What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The efficacy rate on gastroscopy	The efficacy rate is obtained from the following formula using the subject whose erroneous score is improved by 50% or more as compared with before the study drug administration. The efficacy rate(%) = (number of effective cases)/(all cases) x 100 Effective case is determined by the grade change of erosion. A case in which the grade changes from 4 to 2 or 1, from 3 to 1, or from 2 to 1 is judged as an effective case.	Week 0, Week2

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cure rate on gastroscopy	Judging from the gastroscopic examination as normal (no erosion), the cure rate is obtained as follows. Cure rate(%) = (number of cures(no erosion))/(all cases) x 100	Week 0, Week2
