Herbal medicines and interactions with anesthetic agents

Area of Science:

• Pharmacology
• Integrative Medicine
• Patient Safety

Background:

• Herbal medicines are widely used globally and categorized as supplements by the U.S. Food and Drug Administration (FDA).
• The Dietary Supplement Health and Education Act of 1994 lacks stringent requirements for proof of efficacy, safety, and quality control for supplements.
• This regulatory gap leads to unregulated active agent quantities, increasing the risk of adverse effects and drug interactions.

Purpose of the Study:

• To highlight the risks associated with unregulated herbal supplements.
• To emphasize the critical need for physicians to inquire about and educate patients on potential herbal-drug interactions.
• To advocate for scientific clinical trials investigating the anesthetic drug responses to commonly used neutraceutical agents.

Main Methods:

• Literature review and analysis of current regulatory frameworks for herbal supplements.
• Discussion of clinical implications and recommendations for healthcare providers.
• Identification of research gaps concerning the interaction of herbal products with anesthetic drugs.

Main Results:

• Herbal supplements are prevalent but lack rigorous safety and efficacy validation.
• Unregulated active ingredients in supplements pose significant risks for patients, particularly concerning drug interactions.
• The American Society of Anesthesiologists (ASA) recommends discontinuing herbal medications 2-3 weeks before elective surgery.

Conclusions:

• There is a critical need for increased physician awareness and patient education regarding herbal supplement use and potential interactions.
• Scientific clinical trials are essential to understand the effects of common neutraceutical agents on anesthetic drug responses.
• Improved regulation and research are necessary to ensure patient safety with the growing use of herbal products.
