EFFICACY OF ORAL AROEIRA (Schinus Terebinthifolia Raddi) COMPARED TO OMEPRAZOLE IN PARTICIPANTS DIAGNOSED WITH FUNCTIONAL DYSPEPPSIA: A RANDOMIZED AND DOUBLE-BLIND STUDY

This is a prospective, randomized, double - blind study of 474 male and female volunteers with dyspeppsia diagnosed at the Oswaldo Cruz University Hospital Gastroenterology Outpatient Clinic from March 2025 to March 2027.

Hypothesis:

As a non-inferiority study, the hypothesis is that the use of oral Aroeira (Schinus terebinthifolia Raddi) for the treatment of participants diagnosed with functional dyspepsia efficacy not inferior to therapy based on the use of omeprazole.

Detailed Description

This is a prospective, randomized, double - blind study of 474 male and female volunteers with dyspeppsia diagnosed at the Oswaldo Cruz University Hospital Gastroenterology Outpatient Clinic from March 2025 to March 2027.

Hypothesis:

As a non-inferiority study, the hypothesis is that the use of oral Aroeira (Schinus terebinthifolia Raddi) for the treatment of participants diagnosed with functional dyspepsia efficacy not inferior to therapy based on the use of omeprazole.

The initial proposal of the project was a prospective, comparative and double blind study between aroeira and omeprazole together with antibiotic treatment for patients diagnosed with gastritis caused by Helicobacter pylori, whose dosage of aroeira (Schinus terebinthifolia Raddi) was 1 tablet of 640 mg, every 12 hours for 4 weeks and omeprazole was 1 capsule of 20 mg, 12/12h, for 4 weeks.

Due to Anvisa requirements, and taking into account the current rationale for gastritis related to this infection, we analyzed that a project with gastritis without the association with H. pylori would not be ideal. So, we are proposing a comparative study with the same drugs (aroeira versus omeprazole) in evaluating the complete relief of dyspeptic symptoms in Dyspepsia Functional. In this new proposal, the N will be 474 participants, maintaining a 1:1 ratio. Research participants will be those who report at least 1 of the 5 dyspeptic symptoms (nausea, heartburn, pain epigastric pain, abdominal discomfort aggravated/relieved by meals and feeling of early satiety) with onset more than 6 months, lasting at least 3 months and excluding other diagnoses by upper digestive endoscopy (EDA).

Our primary objective will be "Compare the effectiveness of oral mastic (Schinus terebinthifolia Raddi) versus omeprazole in relieving complete description of the symptoms of functional dyspepsia. The secondary objectives will be:

  1. Evaluate the improvement in the quality of life of participants with dyspeptic symptoms within each treatment (before and afterwards) and between aroeira versus omeprazole at the end of treatment;
  2. Evaluate complaints within each treatment (before and after) and between oral mastic versus omeprazole at the end of the treatment treatment;
  3. Evaluate possible adverse events to treatment with oral mastic versus omeprazole therapy reported by the participant.

Clinical Trial Protocol Oral Aroeira medicine (Schinus terebinthifolia Raddi) Version 03 of 14-June-2023 HB-F3-01/2019 Sponsor: INFAN - Indústria Química Farmacêutica Nacional S/A

The dosage of this study will be: 1 tablet of oral Aroeira (Schinus terebinthifolia Raddi) of 640mg, once a day, at least period of 4 weeks, and omeprazole, 1 capsule of 20mg, once a day, for a period of 4 weeks.

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

14 years to 76 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

To be eligible to participate in this study, an individual must meet all of the following criteria:

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
Complete relief dyspeppsia symptom
Time Frame: 30 days after the first day treatment
Assessment of the proportion of participants with complete relief of dyspeptic symptoms. Complete relief of symptoms will be considered if the scores obtained in items #3, #5 and #7 of the ROME III questionnaire are lower than or equal to their respective reference values for the diagnosis of each symptom of functional dyspepsia.
30 days after the first day treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Life quality Improvement
Time Frame: 60 days after the first day treatment
Assessment of the proportion of improvement in quality of life using the SF-36 quality of life questionnaire, taking into account the domains "Functional capacity", "Limitation due to physical aspects", "Pain", "General health status", "Vitality ", "Social aspects", "Emotional aspects" and "Mental health" generating a continuous numerical variable (between 0 and 100, where 0 is bad and 100 is good) corresponding to each domain.
