Terms in this set (139)
Agent that stimulates sympathetic nervous fibers, which allow relaxatio of smooth muscle in the airway; a.k.a. sympathomimetic bronchodilator or beta-2-agonist
Causes vasoconstriction and vasopressor effect; in the upper airway (nasal passages), this can provide decongestion.
Refers to increasing incidence of asthma morbidity, and especially asthma mortality, despite advances in the understanding of asthma and availability of improved drugs to treat asthma.
Causes increased myocardial conductivity, heart rate, and contractile force.
Causes relaxation of bronchial smooth muscle, with some inhibition of inflammatory mediator release and stimulation of mucociliary clearance.
Narrowing of the bronchial airways caused by contraction of smooth muscle.
group of similar compounds having sympathomimetic action; they mimic the actions of epinephrine.
Nucleotide produced by beta-2-receptor stimulation; it affects may cells, but it causes relaxation of bronchial smooth muscle.
cyclic adenosine 3', 5'-monophosphate (cAMP)
Long-term desensitization of beta receptors to beta-2 agonists caused by a reduction in the number of beta receptors.
Producing effects similar to those of the sympathetic nervous system.
Agent that blocks parasympathetic nervous fibers, allowing relaxation of smooth muscle in the airway.
Same as anticholinergic bronchodilator--agent that blocks the effect of acetylcholine (Ach) at the cholinergic site.
Agent that produces the effect of Ach.
Same as cholinergic--agent that produces the effect of Ach or an agent that mimics Ach.
Blocking parasympathetic nervous fibers
