High levels of niacin, an essential B vitamin, may raise the risk of heart disease by triggering inflammation and damaging blood vessels, according to new research. The report, published Monday in ...

[42] Medications include antiretrovirals, anti-seizure drugs, glucocorticoids, systemic antifungals such as ketoconazole, cholestyramine and rifampicin.
