Effect of Digestive Enzymes as Add on Therapy on Patients With Functional Dyspepsia.

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.

Primary outcomes

  1. Change in dyspeptic symptom

    Time frame: At baseline and then at week 2 and 4 after randomization

    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.

Secondary outcomes

  1. See the effect of digestive enzymes compared to first line treatment only

    Time frame: At baseline and then at week 2 and 4 after randomization

    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.

  2. Adverse events

    Time frame: Through study completion, an average of 1 year

    Patient reported adverse events will be documented

  3. Persistence of symptom improvement or recurrence of dyspeptic symptoms

    Time frame: At week 8 after randomization

    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.
