      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Randomization and allocation of each eligible patient in both intervention and control groups will be done by random block method. The intervention is in the form of three blinds so that the patient and the researcher and analyzer will not know the type of drug to treat patients.The file numbers are entered in Excel, then the random number is selected from the data analysis command. This study has 2 groups that can be numbered from 1 to 2, respectively. We also want to have 65 people in each group. As a result, sequences 1 to 2 should be repeated 65 times each time. It is clear that the repetition of each number occurs once in each group, so select 1 for repeating each number and 65 for repeating the sequence. In this way, 130 units will be produced. Which patient is included in which group, Blinding description: The intervention is in the form of three blinds so that the patient and the researcher and analyzer will not know the type of drug to treat patients.</study_design>
