Module 4: Body Systems: Respiratory

Introduction 

This module reviews the anatomy and physiology of the upper and lower respiratory systems and explores drugs used to treat conditions that affect breathing. You will learn about various respiratory diseases, including asthma, chronic obstructive pulmonary disease, allergies, cough and colds, and the drugs used to treat them. You will examine the mechanism of action, physiological effects, and side effects of major drug classes. Understanding the connection between respiratory anatomy and physiology and specific pharmacological interventions is key in a clinical setting where respiratory conditions are frequently encountered.

Learning Objectives 

1. Recall the major classes of drugs used to treat asthma, COPD, allergies, common colds, and respiratory infections. 
2. Explain the mechanisms of action for beta-2 agonists, inhaled corticosteroids, and antibiotics used in respiratory disorders. 
3. Apply knowledge of drug classes to match appropriate pharmacologic therapy to specific respiratory conditions in patient scenarios. 
4. Analyze the rationale for choosing certain medications (e.g., corticosteroids vs. leukotriene inhibitors) based on case histories, symptoms, and contraindications. 
5. Evaluate a patient’s medication regimen for effectiveness, possible adverse effects, and drug interactions, and propose evidence-based interventions or modifications if needed. 

To achieve these objectives:

1. Read the Module 4 Introduction 
2. Read Chapter 6. Respiratory Pharmacology in Introduction to Pharmacology - aligns with computer proficiency 
3. Complete the Module 4 Discussion Form - aligns with computer proficiency, internet navigation, digital communication, and collaboration
