Detailed Description

This study is a multicenter, open-labeled, prospective, phase IV, observational study for patients visiting the gastroenterology department. The purpose of this study is to examine the treatment profile of approximately 1,000 adult patients with gastroesophageal reflux (GERD) who begin raberpazole sodium treatment for 4 months and assess patients' adherence to the study drug. The primary objective is to examine the treatment profile of gastroesophageal reflux in the secondary or tertiary clinical center. The secondary objective is to examine GERD patients' adherence to the study drug (rabeprazole sodium) during the treatment period. Of the patients who visit the study centers and complain about gastroesophageal reflux symptoms during the study period, those who are deemed to need rabeprazole sodium administration at the investigator's discretion will be considered for this study. The main outcome measures are the patterns of gastroesophageal reflux management (eg. treatment duration of initial therapy etc) and the compliance of proton pump inhibitor treatment.The compliance data (number of tablets taken) will be calculated at the clinical visit by counting the number of dispensed tablets that are remaining. Also, investigators will observe the gastroesophageal reflux symptom free rate at the end of initial therapy, gastrointestinal (GI) symptom relief and safety information at each visit. Study period is up to 4 months. During the study, no standardized treatment is stipulated, and patients may receive any treatment considered by their physicians. Rabeprazole sodium 10 mg - 20 mg tablet once daily for 4months.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Among the patients who visit the department of gastroenterology with gastroesophageal reflux disease and who need rabeprazole treatment according to the doctor's discretion

Description

Inclusion Criteria:

  • Patients complaining about heartburn or acid regurgitation, the typical GERD symptoms, more than once a week
  • After a full explanation about the observational study, patients who fully understand it and sign a written consent form

Exclusion Criteria:

  • Patients who took rabeprazole sodium within the last four weeks
  • Patients who are hypersensitive to the active ingredient of rabeprazole sodium or benzimidazole
  • Patient with other digestive tract diseases other than GERD (gastrointestinal cancer, liver disease, pancreatic disease, peptic ulcer, inflammatory digestive tract diseases [in case of ulcer, however, scars from healed ulcer may be included])
  • Patients with other severe accompanying diseases including renal impairment, cerebrovascular disease, cardiovascular disease and severe respiratory disease
  • Patients who must constantly take Proton Pump Inhibitors other than rabeprazole sodium during study period
  • Pregnant or lactating women

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
Time Frame
GERD Symptom improvement
Time Frame: 4 weeks, 16 weeks
4 weeks, 16 weeks

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
Time Frame
Actual administrating dosage of PPI during the GERD treatment period
Time Frame: 16 weeks

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
