ER niacin (PrNiaspanFCT®) is an extended-released form of niacin, also known as vitamin B3. Niacin is effective in reducing cholesterol levels in the blood. This drug has been known for a long-time to treat dyslipidemia and it is used to improve favourably all the lipoprotein risk factors for artherosclerotic disease, particularly in HIV-infected patients. Recent scientific research shows that regular consumption of niacin-rich foods may also provide protection against Alzheimer's disease and age-related cognitive decline.
