Primary Outcome Measures:
  • Number of Participants With Adverse Events and Adverse Reactions [ Time Frame: Throughout 1 year of study ] [ Designated as safety issue: Yes ]

    An adverse event is any unfavorable medical event occurring in a subject to whom an investigational product is administered, and a causal relationship between the administered investigational product and an adverse event is not always clarified.

    That is, an adverse event is any unfavorable or unintended sign (including an abnormal change in laboratory test values), symptom, or disease, and a causal relationship to the relevant investigational product is not considered.

    Any adverse event that was treatment-related was considered an adverse reaction.

    • Sex: both males and females
    • Inpatient/outpatient: Out-patients

Exclusion Criteria:

  • Patients for whom any of the following is applicable:

    • Patients whose fasted triglyceride level measured at the start of the observation period or the treatment period exceeds 500 mg/dL
    • Patients with homozygous familial hypercholesterolemia
    • Patients with creatine phosphokinase (CPK) > 2x upper limit of normal (ULN) measured at the start of the observation period or the treatment period.

    • Patients who are using any of the following drug from after the start of the observation period: itraconazole, miconazole, atazanavir, saquinavir mesilate
    • Patients with a history of ezetimibe use
    • Patients with hyperlipidemia associated with the following diseases:

      • Hypothyroidism
      • Obstructive gall bladder or biliary disease
      • Chronic renal failure
      • Pancreatitis
    • Patients with hyperlipidemia associated with concomitant use of drugs having adverse effect on serum lipids, etc
    • Patients who have received an investigational drug within 4 weeks of the start of the observation period
    • Other patients deemed not appropriate for study entry by the investigator
