About this study

Official title: Effects of Buspirone in Withdrawal From Opiates

Dependence on heroin is a major public health problem because of its association with criminality, law enforcement costs and healthcare costs. Managed withdrawal is a required first step for a long term drug-free treatment of heroin addicts. Methadone and clonidine have been the mainstay of treatment for the relief of heroin withdrawal symptoms but both have limitations. The purpose of this study was to evaluate the efficacy of buspirone in the alleviation of the withdrawal symptoms experienced by heroin addicts when they stop using heroin. Buspirone is a non opiate drug with no abuse potential, no sedating effects and no withdrawal symptoms.

Read the detailed description

In an attempt to develop a new opiate detoxification approach, the authors assessed the efficacy of buspirone in the treatment of acute heroin withdrawal. Buspirone, a drug interacting with the serotonergic system was selected because there is evidence that a decrease in serotonergic neurotransmission may be involved in opiate withdrawal symptomatology.

Hospitalized heroin addicts were randomized to 4 groups: 1) placebo; 2) methadone; 3) buspirone 30 mg daily; 4) buspirone 45 mg daily. The double-blind trial started in all patients with a 5-day methadone stabilization period ending with a 30 mg dose. This was followed from day 6 through 12 by placebo in group 1 and by a methadone taper in group 2. Because of its delayed action, buspirone was started on day 1 in groups 3 and 4 and was continued, after methadone discontinuation, through day 12. On day 13, drugs and placebo were discontinued and patients observed through day 14. Withdrawal symptoms were assessed with the "Subjective Opiate Withdrawal Scale" (SOWS) and the "Objective Opiate Withdrawal Scale" (OOWS). Participants met with a research assistant daily for 30 minutes while on an inpatient unit. The study did not interfere with the scheduled ward activities. Results so far indicate that the SOWS and OOWS scores were significantly higher in the Placebo group than in the Methadone, Buspirone 30 mg and Buspirone 45 mg groups. There were no significant differences in SOWS or OOWS scores when the Methadone group was compared to each of the two Buspirone groups or when the two Buspirone groups were compared to one another. Thus buspirone, a non opiate drug with no abuse potential, a safe side effect profile and no withdrawal symptoms at doses of 30 and 45 mg, was as effective as a methadone taper in alleviating the withdrawal symptoms of heroin addicts stabilized for 5 days with, and then withdrawn from, methadone. Additional analyses will be performed using data collected in the course of the study.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Buspirone in people with Heroin Dependence, 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?

The sponsor lists 5 inclusion and 3 exclusion criteria. 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 12 Jan 2017. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 NCT00326235, which also lists 1 linked publication.

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 12 Jan 2017.
