2. Beta2-adrenergic agonist - Wikipedia

   en.wikipedia.org/wiki/Beta2-adrenergic_agonist

   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 ...

3. Salbutamol - Wikipedia

   en.wikipedia.org/wiki/Salbutamol

   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 ]

4. Beta-adrenergic agonist - Wikipedia

   en.wikipedia.org/wiki/Beta-adrenergic_agonist

   They are a class of sympathomimetic agents, each acting upon the beta adrenoceptors. [2] In general, pure beta-adrenergic agonists have the opposite function of beta blockers: beta-adrenoreceptor agonist ligands mimic the actions of both epinephrine- and norepinephrine- signaling, in the heart and lungs, and in smooth muscle tissue; epinephrine ...

   The classification of drugs have been around since 1964 after Sir James Black discovered how they can assist people with heart disease.

6. Beta-2 adrenergic receptor - Wikipedia

   en.wikipedia.org/wiki/Beta-2_adrenergic_receptor

   The beta-2 adrenergic receptor (β 2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that binds epinephrine (adrenaline), a hormone and neurotransmitter whose signaling, via adenylate cyclase stimulation through trimeric G s proteins, increases cAMP, and, via downstream L-type calcium channel interaction, mediates physiologic responses such as smooth ...

7. Adrenergic blocking agent - Wikipedia

   en.wikipedia.org/wiki/Adrenergic_blocking_agent

   Beta 2 blockers cease action of beta-2 receptor by blocking the receptor and preventing it from being activated. [6] Similar to beta-1 receptor, the activated beta-2 receptor will lead to the detach of alpha subunit of Gs protein and attachment of adenylate cyclase. [6] Adenosine triphosphate(ATP), is then catalyzed to form cAMP.

8. Long-acting beta-adrenoceptor agonist - Wikipedia

   en.wikipedia.org/wiki/Long-acting_beta...

   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 ...

   Concomitant use of calcium channel blockers and magnesium sulfate may result in cardiovascular collapse [28] Calcium channel blockers have the fewest neonatal adverse effects [5] Atosiban: Oxytocin receptor antagonist Safer than both nifedipine and beta agonists; As effective as nifedipine and more effective than beta agonists.
