      <study_design>Randomization: Randomized, Blinding: Not blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: A randomized block is used to randomize the patients under study and to fully observe the randomness of placement in the control group and the sample group because the inclusion process requires randomization due to the ongoing recruitment. Based on the calculated sample size, the sample size in each group is 24 people for easier application of random blocks to randomize the members of each group. Permutations are considered as 6 permutations according to 2 groups: AABB, ABAB, BBAA, BABA, BAAB, ABBA. The permutations are written on 6 cards and the selection of permutations and their order will be randomly selected from among the cards. The order of exit of the cards is written and will determine the order of recruitment of intervention groups based on it. An individual randomization unit will be used for the study. The information of the registered persons will be anonymous and without their personal information.</study_design>

      <i_freetext>Intervention 1: Intervention group: Ursodeoxycholic acid tablets with a dose of 9-10 mg/kg produced by Exir Pharmacy, will be taken orally at bedtime once a day. The duration of treatment is six weeks. Intervention 2: Control group: A placebo with the same appearance as the drug of the intervention group will be provided by a similar pharmaceutical company (Exir Pharmacy) and does not contain any active substance. It will be taken once a day, orally and at bedtime. The duration of treatment will be 6 weeks.</i_freetext>
