Jan 27, 2026
Anthony Busti, MD, PharmD, MSc, FNLA, FAHA

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.
