About this study

OBJECTIVES: I. Determine whether the benzodiazepine alprazolam reinforces self-medication behavior in anxious patients with varying histories of using other drugs.

II. Establish outpatient methods for the study of self-medication and drug reinforcement in patients vulnerable to prescription drug abuse or dependence.

III. Evaluate the influence of alcohol and other non-prescription drug use as determinants of vulnerability in these patients.

IV. Identify personality, attitudinal, or other variables that might predict different patterns of self-medication.

  1. Assess the effects of cognitive-behavioral therapy on alprazolam self-medication.
Read the detailed description

PROTOCOL OUTLINE: This protocol involves different experiments examining self-medication with anxiolytic medications in selected patients, and cognitive-behavioral therapy for anxiety. Capsules are color coded and taken under double-blind conditions. Compliance is monitored with the Medication Event Monitoring System, which automatically registers the date and time each bottle is opened.

The physician directs therapy administration, using some combination of the following: blind choice test, antianxiety agent(s), placebo, and cognitive-behavioral therapy.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing alprazolam in people with Anxiety Disorder and Panic Disorder, run by National Institute on Drug Abuse (NIDA) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jun 2005. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00004373, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2005.
