A new drug to lower cholesterol has entered the market that, when used in combination with existing drugs called statins, can reduce the risk of heart disease more effectively than statins alone. Patients who tried the new drug in a clinical trial were able to lessen their daily dose of statins without a corresponding increase in blood cholesterol levels. Statins alone, however, cost less, and the money patients saved on statins rarely surpassed the added cost of the new drug.
