Pharmacology Flashcards
What are the 4 administration techniques for asthma medications?
MDI (meter dose inhaler) Nebulizer (liquid med in machine) Inhaled powder (rotacaps, disc-inhaler) Systemic admin (ora or parenteral routes IV, IM, SQ)
Albuterol, Proventil, Ventolin Class MOA Onset/duration Route
Class: SABA
MOA: bronchodilator
Onset: 15 min before activity or for acute attacks
Duration: 4-6 hours
Route: inhalation (can do IV but no advantages)
How do the sympathomimetics bronchodilators (beta-2 agonists) work?
- produce airway dilation
- vasodilation of smooth muscle in lungs!!!
- improve mucocilliary transport
- stimulate beta-andrenergic receptors
What are the SABA used for?
- prevention of exercise induced bronchospasm (asthma)
- help with ACUTE attacks
- inhibit smooth muscle contraction
What are the LABA used for?
Maintenance medication
inhibit smooth muscle contraction
NOT for acute attacks
Do NOT use alone, need to use with ICS
Levalbuterol (Xopenex) Class MOA Onset/duration Route
class: SABA MOA: bronchodilator --inhibit smooth muscle contraction Onset: less than 5 min Duration 6-8 hours Route: nebulizer
Salmeterol (Serevent) Class MOA Onset/duration Route Uses
Class: LABA MOA: bronchodilator --inhibit smooth muscle contraction Onset: 20 min Duration: 12 hours Route: diskus Uses: asthma/bronchospasm
Formoterol (Foradil) Class MOA Onset/duration Route Uses
Class: LABA MOA: bronchodilator--inhibit smooth muscle contraction Onset: 20-30 min Duration: 12 hours Route: inhaler Uses: asthma
Ipratropium (Atrovent) Class MOA Onset/duration Route Uses
Class: anticholinergic MOA: anticholinergic, reverses acetylcholine-induced bronchospasm (inhibiting parasympathetic nervous system) --inhibit smooth muscle contraction Onset: ? Duration: Q6 Route: inhaler Uses:bronchospasm for COPD
Parasympathetic vs. sympathetic in asthma. What does what and what are you inhibiting/stimulating?
Parasymphathetic = constricts the airway, so want to inhibit acetylcholine
Sympathetic = opens the airways, so you want to stimulate the beta-2 receptors
So: either can stimulate sympathetic and or inhibit the parasympathetic
Tiotropium (Spiriva) Class MOA Onset/duration Route Uses
Class: anticholinergic MOA: reverses acetylcholine induced bronchospasm (parasymp)--inhibit smooth muscle contraction Onset: ? Duration: 24 hours Route: diskus Uses: bronchospasm w/ COPD
Theophylline (Theo-Dur) Class MOA Route Uses Monitoring
Class: methylxanthine
MOA: prevents and/or reverse inflammation
Route: liquids, tablets, capsules
Uses: maintenance therapy -moderate–severe asthma, COPD
Monitoring: small TI, blood draws, can be toxic
