Amlodipine/valsartan single pill combination therapy in Chinese patients not controlled on previous monotherapy

The majority of hypertensive patients requires combination therapy to reach target blood pressure (BP), usually a value <140/90 mmHg (1,2). On the basis of data available from published hypertension treatment trials, a rule of thumb has recently been proposed whereby approximately a third or less of unselected hypertensive patients will have their BP controlled with a single agent while two third need at least two drugs (3).
