www. Clinical trial results.org ERICA Trial: Background Ranolazine is a unique antianginal agent that has been effective in stable angina, but it has not been studied in the setting of maximum recommended doses of conventional antianginal agents.Ranolazine is a unique antianginal agent that has been effective in stable angina, but it has not been studied in the setting of maximum recommended doses of conventional antianginal agents. The purpose of this study was to determine if ranolazine improves angina in stable coronary patients with persisting symptoms despite maximum recommended dose of amlodipineThe purpose of this study was to determine if ranolazine improves angina in stable coronary patients with persisting symptoms despite maximum recommended dose of amlodipine.

www. Clinical trial results.org ERICA Trial: Summary Among patients with stable chronic angina already treated with the maximal dose of amlodipine, the addition of ranolazine was associated with a reduction in the average frequency of weekly anginal episodes at 6 weeks compared with placebo.Among patients with stable chronic angina already treated with the maximal dose of amlodipine, the addition of ranolazine was associated with a reduction in the average frequency of weekly anginal episodes at 6 weeks compared with placebo. Prior studies have demonstrated improvements in exercise tolerance with ranolazine alone or with standard doses of anginal medications, but the present trial extends these findings to patients with persistent angina despite maximal dosing of amlodipine.Prior studies have demonstrated improvements in exercise tolerance with ranolazine alone or with standard doses of anginal medications, but the present trial extends these findings to patients with persistent angina despite maximal dosing of amlodipine. Results were consistent in the subgroups shown, including those on long-acting nitrates and by degree of angina symptoms at baseline.Results were consistent in the subgroups shown, including those on long-acting nitrates and by degree of angina symptoms at baseline.
