Effects of energy drink ingestion on alcohol intoxication.Ferreira SE, de Mello MT, Pompeia S, de Souza-Formigoni ML.

BACKGROUND: Well-known reports suggest that the use of energy drinks might reduce the intensity of the depressant effects of alcohol. However, there is little scientific evidence to support this hypothesis. OBJECTIVE AND METHODS: The present study aimed at evaluating the effects of the simultaneous ingestion of an alcohol (vodka(37.5%v/v)) and an energy drink (Red Bull-3.57 mL/kg), compared with those presented after the ingestion of an alcohol or an energy drink alone. Twenty-six young healthy volunteers were randomly assigned to 2 groups that received 0.6 or 1.0 g/kg alcohol, respectively. They all completed 3 experimental sessions in random order, 7 days apart: alcohol alone, energy drink alone, or alcohol plus energy drink. We evaluated the volunteers' breath alcohol concentration, subjective sensations of intoxication, objective effects on their motor coordination, and visual reaction time. RESULTS: When compared with the ingestion of alcohol alone, the ingestion of alcohol plus energy drink significantly reduced subjects' perception of headache, weakness, dry mouth, and impairment of motor coordination. However, the ingestion of the energy drink did not significantly reduce the deficits caused by alcohol on objective motor coordination and visual reaction time. The ingestion of the energy drink did not alter the breath alcohol concentration in either group. CONCLUSIONS: Even though the subjective perceptions of some symptoms of alcohol intoxication were less intense after the combined ingestion of the alcohol plus energy drink, these effects were not detected in objective measures of motor coordination and visual reaction time, as well as on the breath alcohol concentration.

Can energy drinks reduce the depressor effect of ethanol? An experimental study in mice.Ferreira SE, Hartmann Quadros IM, Trindade AA, Takahashi S, Koyama RG, Souza-Formigoni ML.

Although the popularization of the combined use of alcoholic beverages and energy drinks (ED) containing caffeine, taurine and other substances has increased, there are no controlled experimental studies on the effects of ED alone or combined with ethanol. This work aimed at evaluating the effects of different doses of ED combined or not with ethanol, on the locomotor activity of Swiss mice. The administration of 3.57, 10.71 or 17.86 ml/kg of ED alone increased the locomotor activity of the animals in relation to a control group. Low doses of ethanol (0.5, 1.0 and 1.5 g/kg) alone or in combination with 10.71 ml/kg of ED did not affect their locomotor activity. However, the reduction of activity observed after 2.5 g/kg of ethanol was antagonized by 10.71 ml/kg of ED. Further studies on the mechanisms of this interaction are still needed.

Does an energy drink modify the effects of alcohol in a maximal effort test?Ferreira SE, de Mello MT, Rossi MV, Souza-Formigoni ML.
Department of Psychobiology, Federal University of Sao Paulo (UNIFESP), Sao Paulo Brazil.

BACKGROUND: There are popular reports on the combined use of alcohol and energy drinks (such as Red Bull and similar beverages, which contain caffeine, taurine, carbohydrates, etc.) to reduce the depressant effects of alcohol on central nervous system, but no controlled studies have been performed. The main purpose of this study was to verify the effects of alcohol, and alcohol combined with energy drink, on the performance of volunteers in a maximal effort test (cycle ergometer) and also on physiological indicators (oxygen uptake, ventilatory threshold, respiratory exchange rate, heart rate, and blood pressure), biochemical variables (glucose, lactate, insulin, cortisol, ACTH, dopamine, noradrenaline, and adrenaline), and blood alcohol levels. METHODS: Fourteen healthy subjects completed a double-blind protocol made up of four sessions: control (water), alcohol (1.0 g/kg), energy drink (3.57 ml/kg Red Bull), and alcohol + energy drink, each 1 week apart. The effort test began 60 min after drug or control ingestion, and the dependent variables were measured until 60 min after the test. RESULTS: Heart rate at the ventilatory threshold was higher in the alcohol and alcohol + energy drink sessions in comparison with control and energy drink sessions. Although in comparison to the control session, the peak oxygen uptake was 5.0% smaller after alcohol ingestion, 1.4% smaller after energy drink, and 2.7% smaller after the combined ingestion, no significant differences were detected. Lactate levels (30 min after drug ingestion, 30 and 60 min after the effort test) and noradrenaline levels (30 min after the effort test) were higher in the alcohol and alcohol + energy drink sessions compared with the control session. CONCLUSIONS: The performance in the maximal effort test observed after alcohol + energy drink ingestion was similar to that observed after alcohol only. No significant differences between alcohol and alcohol + energy drink were detected in the physiological and biochemical parameters analyzed. Our findings suggest that energy drinks, at least in the tested doses, did not improve performance or reduce alterations induced by acute alcohol ingestion.

Alcohol and energy drink--can combined consumption of both beverages modify automobile driving fitness?][Article in German]
Riesselmann B, Rosenbaum F, Schneider V.
Landesinstitut fur gerichtliche und soziale Medizin Berlin.

Various fitness drinks under the designation of "energy or power drinks" or "brain or athletic food" are very popular among young people. For those entrusted with rendering expert opinions that poses the question of whether consumption of these beverages is of any importance when a person's ability to drive or mental capacity has to be assessed, especially in combination with alcoholic beverages imbibed at the same time. In the case discussed here-both the 20-year-old car driver and his passenger suffered not inconsiderable injuries-an alcohol concentration of 1.2 per mille was found at the time a blood sample was taken. Furthermore, a caffeine content of 1.5 micrograms/ml was noted. A value also reached after drinking a cup of filter coffee. In contrast, values of 2 to 10 micrograms/ml are reached when caffeine is used for therapeutic purposes. Values of more than 15 micrograms/ml are considered toxic. The measured caffeine content was thus fully insignificant. The same also applies to the "active ingredients" (taurine, glucuronolactone) contained in the beverage "Red Bull". Another assumption that, namely, the effect of alcohol can be offset by such beverages could lead to a situation in which young people incorrectly assess their ability to drive after imbibing alcohol and fitness drinks. That is naturally given support by corresponding tributes by the manufacturers ("improves performance", "invigorates the mind and body").
