Atorvastatin was linked to one extra case of diabetes for every 160 patients treated. Experts said the benefits of statins still outweighed any risks. Statins are a group of commonly prescribed drugs that lower the levels of bad cholesterol in the blood. This reduces the chances of a heart attack or stroke.
All drugs come with side-effects, but a team of researchers from hospitals in Toronto said there had been controversy around the risk of diabetes with different statins. They looked at medical records of 1.5 million people over the age of 66 and compared the incidence of diabetes between people taking different statins. Their report said: “We found that patients treated with atorvastatin, rosuvastatin, or simvastatin were at increased risk of new onset diabetes compared with those treated with pravastatin. “Clinicians should considers this risk when they are contemplating statin treatment for individual patients. “Preferential use of pravastatin… might be warranted.”
