Asthma Flashcards
What is the class for Albuterol; Terbutaline; Metoproterenol; Pirbutal
Bronchodilator - short-acting ?2 agonist)
What is the mechanism for Albuterol; Terbutaline; Metoproterenol; Pirbutal
Relax bronchial smooth muscle, inhibit mediator release (mast cells, basophils), increase mucociliary clearance, suppression of microvascular permeability
What are the therapeutics for Albuterol; Terbutaline; Metoproterenol; Pirbutal
Prevent or reduce exercise-induced bronhospasms; mild asthma & acute exacerbations
What are the important side effects for Albuterol; Terbutaline; Metoproterenol; Pirbutal
Musculoskeletal tremor, Tachycardia, hyperglycemia, hypokalemia, hypomagnesemia
What are the other side effects for Albuterol; Terbutaline; Metoproterenol; Pirbutal
Tolerance with chronic use, Prolonged QTc, lactic acidosis, paradoxical bronchospasm
What are the miscellaneous for Albuterol; Terbutaline; Metoproterenol; Pirbutal
5 minutes to take action, 4-6 hours duration; nebulizer delivers more, but greater side effects. Note: Levalbuterol is R-isomer of albuterol.
What is the class for Salmeterol (Serevent); Formoterol; Indacaterol
Bronchodilator - long-acting ?2 agonist
What is the mechanism for Salmeterol (Serevent); Formoterol; Indacaterol
Relax bronchial smooth muscle, inhibit mediator release (mast cells, basophils), increase mucociliary clearance, suppression of microvascular permeability
What are the therapeutics for Salmeterol (Serevent); Formoterol; Indacaterol
used for long-term control of asthma symptoms (always in comination with inhaled steroids)
What are the important side effects for Salmeterol (Serevent); Formoterol; Indacaterol
Musculoskeletal tremor, Tachycardia, hyperglycemia, hypokalemia, hypomagnesemia
What are the other side effects for Salmeterol (Serevent); Formoterol; Indacaterol
Tolerance with chronic use, Prolonged QTc, lactic acidosis, paradoxical bronchospasm
What are the miscellaneous for Salmeterol (Serevent); Formoterol; Indacaterol
10-15 minutes to take action, 6-12 hours (max) of duration; nebulizer delivers more, but greater side effects; oral is least effective (requires more dose –> side effects); can be used night symptoms, but not ideal
What is the class for Theophylline (Theolair); Theobromine; Caffeine
Bronchodilator (Methylxanthine)
What is the mechanism for Theophylline (Theolair); Theobromine; Caffeine
Phosphodiesterase inhibition and enhanced signalling via increased cAMP and cGMP; relax bronchial smooth muscle
What are the therapeutics for Theophylline (Theolair); Theobromine; Caffeine
Reduce inflammation and bronchospasm in moderate to severe asthma, night symptoms
What are the important side effects for Theophylline (Theolair); Theobromine; Caffeine
CNS stimulation or seizures, tachycardia/arrythmias, anorexia, nausea
What are the miscellaneous for Theophylline (Theolair); Theobromine; Caffeine
Low therapeutic index! Metabolized by liver; cimetidine and quinoline increase blood levels
What is the class for Roflumilast
Methylxanthine
What is the mechanism for Roflumilast
Selective PDE4 inhibitor; more of an anti-inflammatory agent than bronchodilator
What are the therapeutics for Roflumilast
COPD
What are the important side effects for Roflumilast
CNS stimulation or seizures, tachycardia/arrythmias, anorexia, nausea
What is the class for Ipratropium (Atrovent); Tiotropium; Atropine
Quarternary amine antimuscarinic
