Study Notes
Asthma vs. COPD
- Asthma and COPD are major global health concerns
- Both are characterized by airway obstruction
- Asthma is characterized by episodic airway obstruction with variable airflow limitation
- Asthma can be associated with airway inflammation and structural changes
- COPD is characterized by progressively worsening airflow limitation
- COPD may present with shortness of breath and dyspnea, even with high doses of control meds
Asthma
- Respond well to inhaled corticosteroids and other controllers with a red or brown color code
- Respond well to relievers with a blue color code
- For poorly controlled asthma patients, add-on therapies may be necessary, including
- Long-acting antimuscarinic agent (LAMA)
- Leukotriene receptor antagonists (LTRA)
- Targeted (monoclonal antibody) therapy
COPD
- For poorly-controlled COPD patients, add-on therapies may be necessary, including
- Long-acting antimuscarinic agent (LAMA)
- Leukotriene receptor antagonists (LTRA)
- Targeted (monoclonal antibody) therapy
β2-agonists Adverser Effects
- β2-agonists are used to treat asthma and COPD
- β2-agonists work by stimulating β2-receptors in the lungs
- Some common adverse events of β2-agonists include:
- Tremors - due to stimulation of β2-receptors in skeletal muscles
- Vasodilation - due to β2-receptor stimulation
Characteristics of Long Acting β2-Agonists (LABA)
- LABAs are used to treat both Asthma and COPD
- LABAs are lipophilic and have a long duration of action
- Some common LABAs include:
- Salmeterol - has a duration of action of 12 hours and is typically given twice a day
- Formoterol - has a duration of action of 12 hours and is typically given twice a day
- Olodaterol - has a duration of action of 24 hours and is typically given once a day
- Villanterol - has a duration of action of 24 hours and is typically given once a day
- Indacaterol - has a duration of action of 24 hours and is typically given once a day
- Indacaterol has the longest half-life of all the LABAs
- Olodaterol, Villanterol, and Indacaterol are typically given once a day due to their 24 hour duration of action
Respiratory Deposition Model
- The respiratory deposition model helps to understand how inhaled medications reach their target in the lungs
