2. Beta blocker - Wikipedia

   en.wikipedia.org/wiki/Beta_blocker

   Beta blockers are used to treat acute cardiovascular toxicity (e.g. in overdose) caused by sympathomimetics, for instance caused by amphetamine, methamphetamine, cocaine, ephedrine, and other drugs. [38] Combined α 1 and beta blockers like labetalol and carvedilol may be more favorable for such purposes due to the possibility of "unopposed α ...

3. 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.

4. Bisoprolol - Wikipedia

   en.wikipedia.org/wiki/Bisoprolol

   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.

5. 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 ...

6. Adrenergic neuron blockers - Wikipedia

   en.wikipedia.org/wiki/Adrenergic_neuron_blockers

   Beta 2 blockers primarily contract the smooth muscles in various tissues, particularly airway smooth muscles where beta 2 receptors are predominantly present. [5] There are currently no FDA-approved beta 2 antagonists for clinical uses. Butoxamine, an example of a beta 2 blocker, is only used in research. [5]

7. Discovery and development of beta-blockers - Wikipedia

   en.wikipedia.org/wiki/Discovery_and_development...

   The β-blockers are an immensely important class of drugs due to their high prevalence of use. The discovery of β-blockers reaches back to more than 100 years ago, when early investigators came up with the idea that catecholamines were binding selectively to receptor-like structures and that this was the cause of their pharmacological actions.
