      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Based on the two study arms and three categories of IBS (predominant constipation, diarrhea, or mixed) diagnosed using the Rome IV criteria, a randomization list is created using an online randomization software in blocks of six. Through this method, a unique code is generated for each individual. Each code, along with the medication category A or B, is placed in a sealed envelope. Upon the individual's entry into the study and in the order specified by the randomization list, the envelope is opened by the diagnosing physician, and the patient is randomly assigned to either the treatment group receiving drug A or drug B. Both the physician and the patient are blinded to the content of drugs A and B. The patient is provided with the assigned medication code, and they receive a bottle of medication from category A or B from the pre-determined pharmacy, which holds these bottles, Blinding description: Until the end of data collection, only the pharmacist will be aware of the content of drugs A and B, and until that time, all participants and researchers will remain blinded.</study_design>
