      <study_design>Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Patients are allocated randomly with simple sequential allocation in one of the three study groups by help of sealed envelope and receive the intervention of the same group. The unit of randomization is patient. Sealed envelopes are delivered to expert. With each patient's visit, one of the envelopes is randomly selected by the patients and determines the study group. The stratification approach is not used.</study_design>

      <i_freetext>Intervention 1: Intervention group 2: One hour before the operation, the patient is given 600 mg of gabapentin capsules with some water. Paracetamol ampules are used to relieve postoperative pain in patients. Intervention 2: Intervention group 2: One hour before the operation, the patient is given 150 mg of pregabalin capsule with some water. Paracetamol ampules are used to relieve postoperative pain in patients. Intervention 3: Control group: One hour before the operation, the patient is given a placebo (domperidone 10 mg capsule) with a little water. Paracetamol ampules are used to relieve postoperative pain in patients.</i_freetext>
