Title

Study to Compare the Efficacy and Safety of Pitavastatin and Pravastatin in Elderly Patients
Study Of Pitavastatin 1 Mg Vs. Pravastatin 10 Mg, Pitavastatin 2 Mg Vs. Pravastatin 20 Mg And Pitavastatin 4 Mg Vs. Pravastatin 40 Mg (Following Up-Titration) In Elderly Patients With Primary Hypercholesterolemia Or Combined Dyslipidemia

The purpose of this study is to compare the efficacy and safety of pitavastatin with that of pravastatin in elderly patients
Following a wash-out dietary lead-in period, patients will receive either Preavastatin or Pitavastatin during 12 weeks, in order to establish the efficacy of pitavastatin in reducing cholesterol levels.
