Week 9- Respiratory Pharmacology Flashcards
Fast Acting Bronchodilators
Classification- Beta 2 Agonist
- works of beta cells in the lungs
- stimulate beta cells which relax smooth muscles in the airways
What are fast acting bronchodilators used to treat?
They are used to treat bronchoconstriction (asthma, COPD, Emphysema)
- Ventolin is most common in pre-hospital
What are the routes for ventolin?
MDI- Metered Dose Inhaler
- Requires a cooperative pt
- Improper technique will result in little to medication entering the body
- Should be used with a spacer to allow for optimal delivery to lungs
Nebulized
- Delivers liquid medications in the form of a fine mist
- Fever is contraindicated
- Need an O2 supply
Long Acting Bronchodilators
- Long acting Beta 2 agonist
- Often have some steroids in them or are used in conjunction with steroids
- Not to be used in emergency situations
- Used to provide control, not relief
What are common long acting puffers?
- Advair
- Symbicort
How do Anticholinergics work?
Works to block the parasympathetic response
- Sympathetic- increases HR and cause bronchodilation
- Parasympathetic- decreases HR and causes bronchoconstriction
How is Anticholinergics commonly given?
- Ipratropium (Atrovent)- given MDI or Nebulized
How does Corticosteroids work?
- Used to reduce bronchial swelling
- Available through inhalation or IV
What are the long term negative effects of Corticosteroids?
- High BS, decreased immune system, generalized edema
What are the common drugs of Corticosteroids?
- Dexamethasone
- Prednisone
- Hydrocortisone
- Betamethasone
What are Diuretics used for?
- Used to help maintain BP and remove fluid from the body
- Beneficial in patients with pulmonary edema
- Most common used in emergency situation is Lasix (Furosemide)
What is the negative side affect of Diuretics?
- Lost of potassium
What do Sympathomimetics
