'Quadpill' shows promise in hypertension: study

First there was the polypill, now a quadpill has been developed by Australian researchers as a smarter way of tackling hypertension.

Combining four antihypertensives in low doses will allow patients to reap the benefits of their synergistic effects and also minimise side effects, according to researchers at the George Institute of Global Health in Sydney.

In a pilot study, they show that a single capsule containing quarter doses of irbesartan, amlodipine, hydrochlorothiazide and atenolol could lower blood pressure to target levels in just four weeks.
