About this study
Official title: Effect of Digestive Enzymes as Add on Therapy on Patients With Functional Dyspepsia - A Randomised, Open Label Trial
The goal of this clinical trial is to assess the effect of digestive enzymes in improving dyspeptic symptoms in patients with functional dyspepsia. It will also assess about the safety of drug by recording the patient reported adverse events. The main questions it aims to answer are:
Does drug digestive enzymes has any effect on patients with functional dyspepsia? What medical problems do participants have when taking drug digestive enzymes? Researcher will compare drug digestive enzymes to a control group taking standard first line treatment only.

Participants will:
Take drug digestive enzymes 325 milligrams 3 times daily, every day for 4 weeks along with standard first line treatment. A second group will be taken as control arm who will be kept on standard first line treatment only for 4 weeks. They will visit the hospital 2 weekly, and their symptoms will be assessed by a 5-point Likert Scale at baseline, week 2 and 4. Additionally, patient reported adverse events will be documented.

| Study group | Role | What they receive |
|---|---|---|
| Group-A | Experimental | Drug: Digestive enzyme 325mg + first line treatment This group will get digestive enzyme 325 mg 3 times daily along with first line treatment (PPI 20 mg twice daily and Prokinetics such domperidone 10mg three time daily) for 1 month Receives: Drug: Digestive enzyme 325mg |

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in dyspeptic symptom
The change of four dyspeptic symptoms (Postprandial fullness, Early Satiety, Epigastric pain, Epigastric burning) will be assessed by a 5-point Likert Scale. The four main symptoms of dyspepsia, each will be graded as 1 (No problem), 2 (Mild problem, can be ignored when not thinking about it), 3 (Moderate problem, cannot be ignored but does not influence daily activities), 4 (Severe Problem, influences concentration on daily activities), 5 (Very severe problem, markedly influences daily activities or requires rest or both). The total minimum value is 4 and maximum value is 20. Higher score means worse outcome.
Measured: At baseline and then at week 2 and 4 after randomization
Secondary outcomes (3)
See the effect of digestive enzymes compared to first line treatment only
Effect of digestive enzymes on four dyspeptic symptoms (Postprandial fullness, Early Satiety, Epigastric pain, Epigastric burning) will be assessed and compared to first line treatment only by a 5-point Likert Scale. The four main symptoms of dyspepsia, each will be graded as 1 (No problem), 2 (Mild problem, can be ignored when not thinking about it), 3 (Moderate problem, cannot be ignored but does not influence daily activities), 4 (Severe Problem, influences concentration on daily activities), 5 (Very severe problem, markedly influences daily activities or requires rest or both). The total minimum value is 4 and maximum value is 20. Higher score means worse outcome.
Measured: At baseline and then at week 2 and 4 after randomization
Adverse events
Patient reported adverse events will be documented
Measured: Through study completion, an average of 1 year
Persistence of symptom improvement or recurrence of dyspeptic symptoms
Persistence of symptom improvement or recurrence of four dyspeptic symptoms (Postprandial fullness, Early Satiety, Epigastric pain, Epigastric burning) after discontinuation of digestive enzymes will be assessed and compared by a 5-point Likert Scale. The four main symptoms of dyspepsia, each will be graded as 1 (No problem), 2 (Mild problem, can be ignored when not thinking about it), 3 (Moderate problem, cannot be ignored but does not influence daily activities), 4 (Severe Problem, influences concentration on daily activities), 5 (Very severe problem, markedly influences daily activities or requires rest or both). The total minimum value is 4 and maximum value is 20. Higher score means worse outcome.
Measured: At week 8 after randomization

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Digestive enzyme 325mg and PPI 20 mg + Domperidone 10 mg in people with Dyspepsia and Functioanl Dyspepsia, run by Rakibul Mostafa at 1 site in Bangladesh.
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 2 inclusion and 6 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: opening soon, as of the sponsor's last update on 11 May 2026. 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 Bangladesh. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Rakibul Mostafa (+8801837031585, rakibmasuk96@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in dyspeptic symptom (time frame: At baseline and then at week 2 and 4 after randomization). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 11 May 2026; AzTrials last refreshed its copy on 7 Nov 2026.
