In this study, 1000 cases of essential hypertension in changping district, Beijing, who are currently taking oral antihypertensive drugs and still have poor blood pressure control (> 130/80mmHg) are included. The duration of the study is 3+ (30±2) days, during which time the changing of antihypertensive drugs are avoided and the types and doses of drugs taken daily are recorded.
