Title: Effects of Low Sodium Intake on the Anti-proteinuric Efficacy of Olmesartan in Hypertensive Patients With Albuminuria Through Open-label Randomized Trial
Brief Summary: Purpose of this study

1. Intensive education for low salt diet will be enhance the anti-proteinuric effect of Olmesartan, a popular anti-hypertensive drug of angiotensin II receptor blocker, in Koreans compared to conventional prescription of medication.
2. Intensive education for low salt diet will decrease the amount of 24 hour-urine sodium excretion compared to control group, effectively.
