BackgroundRanolazine is increasingly being prescribed for the treatment of chronic stable angina. This report describes an adverse effect that may be related to ranolazine.Case SummaryA 77-year-old white man with chronic renal insufficiency was evaluated for moderate dyspnea on exertion (DOE). Cardiac and pulmonary workup revealed nonobstructive coronary artery disease and mild obstructive lung disease. The patient had been taking ranolazine 500 mg daily for possible angina for the past 2 months. Given the temporal association of his symptoms with drug initiation, ranolazine was discontinued during the hospitalization. One month after discontinuing ranolazine, the patient's DOE had completely resolved; the only intervention had been discontinuation of ranolazine. The patient's Naranjo algorithm score was 3, indicating a possible adverse drug reaction.ConclusionsNo previous cases of ranolazine-related DOE requiring drug cessation have been published. Ranolazine may be associated with DOE in this elderly man.Copyright 2010 Excerpta Medica Inc. All rights reserved. Published by EM Inc USA.. All rights reserved.
