The Food and Drug Administration (FDA) added new safety warnings to cholesterol-reducing statin drugs on Wednesday, noting increased risks of Type 2 diabetes and memory loss for patients who take the medications.The changes to the prescribing information apply to the class of statins, including many popularly prescribed drugs such as Lipitor (atorvastatin), Crestor (rosuvastatin), Zocor (simvastatin) and Vytorin (simvastatin/ezetimibe). The new warnings are based on results from the latest clinical trials and reports of adverse events from patients, physicians and drugmakers.
