In this lecture from This is Why, Dr. Busti will break down SABA (Short-Acting Beta Agonist) bronchodilators, like albuterol, for the acute management of asthma symptoms and COPD flare-ups.
You’ll learn how to:
- What SABAs are and when they’re used (rescue vs controller)
- Beta-2 agonist mechanism of action (bronchodilation and smooth muscle effects)
- How fast albuterol works, typical duration, and why it’s “short-acting”
- Core therapeutic uses in asthma and COPD
- How SABAs fit into treatment plans (including “as needed” use)
- Common adverse effects: tachycardia, tremor, palpitations, and more
- Key patient counseling: inhaler technique and when to seek urgent care
Drugs discussed:
- Albuterol (rescue inhaler; MDI and nebulizer)
- Levalbuterol (alternative SABA)
The goal = make medical education easy and clinically relevant.
