Control Group
Drug: control group
routine treatment
Other Name: Routine Treatment

Detailed Description:

Efficacy index:

After 12 weeks of treatment, the change difference of arteriosclerosis related biomarker between 4 modality groups.

Pharmacokinetics:

After 12 weeks of treatment, the study medication plasma concentration including of Probucol ,Cilostazol , Cilostazol metabolism OPC-13015 and OPC-13213 will be measured.

Safety evaluation:

Analysis the abnormality of Adverse Event, Vital Sign, Physical Examination, 12-lead ECG, and Laboratory Tests (including blood routine examination, routine urine analysis, blood biochemistry examination, glycosylated hemoglobin) in 4 modality groups.
