Beta-2-adrenoreceptor (beta-2) agonists are drugs that act as bronchodilators. The drugs stimulate the airways in the lungs (bronchi) to open wider, permitting more air to pass. The drugs are especially helpful to asthmatics, who can suffer from insufficient air supply to the lungs due to narrowing of the bronchi.

A beta 2 agonist may also be given by mouth but administration by inhalation is preferred; a long-acting inhaled beta 2 agonist may be used where appropriate. In severe attacks nebulisation using a selective beta 2 agonist or ipratropium bromide is advisable.

Selective β2 agonist. The prime action of beta-adrenergic drugs is to stimulate adenyl cyclase, the enzyme which catalyzes the formation of cyclic AMP from ATP. cAMP mediates the cellular responses The prime action of beta-adrenergic drugs is to stimulate adenyl cyclase, the enzyme which catalyzes the formation of cyclic AMP from ATP. cAMP

Beta-adrenergic agonist Beta adrenergic agonists or beta agonists are medications that relax muscles of the airways, which widen the airways and result in easier breathing. [1] They are a class of sympathomimetic agents which act upon the beta adrenoceptors . [2]

Selektiva beta-2-stimulerare (β2-stimulerare), eller beta-2-agonister (β2-agonister), är en grupp läkemedel som vidgar luftrören (bronkdilaterande), vilket minskar symtomen vid astma och KOL. Läkemedlen fungerar genom stimulering av β2-receptorer , vilket häver sammandragningen av luftrörens muskler och därmed vidgas luftrören.

2-Agonist Review Overview Beta 2-agonist bronchodilators are used for the treatment and prevention of bronchospasm associated with asthma, prophylaxis of exercise-induced bronchospasm (EIB), and in the treatment of chronic obstructive pulmonary disease (COPD). The mainstay of asthma therapy is the use of inhaled glucocorticoids and long-acting

beta-agonist in full beta ( β )-adrenoceptor (-adrenergic) agonist a sympathomimetic drug that stimulates β-adrenoceptors. Subgroup β 2 agonists are used in asthma, usually by inhalation, to dilate the airways by relaxing smooth muscle, acting as a ‘reliever’ …

Beta agonists were developed through modifications of the epinephrine molecule to allow selective interaction with the beta-1 and beta-2 receptors (eg, isoproterenol), rather than the combined alpha and beta effects of epinephrine.

Cyanopindolol is a high-affinity antagonist at both beta-1 and beta-2 adrenergic receptors and is a partial agonist at beta-3 adrenergic receptors in rat colon and the atypical cardiostimulant beta-adrenergic receptor in rat and human atria (Kaumann and Molenaar, 1996).

Definition (NCI) A highly selective, long-acting beta-2 adrenergic agonist with bronchodilatory activity. Salmeterol’s benzene moiety resembles the structure of catecholamines, and occupies the active site of beta-2 adrenergic receptor, while the long, lipophilic side chain of salmeterol, binds to the so called ‘exosite’ near the beta-2 adrenergic receptors.

Medscape’s clinical reference is the most authoritative and accessible point-of-care medical reference for physicians and healthcare professionals, available online and via all major mobile devices.

Adrenergic receptors respond to sympathetic stimulation and blood-borne epinephrine. Receptors are located on smooth muscle, cardiac pacemaker, myocardium and glands. Stimulatory subtypes are alpha 1 and beta 1; inhibitory subtypes are alpha 2, beta 2 &3.

The adrenergic β 2 receptor (β 2-adrenoceptor) is a member of the adrenergic receptor group of G-protein-coupled receptors that also includes α 1A, α 1B, α 1D, α 2A, α 2B, α 2C, β 1 and β 3. They are located primarily in the CNS, heart, kidney and muscle where they are involved in smooth muscle relaxation (e.g. bronchodilation).

Inhaled short-acting beta 2-agonists (SABAs) should be prescribed as rescue medications for all patients with asthma or COPD who tolerate them. Patients with COPD are often prescribed an inhaled short-acting or long-acting anticholinergic agent.

Although decrease in HR plays a role, one of the main ways how beta-blockers decrease BP is by inhibiting Renin production in the kidney (recall: Renin producing JGA-cells have beta-1 receptors) –> decrease in ATII (one of the most potent vasoconstrictors) and

Beta 2-Agonist Selectivity The goal of beta 2-adrenergic agents is to provide bronchodilation and yet avoid the adverse effects induced by stimulation of alpha- and beta 1-receptors. In most cases, beta 2-agonist activity does not lead to adverse effects. However, selectivity does not circumvent all risks.
