Fenoterol is a β adrenoreceptor agonist.It is classed as sympathomimetic β 2 agonist and an inhaled bronchodilator asthma medication.. Fenoterol is produced and sold by Boehringer Ingelheim as Berotec N and in combination with ipratropium as Berodual N.
An anti-asthmatic agent, also known as an anti-asthma drug, refers to a drug that can aid in airway smooth muscle dilation to allow normal breathing during an asthma attack or reduce inflammation on the airway to decrease airway resistance for asthmatic patients, or both. The goal of asthmatic agents is to reduce asthma exacerbation frequencies ...
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 ...
Budesonide/formoterol, sold under the brand name Symbicort among others, is a fixed-dose combination medication used in the management of asthma or chronic obstructive pulmonary disease (COPD). [2] It contains budesonide , a steroid ; and formoterol , a long-acting β 2 -agonist (LABA). [ 2 ]
While some studies suggest that there are minimal differences in side effects between asthma patients and non-asthma patients, beta 1 blockers are generally avoided in patients with asthma or chronic obstructive pulmonary disease due to their potential to block beta 2 receptors, particularly at high doses.
Serious side effects may include worsening asthma, anaphylaxis, seizures, and heart problems. [5] Safety in pregnancy and breastfeeding is unclear. [ 6 ] Fluticasone, a corticosteroid , works by decreasing inflammation while salmeterol, a long-acting beta-adrenoceptor agonist (LABA), works by activating beta-2 adrenergic receptors .
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 ...
The combination of beta blockers and antihypertensive drugs will work on different mechanism to lower blood pressure. [17] For example, the co-administration of beta-1 blocker atenolol and ACE inhibitor lisinopril could produce a 50% larger reduction in blood pressure than using either drug alone.
