Pharmaceuticals and Nutraceuticals 3.0

for Hearing Loss and (two 90 minute sections)

Tinnitus (Part I and II)

This can be an ABA Tier 1 CEU Program

Abstract

The number of pharmaceuticals available to manage hearing loss and/or tinnitus continues to grow. This program reviews the current pharmaceutical research for hearing loss and tinnitus as well as reviewing the efficacy and safety OTC tinnitus relief products. Patient management strategies are also reviewed. (Word Count: 44)

Statement of the topic

Hearing loss and/or tinnitus can be side effects of over several hundred drugs. Establishing a time line is critical to determine of the patient with hearing loss and/or tinnitus is experiencing an adverse event.

Patients sometimes will not report these side effects to the prescribing physician and may chose to self medicate the problem – especially tinnitus – with over-the-counter products.

Over 80 products are available claiming relief or a cure for tinnitus however none of these products are FDA approved. These herbals/supplements/vibratory devices, laser lights and essential oils are all are available in health food stores and on-line with limited regulation but no FDS approval. Of concern is that only 10% of the combined total number of herbal ingredients/compounds have peer reviewed research. The other 90% of the ingredients have no published research related to tinnitus.

Audiologists need to be aware of these products and their potential harm to some of their patients.

Importance or relevance to attendees

Patient counseling and other management strategies will be presented in order for attendees help their patients make informed decisions about starting or discontinuing an OTC tinnitus relief product.

References are given along with a list of websites for additional information to help manage the tinnitus patient.

SUMMARY

There are many FDA approved pharmaceuticals that have been used to manage hearing loss and/or tinnitus regardless of the etiology of the problem. Several new drugs that are currently undergoing clinical trials are showing promise with certain hearing loss etiologies (i.e., noise induced hearing loss).

Several off-label drugs are also being used for hearing loss/tinnitus management. For example, valium, an antidepressant drug, has been used with limited success with tinnitus patients.

However, the FDA loosely monitors over-the-counter (OTC) nutraceuticals (i.e., vitamin supplements) and classifies nutraceuticals as ‘food.’ This means that efficacy and safety do not have to be demonstrated. The scientific guidelines for evidence-based clinical research do not apply.

Patients who are prescribed pharmaceuticals for tinnitus are under the care of a licensed physician, however, there are some patients can self-medicate with OTC products.

Management strategies differ greatly with pharmaceuticals and nutraceuticals.

There are over 80 products available without prescription for hearing loss and tinnitus. This program reviews several of these product's ingredients that are contraindicated for some patients or could cause other health problems.

This program summarizes the current pharmaceutical research for hearing loss and tinnitus management as well as offering strategies for patients who self-medicate with over-the-counter supplements.

This instructional course is divided into two (2) ninety (90) minute programs:

Part I – Pharmaceutical for Hearing Loss and Tinnitus

Attendees will learn how the U.S. Food and Drug Administration (FDA) closely regulates pharmaceutical clinical trials.

The program continues with an overview of how a drug manufacturer goes from the “proof of concept” phase to the different clinical trial phases before final FDA approval (if approved at all).

Next, a comprehensive review of the drugs that cause hearing loss is presented. The section continues with a comprehensive review of different FDA approved medications used primarily for hearing loss and/or tinnitus as well as several off-label drugs used for the same problem. This section encompasses the biochemistry and pharmacology involved with cochlear hearing loss/tinnitus.

NOTE: Patient management strategies and suggestions for improved communication with the prescribing physician and family pharmacist are summarized at the end of Part II.

Part II – Nutraceuticals for Hearing Loss and Tinnitus

The Dietary Supplement and Health Education Act (DSHEA) of 1994 allows nutraceuticals manufacturers to make statements of their product’s efficacy and safety to influence public opinion without having to back up their claims with evidence-based research.

The Federal Trade Commission (FTC), along with the FDA, share responsibility of efficacy and safety of nutraceuticals however these agencies put the burden of proof on the manufacturer. Using the disclaimer “These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure or prevent any disease” opens the door for opportunity to not only market the product but also give false hope to patients experiencing tinnitus.

Attendees will not only learn which federal and commercial websites provide accurate drug information but also learn about how several of the 80 known over-the-counter (OTC) products that claim tinnitus relief (and in some cases a cure) can be more harmful than helpful with certain patient populations.

The last section of this program will review both pharmaceutical and nutraceutical management strategies which could be helpful to the patient, their family, the prescribing physician and pharmacist.

Suggestions for improved communication between audiologist, patient and primary care physician (or ENT) and pharmacist will be made.

NOTE: The program offers several handouts for future reference. (Word count: 539)
