AMERICAN BEVERAGEASSOCIATION Functional Energy Drinks & United States Air Force Gregory Addes Koyama PharmD. Candidate, 2014 University of Pacific Thomas J. Long School of Pharmacy
Major Problem Plaguing the USAF 1Wheeler, 2002 2Miller, 2007 FATIGUE Fatigue was a causal or contributing factor in 12.7% of Class A aircraft mishaps No single factor ranked more detrimentalto performance and safety than FATIGUE1 USAF Fatigue Counter-Measures2: Non-Pharmacological agents Pharmacological agents
Dextroamphetamine & the USAF The Pros Dextroamphetamine is the most widely studied and extensively utilized pharmacologic fatigue countermeasure. Its use by military forces dates back to World War II3 The US Air Force formally authorized dextroamphetamine more than 40 ago3 Not a single event of pilot disqualification occurred due to inappropriate use or abuse3 The Cons • Drug Class: C-II • Black Box Warning: “High Abuse Potential” • Adverse Drug Reactions: • MI/Stroke • HTN • Seizures • 3Cornum, 1997
Caffeine & the USAF • 4Gillingham, 2004 • 5Tikiuisus, 2004 • 6Tharion, 2003 • 7McLellan, 2005 • 8Van Dongen, 2001 USAF Caffeine Studies: • Sustain Vigilance & Reaction Time • Caffeine improved both in fatigued subjects under military conditions4,5 • Improve MARKSMANSHIP • Sleep debt and Circadian Variationhas shown to reduce accuracy6,7 • Reduce SLEEP INERTIA8
Caffeine & the USAF 1Wheeler, 2002 Current Use of Caffeine: • Coffee & Soft Drinks1 • Jolt Cola • Mountain Dew • Caffeinated Gum1 • Included in Meals Ready to Eat (MREs)
Everything you ever wanted to know about Energy Drinks in 3 minutes
What’s in a “Energy Drink”? Caffeine L-Carnitine Guarana Extract Taurine
CAFFEINE • Is it Safe? • The FDA thinks so: • Caffeine is considered safe for use in stimulant drug products for over-the-counter human use to restore mental alertness or wakefulness during fatigue or drowsiness9 • How Much is Safe? • The FDA recognizes that for healthy adults, caffeine intake up to 400 mg/day is safe10
L-Carnitine • What is L-Carnitine? • Quaternary Ammonium compound • Biological Role: Transport of fatty acids to mitochondria for generation of metabolic energy11 • Where is it Commonly Found? • Ground Beef (100g) • 94mg of L-Carnitine • Whole Milk (100mL) • 3.3mg
L-Carnitine • Is it Safe? • The European Food Safety Authority (EFSA) found no adverse effects attributable to the consumption of L-carnitine at doses less than or equal to12: 2 grams/day
Guarana Extract • What is Guarana? • “Vine plant” native to the Amazon Basin • Historically played an important role in the Tupi & Guarani Paraguayan culture13 • Use to make Tisane—or “Guarana Bread”
Guarana Extract • Is Guarana Safe? • FDA-approved food additive (21 CFR 172.510) • Generally Recognized As Safe(GRAS) for use as a flavoring agent14 • Does GuaranaContribute to Caffeine Content? • Guarana in an 8ozserving of Rockstar= <1mg of caffeine14
TAURINE • What is Taurine? • Occurs naturally in the diet • Considered a “ConditionallyESSENTIAL”Amino Acid14 • Found in Breast Milk & Infant Formula15,16
TAURINE • Is it Safe? • Taurine does NOT have any stimulatory effects17 • The European Food Safety Authority (EFSA) found no association between Taurine & any adverse health effects17 • 3 g to 6 g of Taurine per day for up to 1 year did NOT produce adverse health effects17
Are Functional Energy Drinks DANGEROUS? YES GI disturbances Cardiovascular Risks Combination with Alcohol The WORLD is a Dangerous Place… But so is the life of USAF Personnel
USAF Dominance 19Meadows, 2005 A tremendous advantage held by the US military is the capacity to conduct operations on an around-the-clock basis19
Threat to Mission Success The Threat In carrying out these operations, our own military forces become sleep deprived, and the problem presented by fatigue may become immense1 The Need Effective maintenance of the Human Weapon System is critical to mission success1
Furthering the Mission of the USAF The Solution ENERGY DRINKS • Limited Role of Dextroamphetamine • Can only be prescribed by the flight surgeon to Aviators in the USAF2 • Energy drinks are available Over-The-Counterand have shown to be both SAFE & EFFECTIVE
PERSPECTIVE • Guns & Energy Drinks • Aurora Shooting • History of mental illness & suicide attempts • “14 year old Dies from Energy Drink Consumption” • TWO 24-oz Monster Energy Drinks • History of Cardiovascular Abnormalities • Risk vs. Benefit

Energy Drinks: Safety and Efficacy Issues Daniel Da Costa PharmD Candidate 2014 University of the Pacific Thomas J. Long School of Pharmacy and Health Sciences
Why Discuss Energy Drinks? • From 2008-2012 the US Energy Drink Market grew by 60% • Sales of more than $12.5 billion in 2012 • Energy Drink related ER visits doubled over a 4 year span • Deaths due to Energy Drink consumption (without use with other substances) • In 2010 products containing Energy Drinks mixed with alcohol were pulled of the market due to deaths related to use • United States Senate Hearing: Energy Drinks: Exploring Concerns about Marketing to Youth
What are Energy Drinks? • Refers to a class of products that contain high levels of caffeine frequently combined with other stimulants and ingredients in liquid form for consumption. • Fall into one of two categories: • Beverage • Dietary Supplements • FDA Draft Guidance for Industry: 2009 • Increase in the marketing of beverages as dietary supplements, in spite of the fact that the packaging and labeling of many liquid products represent the products as conventional foods • Concern with dietary supplements that look like, are displayed adjacent to, and are marketed, as beverages.
Efficacy of Energy Drinks DAWN Report: Marketing suggests benefits such as increased energy and stamina, weight loss, and enhanced physical and mental performance http://www.orangeinks.com/wp-content/uploads/2013/03/Monster-Hulk.jpg • Increased Energy and Stamina: • Improved cycling time-trial performance after ingestion of a caffeine energy drink. • Ivy, JL. 2009 • Weight Loss: • Thermogenic effect of Meltdown RTD energy drink in young healthy women: a double blind, cross-over design study. • Rashti, SL. 2009 • Enhanced Physical and Mental Performance: • Positive effects of Red Bull® Energy Drink on driving performance during prolonged driving- • Mets, MA. 2011

What Makes Energy Drinks Effective? Caffeine is the most common ingredient in Energy Drinks Caffeine has shown to have stimulatory effects, increasing performance, vigilance, alertness, memory and mood • Caffeine is the most widely consumed psychoactive substance in the world • 80% of American adults consume caffeine every day • 300mgis the average daily intake of caffeine of Americans http://learning.hccs.edu/faculty/steven.dessens/steven.dessens/website_pictures/caffeine
Typical Energy Drink Content • Wide range of Caffeine Content: • 6mg- Decaf 5 Hour Energy • 375mg- Rage Inferno • Photo from AngryTrainerFitness.com
Safety of Energy Drinks • GRAS- Generally Regarded as Safe • Chemical or substance added to food considered safe by experts • Caffeine is regarded by the FDA as GRAS at “cola-type” levels of 71mg/12 ounces • Select Committee on GRAS Substances (SCOGS) Review Database • U.S. Food and Drug Administration Conclusion • “It is inappropriate to include caffeine among the substances generally recognized as safe (GRAS). At current levels of consumption of cola-type beverages, the dose of caffeine can approximate that known to induce such pharmacological effects as central nervous system stimulation.”
Other Ingredients- GRAS? • Guarana • Taurine • L-Carnitine • B Vitamins • ED companies self determine many of these ingredients to be safe. • Independent consulting firms have reported these additives as GRAS, but this is not the opinion of the FDA
Safe Dose of Caffeine? • FDA- 400mg daily is not associated with significant adverse effects in healthy adults • Some side effects: • GI upset • Jitteriness • Difficulty sleeping • Cardiovascular
Caffeine Dosing Evaluation of electrocardiographic and hemodynamic effects of caffeine with acute dosing in healthy volunteers Methods: 400mg caffeine vs placebo Conclusions: Moderate caffeine consumption by healthy young adults does not acutely effect PR, QRS, QT, QTc and RR intervals However, caffeine did increase SBP in placebo vs caffeine : 119 + 7 mmHg 128+ 8mmHg -Ammar, 2001
Energy Drink Safety • Impact of Energy Drinks on Electrocardiographic and Blood Pressure Parameters: A meta-analysis of Clinical Studies • Methods: Meta-analysis of three studies evaluating the impact of an energy drink on the QT/QTc interval, SBP, DBP and HR. • 132 subjects in BP analysis • 93 subjects in QT/QTc analysis • Conclusions: Energy drinks raised blood pressure significantly prolonged the QT/QTc interval. • SBP Increase: 3.5mmHg • Torcetrapib stopped in clinical trials in part due to an SBP increase of 6.6 mmHg • QTc Prolongation: 10msec • FDA Guidance Document calls for further analysis of QTc prolonging medications if the interval prolongs for more than 10msec, warranting further investigation • -Dargush, 2012
Safety • Center for Food Safety and Applied Nutrition Adverse Event Reporting System (CAERS) • 5 Deaths- Monster Energy Drink • 13 Deaths- 5 Hour Energy • Adverse Events • Seizures • Dysrhythmias
Safety • DAWN Report: The number of emergency department visits involving energy drinks doubled from 10,068visits in 2007 to 20,783visits in 2011 • Over 52% of ER visits made by people aged 18-25 involved combinations of energy drinks with alcohol or other drugs. • National Academy of Sciences Report (2012): nearly half (47%) of military members surveyed reported binge drinking (consuming 5 or more drinks at one time)
Safety Increasing ER Visits Mixture with Alcohol High Dose Caffeine Combination of Ingredients
Energy Drinks • Increase in consumption of Energy Drinks • Increase in Emergency Room visits and deaths • Benefits of Energy Drinks • Caffeine is an effective substance within certain doses • Energy Drinks have adverse effects • Lack of data regarding combination of other ingredients in Energy Drinks
