Beta 2-agonists can be given to people in two different ways – intravenously (directly thorough a vein) and via an inhaler. Like other leukotriene receptor antagonists, zafirlukast is thought to be useful for the long-term treatment of asthma, but it is generally less effective than inhaled glucocorticoids as monotherapy (which are the standard of care) or long-acting beta-2 agonists in combination therapy. Used early, this can help keep an asthma attack from getting worse. Am J Med. Short-acting beta-2 agonists (SABAs), such as salbutamol and terbutaline, have a rapid onset of action (15 minutes) and their effects last for up to 4 hours. For example, patients with low heart rate are given beta agonist treatments that are more "cardio-selective" such as dobutamine, which increases the force of contraction of the heart muscle. Activation of adenylyl cyclase produces cyclic adenosine monophosphate (cAMP). Influence of albuterol, cromolyn sodium and ipratropium bromide on the airway and circulating mediator responses to allergen bronchial provocation in asthma. In this video we discuss the use of beta 2 agonists in the acute and prophylactic treatment of asthma. They replicate the functions of catecholamines such as epinephrine, norepinephrine, and dopamine in producing different autonomic responses within the body.
