adrenergic bronchodilator

adrenergic bronchodilator

a drug that acts on the beta-2 sympathetic nervous system of the receptors to relax bronchial smooth muscle cells. Examples include drugs that contain epINEPHrine, epHEDrine, isoproterenol hydrochloride, or albuterol.

Adrenergic Bronchodilator

An often aerosolised drug used to dilate bronchial lumina and reduce airway resistance in patients with asthma and chronic bronchitis.
Examples Adrenaline (epinephrine), albuterol (Proventil, Ventolin), arformoterol, bitolterol (Tornolate), ephedrine, epinephrine (adrenaline), formoterol (Perforomist), isoetharine, isoproterenol, levalbuterol, metaproterenol, pirbuterol (Maxair), racepinephrine, ritodrine, salmeterol, terbutaline (Brethine), theophylline.
Adverse effects Dyspnoea, tachypnoea, apnoea, hypertension, tachycardia, convulsions, coma, fever, tremor, cyanosis, nausea, vomiting, blurred vision.
