A Gene by Medication Interaction to the Acute Effects of Alcohol

Stopped early · Phase 1 · Has a placebo group

Conditions studied: Alcohol-induced Cue-craving, Alcohol Sensitivity

In brief

Alcohol dependence, or "alcoholism", affects approximately 14 million Americans. Currently, only three pharmacotherapies (disulfiram, naltrexone, and acamprosate) have been approved for the treatment of alcohol dependence and these medications are, at best, moderately successful. Thus, there is a great need for the examination of other biological systems, which contribute/influence the drug reward/addiction pathways within the brain, such that the discovery of new targets and new pharmacotherapies will be possible. Other biological systems in addition to dopamine, such as serotonin, and norepinephrine (NE) are thought to be important in several aspects of addiction, including reward, craving and depression. This study will examine the effects of a 5 day course of atomoxetine (a selective NE transporter (NET) inhibitor) (80 mg/day; Strattera or placebo) on alcohol-elicited craving and sensitivity to alcohol. The novelty of this study is that of atomoxetine and the fact that it targets NET, neither of which has heretofore been examined in the context of alcohol dependence. It is hopeful that this study, of 64 total individuals, will provide the PI with sufficient preliminary data to submit a subsequent R01 application to study atomoxetine and the involvement of specific single nucleotide polymorphisms within the NET gene on alcohol-related phenotypes in alcohol dependent and non-dependent populations. The long-term objective of this research is to develop more efficacious treatment interventions for alcohol abuse and dependence.

Who can join

Age: 21 and older, up to 45. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Males and females age 21 - 45, as verified upon the presentation of a valid, government issued form of ID
• Current DSM-IV diagnosis of alcohol dependence using the Mini International Neuropsychiatric Interview (MINI). Which is a shortened form of the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders or SCID. The MINI will also be used to exclude patients with other diagnoses.
• Participants do not meet DSM-IV criteria for any current (i.e., criteria met at any point in the past 30 days) Axis I disorder (including ADHD treated with medication), other than cocaine dependence or those listed above, that warrants treatment or would preclude safe participation in the protocol
• Not currently take medications that are contraindicated for concurrent use with alcohol;
• No subjects who have trouble reading the English language or visual or hearing problems that may interfere with the collection of data;
• No recurring past history of severe hypertension, glaucoma, hyperthyroidism, circulatory disease, hepatitis, chronic liver disease, ulcer disease, seizure disorder, brain disease, cardiac disease, obstructed bowel, or other current treatment of medical conditions that could determine ineligibility;
• Female subjects must not be breastfeeding and must not be pregnant, as indicated by a pregnancy test that will be conducted immediately prior dispensing of medication.
• Subjects have to have normal EKGs results
• Pulse less than 100 beats per minute
• Participants have to weigh between 125-290; weighing between 125-195 lbs (57 - 88.5 kg)

You may not qualify if…

• Significant medical illness (including severe hypertension) as determined by history and/or complete physical examination. (Note: Presence of mild to moderate chronic diseases not otherwise specifically excluded, that are well controlled by medications/interventions will not be considered clinically significant. However the presence of medical disease that is not well controlled will be considered exclusionary.)
• tachycardia
• seizure disorder
• prior history of myocardial infarction
• Clinically significant cardiovascular disease that precludes safe participation
• hepatic or renal impairment; (ie: liver or kidney enzymes > 3x normal limits)
• pregnant
• currently using MAO inhibitors within 14 days
• narrow angle glaucoma
• currently taking antidepressants or have taken within the last month
• currently taking pressor agents such as:
• Alprenolol
• Carteolol
• Levobunolol
• Mepindolol
• Metipranolol
• Nadolol
• Oxprenolol
• Penbutolol
• Pindolol
• Propranolol
• Sotalol
• Timolol
• Acebutolol
• Atenolol
