Effect of Jaeumgeonbi-Tang on Chronic Subjective Dizziness: A Randomized, Double-Blind, Parallel-group, Placebo-Controlled Trial

The goal of this study is to assess the safety and efficacy of JGT (Jaeumgeonbi-Tang). A randomized, double-blind, parallel-group, placebo-controlled clinical trial was conducted and changes in symptoms and quality of life of the patients were evaluated.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study's protocol was designed to assess the efficacy of JGT (Jaeumgeonbi-Tang) for chronic subjective dizziness.

  • This design of the study is a randomized, double-blind, parallel-group, placebo-controlled design.
  • Symptoms and quality of life of chronic subjective dizziness patients will be evaluated.
  • Dizziness severity and quality of life of the patients will be evaluated using DHI (Dizziness Handicap Inventory) (1) before treatment (baseline), (2) after 2 weeks, and (3) after 4 weeks of JGT treatment.
  • Blood samples of the patients will be gathered before and after JGT treatment for pathophysiological analysis.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

[Inclusion Criteria]

  • Chronic subjective dizziness patients, aged from 20 to 65
  • DHI (Dizziness Handicap Inventory) score ≥ 24
  • Those who can fully comprehend the general protocol of this study and voluntarily agree to participate

[Exclusion Criteria]

  • Inner ear disease (benign paroxysmal positional vertigo, vestibular neuritis, Meniere's disease, etc.)
  • Dizziness secondary to specific diseases such as hypoglycemia, recent stroke (within the last 6 months), or heart disease.
  • Use of medications that could influence the result of the study (anticonvulsants, sedatives, antidepressants, sleeping pills, prostate medicine, Parkinson's drug, dementia drug, etc.)
  • Pregnancy, breastfeeding, or plans of becoming pregnant
  • Functional dyspepsia (persistent, recurring abdominal pain, or discomfort)
  • Other allergic diseases
  • Ineligibility for other reasons in the opinion of the research clinician (when the physician determines that there are significant physical or mental defects that the patient cannot understand and follow the protocol)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame

Time Frame: Change from Baseline DHI score at 4 weeks
The DHI (Dizziness Handicap Inventory) is a 25-item self-report questionnaire that quantifies the effect of dizziness on daily life by measuring the self-perceived handicap of the patients.
