- Brief Summary
The purpose of the study is to assess the relevance of gender in the acute effects (subjective, physiological and driving-related skills) observed after controlled administration of alcohol in a binge-drinking pattern mixed with energy drinks (AmED)
- Detailed Description
Consumption of alcohol mixed with energy drinks (AmED) has increased mainly among young people. Energy drinks (ED) are usually combined with alcohol with the intention of counteracting its effects. However, most studies have not shown a reduction in drunkenness and consumption is related with engagement of risk-taking behaviours like driving under alcohol effects. It is already known that alcohol concentrations and effects are higher in women than in men even after adjusting dose by weight.
The relevance of gender in the acute effects of alcohol associated with ED consumed in a binge-drinking pattern has been poorly studied. A randomized clinical trial will be conducted in healthy volunteers (1:1) and four treatment conditions will be administered: alcohol+ED, alcohol+placebo of ED, placebo of alcohol+ED and placebo of alcohol+placebo of ED. Subjective and physiological effects, driving related skills, and alcohol and caffeine concentrations will be measured along an 8-hours period. A pilot study has been conducted with the first 6 volunteers to select the alcohol doses. In the definitive study 70 g of alcohol in men and 55 g in women will be used.
Recruitment & Eligibility
- Status
- UNKNOWN
- Sex
- All
- Target Recruitment
- 32
- Males and females between 18-40 years old, weight between 50 and 100 kg and BMI (BMI=weight/height²) between 20-28 kg/m². Lower or higher BMIs will be allowed, if the researchers considered that do not suppose a risk to the subjects and do not interfere with the objectives of the study.
- Recreational alcohol consumption in form of occasional binge-drinking (≥1 episode / month) and at least consumption of 1 unit (10 g, "standard" drink - one alcoholic drink equivalent) per day or its equivalent over the whole week [7 units, 70 g)]) and having experienced drunkenness several times
- Regular consumption of beverages containing methylxanthines at least 7 per week (coffee, tea, chocolate, cola soda, energy drinks). Consumption of energy drinks at least once.
- Understand and accept the study's procedures and sign an informed consent form.
- No evidence of somatic or psychiatric disorders as per past medical history and physical examination.
- The ECG and general blood and urine laboratory tests performed before the study should be within normal ranges. Minor or occasional changes from normal ranges are accepted if, in the investigator's opinion, considering the current state of the art, they are not clinically significant, are not life-threatening for the subjects and do not interfere with the product assessment. These changes and their non-relevance will be justified in writing specifically.
- Not fill the inclusion criteria.
- Pathological history or evidence of a preexisting condition (including gastrointestinal, liver, or kidney disorders) that may alter the absorption, distribution, metabolism or excretion of drugs or symptoms suggestive of drug-induced gastrointestinal irritation.
- Present history of a substance use disorder according to Diagnostic and Statistical Manual for Mental Disorders (DSM-V), except for nicotine. Past history of mild substance use disorder (corresponding to substance abuse according to DSM-IV) could be included.
- Previous or actual psychiatric disorders, alcoholism, abuse of prescription drugs or illegal substances or regular consumption of psychoactive drugs.
- Having donated blood or having participated in this same study in the preceding 8 weeks, or having participated in any clinical trial with drugs in the preceding 12 weeks
- Having had any somatic disease or having undergone major surgery in the 3 months prior to inclusion in the trial.
- Individuals intolerant or having experienced a severe adverse reaction to alcohol or energy drinks. Asian subjects with no intolerance or no serious adverse reactions to alcohol could be included.
- Having regularly taken medication in the month before the trial, except for vitamins, herb-based remedies, dietary supplements that if, according to the Principal Investigator or his appointed collaborators' opinion, they pose no threat to the subjects and they won't interfere with the study's objectives. Single doses of symptomatic drugs taken during the week before the experimental session will not constitute an exclusion criterion if it can be assumed that it has been completely eliminated on the day of the experimental session.
- Smokers of >5 cigarettes/day
- Consumption of >20 g/day of alcohol (females) or of >40 g/day (males)
- Daily consumption of more than 5 coffees, teas, cola drinks or other stimulant or xanthine-containing beverages in the 3 months prior to inclusion in the study.
- Subjects unable to understand the nature, consequences of the study and the procedures requested to be followed.
- Subjects with positive serology to Hepatitis B, C or HIV.
- Pregnant, breastfeeding women and those using hormonal contraception,. Those not using an effective contraceptive (i.e. abstinence, intrauterine devices, barrier methods or partner vasectomy).
- Women with amenorrhea or suffering severe premenstrual syndrome.
