Study summary

The study aims to study the effect of gabapentin on the number of alcohol drinking days and heavy drinking days in the Thai clinical alcohol-dependent population by using the double-blinded randomized controlled approach. One-hundred and twelve individuals with alcohol dependence were randomly assigned equally into two groups including treatment with gabapentin and placebo. Thirty-four patients (30.3%) completed the study protocol, i.e. treatment with gabapentin at least 300 mg per day or placebo orally once a day for twelve weeks. Pattern of alcohol drinking were obtained from the timelime followback. Drinking behaviors were compared between the two groups by poisson repeated measures model.

What researchers measure

Primary outcomes

  1. Frequency of heavy drinking

    Days per week of alcohol heavy drinking as measured by timelime followback (TLFB) (Sobell et al., 2001) - adapted Thai version. TLFB is the self-report form for a respondent to note days of heavy alcohol drinking, daily amount, and any symptoms related to alcohol drinking including days per week of alcohol drinking. The TLFB was given to the subjects after explaining how to record daily drinking behaviors and symptoms at home.

    Time frame: weekly for 12 weeks

Secondary outcomes

  1. Frequency of drinking

    Days per week of alcohol drinking as measured by timelime followback (TLFB) (Sobell et al., 2001) - adapted Thai version. TLFB is the self-report form for a respondent to note days of heavy alcohol drinking, daily amount, and any symptoms related to alcohol drinking including days per week of alcohol drinking. The TLFB was given to the subjects after explaining how to record daily drinking behaviors and symptoms at home.

    Time frame: weekly for 12 weeks

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 6, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
