Interactive Effects of IV Ethanol and IV Nicotine

January 12, 2018 updated by: Yale University

A Laboratory Study on the Interactive Effects of IV Ethanol and IV Nicotine on Subjective Effects and Cognition

There are mixed reports on nicotine's effects on ethanol-induced impairment in cognitive performance and behavior in humans. The main objective of this study is to characterize the interactive effects of acute intravenous (IV) ethanol and nicotine administration on cognition and behavior in healthy smokers. The general hypothesis is that nicotine will attenuate the negative effects of ethanol on cognition and subjective stimulant/sedative effects of ethanol.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years to 50 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Inclusion Criteria:

  1. Male and female;
  2. between the ages of 21 and 50 years;
  3. medically and neurologically healthy on the basis of history, physical examination, EKG, screening laboratories
  4. history of smoking daily for the past 12 months, at least 5 cigarettes daily; not seeking treatment for nicotine dependence
  5. social drinkers no maximum level of alcohol consumption will be defined a priori but individuals who met current DSM -IV criteria for alcohol dependence (abuse will be allowed) will be excluded from the study.

Exclusion Criteria:

  1. history of major medical illnesses that the physician investigator deems as contraindicated for the patient to be in the study;
  2. regular use of psychotropic medication (antidepressants, antipsychotics, or anxiolytics) and recent psychiatric diagnosis and treatment for Axis I disorders including major depression, bipolar affective disorder, schizophrenia or panic disorder;

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Biphasic Alcohol Effects Scale (BAES)
Time Frame: 2 minutes
A 14-item scale with 7 items designed to assess stimulant effects associated with the ascending limb of ethanol intoxication and 7 items developed to measure sedative effects associated with the descending limb of ethanol intoxication.
2 minutes

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Visual Analog Scales of Mood States
Time Frame: 1 minute
The following items will be assessed: high, depressed, anxious, drowsy, irritable, tired, sad, angry, nervous, nauseous, blurred vision, flushed, headache, lightheaded, dizzy, sweating, abdominal discomfort and tingling .
1 minute
QSU-Brief
Time Frame: 2 minutes
A measure of smoking urges reflecting not only intent and desire to smoke, and anticipation of pleasure from smoking, but also anticipation of relief from negative affect and nicotine withdrawal, and urgent and overwhelming desire to smoke.
2 minutes
Digit Symbol Substitution Task
Time Frame: 2 minutes
A test of psychomotor performance, which measures motor persistence, sustained attention, response speed and visuomotor coordination.
