      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Single, Purpose: Supportive, Other design features: The random blocks are divided into two groups: memantine (A) and placebo (B)&#13;
This study is two-sided, and only the doctor responsible for distributing the drug knows its name, and the patient and the other physician who record the pain score and calibrate score after the operation are unaware of the type of medication used to reduce the associated bias or bouts. Intervention and evaluation of consequences are used in this way, and this way it is possible to measure objectively the outcome.</study_design>

      <hc_freetext>Condition 1: pain. Condition 2: Hysterectomy.</hc_freetext>
      <i_freetext>Intervention 1: Memantine, 20 mg oral tablet, one hour before surgery. Intervention 2: placebo.</i_freetext>
