Isoproteronol
Beta1/2 selective
- B1: tachycardia
- B2: relaxes bronchial smooth muscle
Albuterol
Short acting beta-2 agonist
Salmeterol
Long acting beta-2 agonist
Theophylline
Mediates bronchodilation/inhibits bronchoconstriction by inhibiting PDE, increasing life of cAMP (activated with beta-agonists)
Ipratropium
Competitive inhibition of muscarinic receptors (M3 mediates bronchoconstriction), prevents bronchoconstriction
Cromolyn
Prevents mast cell mediator release
- Asthma ppx only, not for acute attack
Beclomethasone
Corticosteroid
- Inhibit synthesis of virtually all cytokines, inactivates NF-kappaBeta (TF that induces production of TNF-alpha, which is normally produced by macrophages for leukocyte recruitment)
- First line for chronic asthma
SEs: oropharyngeal candidiasis, dysphonia (laryngeal myopathy), incr IOP, cataracts, decr growth, bone loss, decr HPA axis
Prednisone
Corticosteroid
- Inhibit synthesis of virtually all cytokines, inactivates NF-kappaBeta (TF that induces production of TNF-alpha, which is normally produced by macrophages for leukocyte recruitment)
- First line for chronic asthma
SEs: oropharyngeal candidiasis, dysphonia (laryngeal myopathy), incr IOP, cataracts, decr growth, bone loss, decr HPA axis
Zileuton
Anti-leukotriene, asthma prevention
- 5-lipooxygenase pathway inhibitor (AA –> leukotrienes)
Zafirlukast
Anti-leukotriene, asthma prevention
- Blocks leukotriene receptor
SEs: incr LFTs, HA, eosinophilic vasculitis
Montelukast
Anti-leukotriene, asthma prevention
- Blocks leukotriene receptor
SEs: incr LFTs, HA, eosinophilic vasculitis
Guaifensin
Expectorant
- Removed excess sputum, does NO suppress cough reflex
N-acetylcysteine
Expectorant
- Can loosen mucous plugs in CF pt
- Acetominophen OD: binds toxic acetominophen metabolites to prevent glutathione depletion
Bosentan
Endothelin receptor antagonist,
- Blocks endothelin-1 receptors, decreases pulm vascular resistance
Sitaxentan
Endothelin receptor antagonist,
- Blocks endothelin-1 receptors, decreases pulm vascular resistance
Ambrisentan
Endothelin receptor antagonist,
- Blocks endothelin-1 receptors, decreases pulm vascular resistance
Dextromethorphan
Antitussive
- Antagonizes NMDA glutamate receptors
- Synthetic codeine analog (opioid)
Naloxone for OD
Pseudoephedrine
Sympathomimetic alpha-agonist (vascular smooth muscle contraction, pupil dilation, GI/bladder sphincter contration)
- Nasal decongestant
- SE: HTN, anxiety (CNS stimulant)
Phenylephrine
Sympathomimetic alpha-agonist (vascular smooth muscle contraction, pupil dilation, GI/bladder sphincter contration)
- SE: HTN
Methacholine
Muscarinic receptor agonist (bronchoconstriction)
- Asthma challenge test
