      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: For the purpose of randomization, 40 cards are prepared, 20 of which are labeled with the letter A and 20 with the letter B, and each card is placed in an aluminum envelope and placed inside a box. When the patients arrive, one of the envelopes will be randomly selected and opened. Based on the letter selected inside, the patient will be assigned to group A or B, Blinding description: In this study, the placebo will be prepared in a similar shape and color to the original drug. The drug and placebo will be identified by a code. The patient and the person evaluating the treatment outcome will be unaware of the type of treatment.</study_design>
