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 ]
Beta blockers vary in their lipophilicity (fat solubility) and in turn in their ability to cross the blood–brain barrier and exert effects in the central nervous system. [76] Beta blockers with greater blood–brain barrier permeability can have both neuropsychiatric therapeutic benefits and side effects, as well as adverse cognitive effects ...

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]
A 2014 meta-analysis found that unlike non-selective beta-blockers, β 1 selective beta-blockers (bisoprolol) showed only a small impact on lung function, with patients remaining responsive to salbutamol (β 2-agonist) rescue therapy and endorses the use of bisoprolol in select patients with controlled asthma.
Albuterol (Salbutamol) Has N-t-butyl and a salicyl alcohol phenyl ring which gives it optimal β2-selectivity. [14] Salbutamol is a short-acting β2-agonist, but has a rapid onset of action. [18] Its onset by inhalation is within 5 minutes. The hydroxyl group on the β-carbon is a mixture of S- and R-isomers, where the R-isomer is the active one.
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 ...
