Pirbuterol is a beta-2 adrenergic bronchodilator. In vitro studies and in vivo pharmacologic studies have demonstrated that pirbuterol has a preferential effect on beta-2 adrenergic receptors compared with isoproterenol. While it is recognized that beta-2 adrenergic receptors are the predominant receptors in bronchial smooth muscle, data indicate that there is a population of beta-2 receptors in the human heart, existing in a concentration between 10-50%. The precise function of these receptors has not been established.
The pharmacologic effects of beta adrenergic agonist drugs, including pirbuterol, are at least in proof attributable to stimulation through beta adrenergic receptors of intracellular adenyl cyclase, the enzyme which catalyzes the conversion of adenosine triphosphate (AlP) to cyclic-3† ,5†-adenosine monophosphate (c-AMP). Increased c-AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.

PIRBUTEROL
Mechanisms of Action [MoA] - Adrenergic beta2-Agonists
Established Pharmacologic Class [EPC] - beta2-Adrenergic Agonist
Pirbuterol is a beta2-Adrenergic Agonist. The mechanism of action of pirbuterol is as an Adrenergic beta2-Agonist.
Agents that cause an increase in the expansion of a bronchus or bronchial tubes.
Agents that have a strengthening effect on the heart or that can increase cardiac output. They may be CARDIAC GLYCOSIDES; SYMPATHOMIMETICS; or other drugs. They are used after MYOCARDIAL INFARCT; CARDIAC SURGICAL PROCEDURES; in SHOCK; or in congestive heart failure (HEART FAILURE).
Compounds bind to and activate ADRENERGIC BETA-2 RECEPTORS.
DescriptionPirbuterol is a β2-agonist in the management of disorders with reversible airways obstruction. It is given by inhalation and orally.
UsesThis relatively selective β2-adrenergic receptor agonist is structurally very similar to albuterol, and it displays similar broncholytic properties. It is used as an inhaled drug for treating bronchial asthma.
UsesBronchodilator.
DefinitionChEBI: Pirbuterol is a member of pyridines.
