Beta 2-adrenergic agonists, also known as adrenergic β 2 receptor agonists, are a class of drugs that act on the β 2 adrenergic receptor. Like other β adrenergic agonists , they cause smooth muscle relaxation. β 2 adrenergic agonists' effects on smooth muscle cause dilation of bronchial passages , vasodilation in muscle and liver ...
Fenoterol is a β adrenoreceptor agonist.It is classed as sympathomimetic β 2 agonist and an inhaled bronchodilator asthma medication.. Fenoterol is produced and sold by Boehringer Ingelheim as Berotec N and in combination with ipratropium as Berodual N.
β 2-adrenoceptor agonists are a group of drugs that act selectively on β 2-receptors in the lungs causing bronchodilation. β 2-agonists are used to treat asthma and COPD, diseases that cause obstruction in the airways. Prior to their discovery, the non-selective beta-agonist isoprenaline was used.
When combined with inhaled steroids, β adrenoceptor agonists can improve symptoms. [1] [2] In children this benefit is uncertain and they may be potentially harmful. [2]They should not be used without an accompanying steroid due to an increased risk of severe symptoms, including exacerbation in both children and adults. [3]
Beta adrenergic agonists or beta agonists are medications that relax muscles of the airways, causing widening of the airways and resulting in easier breathing. [1] They are a class of sympathomimetic agents, each acting upon the beta adrenoceptors . [ 2 ]
Formoterol, also known as eformoterol, is a long-acting β 2 agonist (LABA) used as a bronchodilator in the management of asthma and chronic obstructive pulmonary disease (COPD). Formoterol has an extended duration of action (up to 12 h) compared to short-acting β 2 agonists such as salbutamol (albuterol), which are effective for 4 h to 6 h.
Zafirlukast is FDA-approved for the prevention and treatment of asthma in adults and children older than 5 years old. [1] Like other leukotriene receptor antagonists, zafirlukast is thought to be useful for the long-term treatment of asthma, but it is generally less effective than inhaled glucocorticoids as monotherapy (which are the standard of care) or long-acting beta-2 agonists in ...
Additionally, beta 1 blockers can affect beta 2 receptors, particularly at high doses, and hence should not be administered to patients with peripheral vascular disease or diabetes mellitus as they may cause vasoconstriction or a delayed hypoglycaemic response, respectively. [4]
