      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study, the block randomization with block size of 4. we used www.sealedenvelope.com website to generate random sequences. The the random list were provided to a epidemiologist who had no involvement in the selection of the type of drug. Then subjects were randomly assigned to two groups of Pregabalin and Cinnarizine, Blinding description: Patient blinding method: Since pregabalin is a capsule and cinnarizine is a tablet, for the similarity of the shape, we put the cinnarizine tablets into powder and inside the pregabalin capsule cover so that both drugs look the same.
Doctor's blinding method: The sealed medicine envelopes were given to a researcher who had no involvement in choosing the type of medicine. After the subjects entered the study and their baseline information was collected by the doctor, he sent them to the researcher to get the medicine, and the researcher gave one of the envelopes to the patients, and after that, it was determined in the sheet kept by the researcher that each What medicine did the patient take.</study_design>
