Drugs and Dysphagia: Medications Affecting the Gastrointestinal System


This online experience is designed as two separate courses. The first course deals with medications affecting the Central Nervous System. The second course deals with medications affecting the Gastrointestinal System. You may choose to take only one course, or you can take both courses - in any order you wish. Please see the top of this page for information on a discount for registering for both courses. The course material is at a beginning to intermediate level intended for the following professionals: SLP, OT, PT, Clinical Dietitians, Nurses, Pharmacists, and Physician's Assistants.

Both courses contain an identical beginning section reviewing ”Foundational” material consisting of Neuropharmacology, the swallowing process and an overview of the effects of medications on dysphagia. If you take both courses, you have the option of exempting out of the Foundations section the second time by skipping directly to the Midterm Exam. If you achieve an 80% passing score on the Midterm, you may continue with the rest of the course.

There is a required textbook that must be purchased on your own to supplement the course content: Drugs and Dysphagia: How Medications Can Affect Eating and Swallowing by Lynette Carl, Pharm.D., B.C.P.S. and Peter Johnson, Ph.D., CCC-SLP. The book is divided into parts, and the online courses are based on corresponding parts of the book. It is important that the student obtain the text, as examples and test questions will utilize readings from it. Click on the "Associated Media" link above for ordering information.

Following the beginning "Foundations" section, we move on to address medications that can cause dysfunction of the gastrointestinal system and those that are used to treat gastrointestinal dysfunction. This discussion includes medications that:
  • Affect appetite, taste or smell
  • Are used for treatment of pain
  • Cause acute and chronic gastrointestinal injury
  • Are used to treat gastromotility dysfunction
Also discussed are medication induced xerostomia and stomatitis.

Each part of the course describes the mechanism of action of the medications, dosing and side effects, as well as related case studies. Several case study examples are provided, which give you the opportunity to learn how to utilize the text as a quick and easy reference source. This will help you more effectively and consistently reference the textbook when confronted with clinical questions in your healthcare settings. The examples should also provide you with real-life clinical situations that mimic problems confronted in your practice.

COURSE GOAL: The focus of this course is on providing access to precise information valuable in the evaluation and treatment of patients with gastrointestinal system dysfunction and dysphagia.

On completion of this interactive online course, the Learner will be able to:

  • Demonstrate knowledge of the medications most frequently affecting the gastrointestinal system function
  • Discuss the medications associated with altered appetite, taste or smell
  • Discuss medication-induced xerostomia and stomatitis and their affect upon dysphagia
  • Identify medications affecting gastrointestinal motility and explain their effects upon eating and swallowing
  • Identify the major types of medications used for management of pain, and describe how they can impair the ability to eat and swallow
