sorts of bronchodilator
The 3 most broadly used bronchodilators are:
beta-2 agonists – such as salbutamol, salmeterol, formoterol and vilanterol
anticholinergics – which include ipratropium, tiotropium, aclidinium and glycopyrronium
Beta-2 agonists and anticholinergics are to be had in each brief-appearing and long-appearing bureaucracy, whereas theophylline is best to be had in an extended-appearing shape.
Beta-2 agonists
Beta-2 agonists are used for each bronchial asthma and COPD, even though some sorts are only available for COPD. they're normally inhaled the use of a small, handheld inhaler but may also be available as tablets or syrup.
For sudden, severe signs they also can be injected or nebulised. A nebuliser is a compressor used to show liquid medicine right into a first-class mist, allowing a massive dose of the drugs to be inhaled through a mouthpiece or face mask.
Beta-2 agonists paintings by using stimulating receptors known as beta-2 receptors inside the muscles that line the airlines, which causes them to loosen up and lets in the airlines to dilate (widen).
