Course # 98392 • Herbal Medications: An Evidence-Based Review

Overview

Patients, and in some cases healthcare providers as well, are not fully aware of the health risks incurred by ingestion of herbal medications, either due to their potential adverse effects or pharmacologic interactions with other medications. This situation is further compounded by the fact that at least 60% of the patients taking herbal medications do not disclose this fact to their healthcare provider. This course provides the knowledge and tools required for clinicians to discuss natural health products with patients and other members of the healthcare team. It also discusses the need for physicians and nurses to actively inquire if the patient is taking herbal medications and take this information into account prior to prescribing new medications. A brief historical background and an overview of regulatory bodies responsible for overseeing herbal medications is provided. Relevant examples of widely used herbal compounds are presented. Clinically relevant information on commonly used herbal medications regarding therapeutic effectiveness, pharmacologic mechanism of action, adverse effects and drug interactions are reviewed based on scientific evidence.

Course Objective

Considering the pharmacologic interactions between herbal medications (HMs) and conventional medications, it is paramount to increase the awareness and knowledge of healthcare professionals about HMs. The purpose of this course is to increase healthcare professionals' awareness of the potential risks and benefits of HMs from an evidence-based perspective and promote the planned inclusion of HM use in patients' medical history. This course should allow healthcare professionals to discuss HMs in a knowledgeable and succinct manner with patients and colleagues.

Learning Objectives

Upon completion of this course, you should be able to:

  1. Discuss the prevalent current and historical use of HMs in North America.
  2. Explain the need to inquire about the use of HMs during preparation of a patient's medical history, including components of a culturally sensitive assessment.
  3. Discuss the pharmacology (i.e., pharmacokinetics, pharmacodynamics, drug interactions, adverse drug reactions, toxicology) of HMs.
  4. Describe the differences between the process of development and approval of HMs versus conventional medications, and the implications of health claims and therapeutic efficacy of HMs.
  5. Outline the merits and limitations associated with the application of contemporary scientific principles and methodologies (i.e., evidence-based medicine) to assess the efficacy and safety of HMs.
  6. Discuss, based on scientific and conventional medical principles, the pharmacologic properties, efficacy, safety, toxicology, therapeutic indications, and recommended dosages of saw palmetto and St. John's wort.
  7. Describe the potential risks and benefits of ginkgo.
  8. Identify key characteristics of ginseng.
  9. Discuss the use of echinacea and kava, including potential adverse effects.
  10. Review the use of garlic and valerian as HMs.
  11. Outline the potential medical uses of andrographis and English ivy leaf.
  12. Analyze the available evidence for the use of peppermint, ginger, soy, and chamomile.

He was a Gulbenkian Foundation Scholar and received a Young Investigator Award by the American Brain & Behavior Research Foundation.

Dr. Lança participated in international courses and conferences on neurosciences. He has contributed to a better understanding of the mechanisms underlying the ontogenetic development of the brain opiatergic system. As a research scientist at the Addiction Research Foundation (ARF) in Toronto, he initiated research on the functional role played by dopaminergic cell transplants on alcohol consumption, leading to the publication of the first research reports on cell transplantation and modulation of an addictive behavior. Subsequently, he also investigated the role played by other neurotransmitter systems in the limbic system and mechanisms of reward, co-expression of classical neurotransmitters and neuropeptides and potential role in neuropsychiatric disorders.

He is an Assistant Professor in the Department of Pharmacology at the Faculty of Medicine and at the Faculty of Dentistry at the University of Toronto, where he lectures and directs several undergraduate and postgraduate pharmacology and clinical pharmacology courses. He was the Program Director for Undergraduate Studies in the Department of Pharmacology of the University of Toronto. He has developed clinical pharmacology courses for the Medical Radiation Sciences and Chiropody Programs of The Michener Institute for Health Sciences at the University of Toronto.

Dr. Lança’s commitment to medical education started while a medical student, teaching in the Department of Histology and Embryology, where he became cross-appointed after graduation. In Toronto, he has contributed extensively to curriculum development and teaching of pharmacology to undergraduate, graduate, and medical students.

He has authored research and continuing education in peer-reviewed publications and is the author of six chapters in pharmacology textbooks. Dr. Lança has conducted research in various areas including neuropharmacology, pharmacology of alcoholism and drug addiction, and herbal medications.
