Clinical Study of Ligustrazine in Treating Alcohol Addiction
Study Details
Study Description
Brief Summary
Alcohol consumption is one of the most important risk factors for chronic non-communicable diseases in the population, and it is also the main cause of death from cancer, cardiovascular disease and lung disease, causing serious health, economic and social problems. The current alcohol-abstinence drugs have limited therapeutic effects and still present a high relapse rate. It is an urgent need to develop effective drugs for the treatment of alcohol addiction. The multimodal mechanism of action of ligustrazine in the central nervous system indicates that ligustrazine is expected to be developed as a potential therapeutic drug for alcohol addiction. Our study investigated the therapeutic effect of ligustrazine on subjects with alcohol addiction and the mechanism of multimodal brain imaging by administering ligustrazine, in order to develop new targeted drugs for alcohol treatment and provide more effective diagnosis and treatment methods for clinical treatment.

Detailed Description
Background: Alcohol use disorders (AUD) is a common chronic disease with great harm to society, causing a huge disease burden and social burden. In recent years, a lot of progress has been made in the field of drug abuse in the field of neurobiology, but it is difficult to apply it to AUD. The clinical treatment of alcohol addiction has always been under the predicament of lack of medicine and drugs, and the development of new therapeutic intervention methods is urgently needed. Although the neurobiological mechanism of ligustrazine's efficacy is still unclear, its multimodal mechanism of action in the central nervous system suggests that ligustrazine is expected to be developed as a potential therapeutic drug for alcohol addiction. Objective: This study intends to develop a therapeutic drug that can effectively relieve alcohol withdrawal syndrome, promote the disappearance of addictive behaviors, and effectively prevent re-drinking for the main active ingredient ligustrazine of the traditional Chinese medicine Ligusticum chuanxiong. The implementation of this project will help to expand the new functions (new indications) of traditional Chinese medicine and its main active ingredient ligustrazine, which may be developed into an effective drug for the treatment of alcohol addiction, and explore its neuroimaging mechanism. METHODS: Eligible alcohol addiction cases were recruited and assigned to 3 treatment groups according to randomized double-blind procedure (conventional treatment
- placebo control group, conventional treatment + ligustrazine short-term treatment group, conventional treatment + ligustrazine maintenance treatment group ; about 100 cases in each group). After 15 days of group treatment, follow-up for 1 year, observe and compare the relapse rate of alcohol addiction, the duration of abstinence (days), the frequency and amount of drinking, the degree of craving, and other cognitive and psychological changes in each group, and record adverse reactions. Clinical efficacy and safety of ligustrazine on alcohol addiction. The changes of multimodal brain imaging in each group were analyzed, and the neural effects of ligustrazine treatment were explored. ②Recruit healthy controls ≥ 100 cases, match the sex and age with the cases, collect cognitive psychological indicators and brain imaging data at baseline and 1 year after baseline, and compare them in parallel with each treatment group to explore the treatment of alcohol addiction with Ligustrazine neural mechanism.

Outcome Measures
Primary Outcome Measures
- Relapse rate [Four week after treatment]
Percentage of participants who relapse by assuming that drinking alcohol on more than 3 days in a month in an unrestricted environment is re-drinking
Secondary Outcome Measures
- Time to maintain abstinence [Four week after treatment]
Measurement of exactly time(days) to maintain abstinence
- Frequency of alcohol consumed [Four week after treatment]
Assessment of frequency to consume alcohol
- Amount of alcohol consumed [Four week after treatment]
The amount of alcohol consumed would be measured.
- Change from baseline in alcohol craving by using Visual Analog Scale of Alcohol Craving at week 4. [Four week after treatment]
Alcohol-specific Visual Analog Scale is a valid measurements of craving for a alcohol. Possible scores range from 0 (no craving) to 10 (want to drink imediately). Change= (week 4 score - baseline score)
- Percent Mean Change in Blood Oxygen-level Dependent (BOLD) Scores [Four week after treatment]
BOLD fMRI signals evaluate different brain ROI
Eligibility Criteria
Criteria
Inclusion Criteria:
- Alcohol addiction:
①Aged 18~65 years old;
② Meet the diagnostic criteria of DSM-IV alcohol dependence;
③No clear history of neurological diseases in the past, no family history of mental diseases;
④Voluntary participation in research, with good follow-up and observation, and good compliance;
⑤ No obvious psychotic symptoms.
- Combined with the treatment indications of ligustrazine, the selected cases must meet the arteriosclerosis index ≥ 4:
Arteriosclerosis index (AI) = [total cholesterol (TC) - high-density lipoprotein (HDL)] ÷ high-density lipoprotein (HDL), the normal value of AI is <4, reflecting that the degree of arteriosclerosis is not serious or mild, The smaller the value, the lighter the degree of arteriosclerosis. If the arteriosclerosis index ≥ 4, it means that obvious arteriosclerosis has occurred, and the larger the value, the more serious the degree of arteriosclerosis.
Exclusion Criteria:
-
① Acute alcohol withdrawal phase, CIWA-Ar > 9 points;
-
Severe neurological or mental diseases caused by diseases other than chronic alcohol dependence: such as stroke, intracranial infection, brain tumor, schizophrenia, etc.;
-
Have experienced traumatic brain injury or other damage to brain tissue; ④ Taking any other psychotropic drugs, drug use or other substance dependence in the short term; ⑤ There are contraindications to the application of ligustrazine, or women are pregnant and other conditions that are not suitable for drug use; ⑥ There are conditions that are not suitable for head MRI examination, such as claustrophobia, metal objects in the body, etc.
