Trial of Itopride 150mg Once a Day Versus Itopride 50 mg Thrice a Day; in Patients With Functional Dyspepsia

The study is conducted in patients with functional dyspepsia or chronic gastritis. The purpose of this study is to:

* assess whether the dose of Itopride Hydrochloride 150 mg extended release tablets, taken once daily has a similar effect on gastrointestinal symptoms caused by gastric dysmotility and delayed gastric emptying, like bloating sensation, early satiety, postprandial fullness, upper abdominal pain or discomfort, anorexia, heartburn, nausea and vomiting in functional (non-ulcer) dyspepsia or chronic gastritis, as Itopride Hydrochloride 50 mg film coated tablets administered thrice a day. * investigate assessment of the treatment provided to each participant. * monitor safety and tolerability of Itopride Hydrochloride 150 mg extended release tablets, taken once daily before one of the main meals (preferably same meal throughout the treatment) and Itopride Hydrochloride 50 mg film coated tablets thrice daily before meals.

End Result: Maximum severity score is 40, symptom free=0, very mild =1-4, mild=5-8, moderate=9-15, severe is 16-40

Secondary outcomes

    Time frame: 4 weeks

    Change in the overall severity of functional dyspepsia between baseline and week 4, as measured by the Leeds Dyspepsia Questionnaire (LDQ) severity score. Change in the overall severity of functional dyspepsia between baseline and week 8, as measured by the Leeds Dyspepsia Questionnaire (LDQ) severity score consisting of 15 questions, where questions 1-8 are used to measure the severity, on a scale of 0 to 5 (0= absence, 1= very mild, 5=very severe).

  2. Disease Specific Quality of Life (Nepean Dyspepsia Index NDI) Assessed at Baseline and Week 8 in Terms of Change in % of Functional Ability.

    Time frame: 8 weeks

    To assess quality of life for the two treatment arms using Disease Specific Quality of Life (Short Form - Nepean Dyspepsia Index SF-NDI) at baseline and end of treatment. The SF-NDI measures dyspepsia's impact on quality of life, with scores ranging from 10-50 (higher = worse). It includes five subscales-tension/anxiety, daily activities, eating/drinking, knowledge/control, and work/study-each with two questions rated on a 5-point Likert scale (1 = not at all, 5 = extremely). Step-1: sum of scores, step-2: converted to %disability, Step-3: convert to %functional ability (100-%disability). Higher score represents higher Quality of Life and lower scores lower Quality of Life.
