In this lecture from This is Why, Dr. Busti will explain the COPD maintenance inhalers you’ll actually see in practice. In this pharmacology review, we break down LAMA (long-acting muscarinic antagonist) bronchodilators—one of the most important bronchodilator classes for COPD treatment—so you can confidently understand the drugs, the mechanism, and the real-world clinical use.
You’ll learn how to:
- What LAMA / antimuscarinic bronchodilators are and how they work
- Where LAMA inhalers fit in COPD therapy and long-term symptom control
- Key differences and practical pearls for common COPD inhalers
- High-yield side effects, contraindications, and patient counseling points
- How to recognize and avoid common med errors and confusion with inhaler names/classes
Drugs covered:
- Tiotropium (Spiriva)
- Umeclidinium (Incruse Ellipta)
- Aclidinium (Tudorza Pressair)
- Glycopyrrolate (COPD maintenance formulations)
The goal = make medical education easy and clinically relevant.
