The other groups took either a single drug or different combinations of the medicines in the Polycap pill. The study showed that Polycap lowered blood pressure and cholesterol without many side effects. Doctor Yusuf said the single pill, taken once a day, could reduce the average person's risk of heart disease and stroke by about half.

And one pill would cost less than several pills. Other heart doctors say heart disease prevention is important but not necessarily with pills. They say patients might be able to get the same results with changes in diet and exercise. Doctors say that more research on Polycap is needed. They say the drug should be...
