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]
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]
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 ]
Fenoterol is a short-acting β 2 agonist that also stimulates β 1 receptors. Fenoterol has more cardiovascular toxicity than isoprenaline or salbutamol. Fenoterol has more cardiovascular toxicity than isoprenaline or salbutamol.
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]
In the mid-1960s, albuterol or salbutamol was discovered, followed by tributalin and fenoterol a few years later. Albuterol and terbutaline gave fewer side effects, such as increased heart rate, than isoproterenol. The pharmaceutical company Glaxo discovered salmeterol, a long-acting β 2-agonist that had bronchodilation activity for up to 12 ...
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.
Levosalbutamol acts as a functional agonist that relaxes the airway irrespective of the spasmogen involved, thereby protecting against all bronchoconstrictor challenges. While it is recognized that β 2 adrenergic receptors are the predominant receptors on bronchial smooth muscle, data indicate that there are beta receptors in the human heart ...
