Salbutamol or albuterol and some other β 2 agonists, such as formoterol, also are sold in a solution form for nebulization, which is more commonly used than inhalers in emergency rooms. [9] Nebulizers continuously deliver aerosolized drug and salbutamol delivered through nebulizer was found to be more effective than IV administration. [10]
Salbutamol, also known as albuterol and sold under the brand name Ventolin among others, [1] is a medication that opens up the medium and large airways in the lungs. [8] It is a short-acting β 2 adrenergic receptor agonist that causes relaxation of airway smooth muscle. [8]
Short-acting β 2-agonists are used to treat exercise-induced asthma, [7] and for asthma patients to get a quick relief of symptoms. They are taken 10–15 minutes before exercise. The bronchodilation begins few minutes after inhalation of short-acting β 2-agonists and lasts from 4 to 8 hours.
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 ]
The mechanisms of sympathomimetic drugs can be direct-acting (direct interaction between drug and receptor), such as α-adrenergic agonists, β-adrenergic agonists, and dopaminergic agonists; or indirect-acting (interaction not between drug and receptor), such as MAOIs, COMT inhibitors, release stimulants, and reuptake inhibitors that increase the levels of endogenous catecholamines.
Inhaled short-acting β2-adrenergic agonists, such as terbutaline and salbutamol, are the first-line drugs indicated for asthma exacerbation for all patients to provide rapid bronchodilating effects. [1] [2] Short-acting β2-adrenergic agonists can be delivered by different devices, for example, nebulizers and metered-dose inhalers. [2]
LABAs are designed to reduce the need for shorter-acting β 2 agonists such as salbutamol (albuterol), as they have an approximately twelve-hour duration of action, compared to about five hours for salbutamol, making them candidates for sparing high doses of corticosteroids [citation needed] or treating nocturnal asthma and providing ...
Salbutamol/budesonide, sold under the brand name Airsupra, is a fixed-dose combination medication for the treatment of bronchoconstriction and asthma. [1] [2] It is a combination of salbutamol sulfate (albuterol sulfate), a short-acting beta2-adrenergic agonist, and budesonide, an inhaled corticosteroid.
