      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: For randomization, we will use the method of Balanced Block Randomization (block size: 4). For this purpose, we prepare four sheets of paper. On the two sheets, we write the I meaning "Intervention" and on the other two sheets we write the P meaning "Placebo". Mix the sheets together and place them in the desk drawer. When referring to any of the eligible patients, one of the sheets was randomly taken out, and based on this sheet, I or P was assigned to one of the two groups of intervention (melatonin recipient) or comparison (placebo recipient). They will be. Extracted tabs will not be returned to the drawer until all four tabs have been extracted. After randomly pulling out all four sheets, all the sheets are returned to the drawer and the above procedure will be continued for the next four patients until the desired sample size (60 patients) is reached, Blinding description: Both the intervention and control groups will receive drugs with the same appearance, the intervention group will receive melatonin in addition to the standard drugs, and the control group will receive standard drugs and placcebo. The drugs for each group are specified with a special code and the patient and the treating physician will be unaware of the type of drug used by the patients. Therefore, the study will be conducted in a double-blind manner.</study_design>
