Heart Disease :: Ranexa, ranolazine – for treating chronic angina – chest pain
The Food and Drug Administration (FDA) announced the approval of Ranexa (ranolazine), a new drug for the treatment of chronic angina. Ranexa, a new molecular entity (NME), is the first drug approved to treat chronic angina in over ten years. Although several pharmacological activities of ranolazine have been described, the precise way the drug works is not fully understood. Because Ranexa affects electrical conduction in the heart (prolong the QT interval), it should only be used by patients who have not responded to other anti-anginal (long-acting nitrates, calcium channel blockers and beta blockers) drugs.
