Unit 8: Gastrointestinal Pharmacology

Gastrointestinal Pharmacology

Gastrointestinal Pharmacology

Welcome to Unit 8 of Advanced Pharmacology

There are a wide variety of drugs used to treat gastrointestinal disorders. Several groups of drugs are used almost exclusively to treat GI conditions. Our focus will be primary care thus intravenous formulations will not be discussed. Clinical use and dosing of drugs will be the focus as with other units and include an emphasis on rational drug selection and patient education.

Primary care providers also see a variety of GI disorders, including gastroesophageal reflux disease and peptic ulcer disease. Over the past several years, over-the-counter medications have become available to treat these conditions. However, it is important to understand the underlying pathophysiology, and know when over-the-counter treatment is ineffective. Stepwise approaches to care and special population considerations will be discussed.

Unit Learning Objectives

Examine the principles of pathophysiology and therapeutics that direct the pharmacotherapeutic interventions affecting the gastrointestinal system (CLO 1)

Analyze the pharmacokinetic and pharmacodynamic actions of agents affecting the gastrointestinal system (CLO 2)

Apply critical-thinking processes to the management and evaluation of expected effects, potential adverse effects, and potential interactions of pharmacological agents affecting the gastrointestinal system (CLO 1,2)

Apply the evidence for pharmacotherapeutic interventions in a patient with gastrointestinal system disorders (CLO 1,2,3)

Evaluate the impact of pharmacogenomics, access, cost, quality, and safety on prescribing for Drugs Affecting the Gastrointestinal System (CLO 4)

Unit Conclusion

Unit Conclusion

As we wrap up unit 8 of Advanced Pharmacology, we discussed the wide variety of drugs used to treat gastrointestinal disorders. We also learned in-depth treatment of GI disorders. Stepwise approaches to care and special population considerations are always important to remember when prescribing medications. Recall that rational drug selection emphasizes concentrating on resolving or treating the underlying disease state while reducing side effects.
