Cohort 1 study is to assess the PK of Pregabalin controlled release formulation as compared to Pregabalin immediate release formulation. Cohort 1 subjects will be admitted to the clinic at Day 1. All subjects will receive multiple dosing for three days of YHD1119 or Pregabalin IR and will remain in the clinic until completion of all assessment on Day 19 including collection of PK sample. The treatment periods were separated by a washout period (10-17 days).
