Katzung: Tx Asthma Flashcards
Short Acting Beta-2 agonists promoting bronchodilation
Albuterol (duration 2-4 hours)
Short acting beta agonist available PO or parenteral
Terbutaline
Adverse effects of Albuterol, the beta-2 selective agonists
Tremor, tachycardia
Metaproteranol and terbutaline are also beta 2 agonists used in the treatment of
acute asthma attack
Long Acting Beta-2 selective agonists
Salmeterol, Formoterol, Indacaterol, vilanterol
Nonselective sympathomimetics as an obsolete tx for asthma
Epinephrine, isproteronol
Indirect-acting sympathomimetic used as obsolete tx for asthma
ephedrine (releases stored catecholamines causing nonselective sympathetic effects)
Methylxanthines block _____
Phosphodiesterase 4 which increases cAMP
Methylxanthines such as theophylline have adverse effects related to increasing
Chronotropy, ionotropy, cardiac Output which can increase blood pressure and increase risk of arrythmias
Also increases gastric acid secretions, digestive enzymes
methylxanthines are also weak
diuretics leading to increased GFR and decreased Na reabsorption
Theophylline can also be toxic to the
liver
Muscurininc Antagonists end in ——- and some examples include
-tropium
ipratropium, tiotropium, aclindinum
Muscarinic antagonist that comes as a nasal spray/INH
ipratropium
Muscarinic antagonist that is used to treat asthma that has longer duration of action
Tiotropium
Muscarinic antagonist that provides bronchodilation lasting about 5 hours
atropine
