obstructive pulmonary disease (COPD). SUBJECTS AND METHODS We conducted a population-based study involving 454 patients enrolled in a health maintenance organization, aged 40 to 79 years, who had asthma or CO...
متن کاملBeta-adrenergic agonists increase lung liquid clearance in anesthetized sheep.
We did experiments to determine whether beta-adrenergic agonists increase lung liquid clearance in anesthetized ventilated adult sheep and, if so, whether the increase is mediated by beta receptors and what mechanism is involved. We instilled 100 ml of autologous serum either alone or with a beta-adrenergic agonist (terbutaline, 10(-5) M, or epinephrine, 5.5 X 10(-6) M) into one lower lobe. Aft...
متن کاملMechanism of Action of Beta Adrenergic Agonists and Potential Residue Issues
Bradley J. Johnson, Ph.D. Texas Tech University Department of Animal and Food Sciences [email protected] I.β-Adrenergic Agonist-Stimulated Muscle Hypertrophy One of the most pronounced effects of feeding a β2-adrenergic agonist to ruminants is the preferential increase in skeletal muscle mass and/or cross-sectional area of individual muscles. Examples of these skeletal muscle-enhancing ch...
متن کاملDecreased insulin binding to porcine adipocytes in vitro by beta-adrenergic agonists.
The present study was conducted to determine the influence of dibutyryl-cAMP (dbcAMP), epinephrine, ractopamine and clenbuterol on insulin binding to porcine adipocytes. Dibutyryl-cAMP decreased insulin binding to swine adipocytes by 40 and 20% at 1.8 and 25.8 ng insulin/ml, respectively. Ractopamine and clenbuterol directly reduced insulin binding at the low insulin concentration and decreased...
