Hydralazine and isosorbide dinitrate may also be used for . Cohn JN, Tam SW, Anand IS, Taylor AL, Sabolinski ML, Worcel M. Isosorbide dinitrate and hydralazine in a fixed-dose combination produces further regression of left ventricular remodeling in a well-treated black population with heart failure: results from A-HeFT. For the treatment of Stage C Heart Failure with Reduced Ejection Fraction (HFrEF), the recommended fixed initial dose combination of hydralazine and isosorbide dinitrate is 37.5 mg hydralazine/20 mg isosorbide dinitrate 3 times daily with a maximum dose of 75 mg hydralazine/40 mg isosorbide dinitrate 3 times daily. Hydralazine and isosorbide dinitrate may also be used for purposes not listed in this medication guide. Presented by Anne L.

Your doctor may adjust your dose as needed. Yancy CW, et al. The mortality-risk reduction in the group treated with hydralazine and isosorbide dinitrate was 36 percent by three years. Heart failure with reduced ejection fraction (HFrEF): Treatment of heart failure as an adjunct to standard therapy in self-identified African-American patients. Although the basis for the beneficial effects of BiDil in the treatment of heart failure has not been determined, it may relate to its . 1. BACKGROUND: We examined whether a fixed dose of both isosorbide dinitrate and hydralazine provides additional benefit in blacks with advanced heart failure, a subgroup previously noted to have a favorable response to this therapy. 40, pp. Isosorbide dinitrate and hydralazine may enhance the effect of nitric oxide and reduce oxidative stress. 1 - 3 In particular, after the African-American Heart Failure Trial (A-HeFT) found that H-ISDN reduced mortality among black . Isosorbide dinitrate and hydralazine combination is used to treat heart failure in black patients. Background The combination of hydralazine and isosorbide dinitrate has been shown to provide incremental clinical benefits in patients with systolic heart failure (sHF) treated with "optimal" therapy (including an ACE inhibitor and beta-blocker). Isosorbide dinitrate dilates (widens) blood vessels, making it easier for blood to flow through them and easier for the heart to pump. Hydralazine: 300 mg daily in divided doses Hydralazine and isosorbide dinitrate may also be used for purposes not listed in this medication guide. 2 Isosorbide dinitrate is a venous dilator, while hydralazine is an arterial dilator.

BiDil is indicated for the treatment of heart failure as an adjunct to standard therapy in self-identified black patients to improve survival, to prolong time to hospitalization for heart failure, and to improve patient-reported functional status. Background: The addition of hydralazine-isosorbide dinitrate (H-ISDN) to standard heart failure therapy in The African-American Heart Failure Trial demonstrated a 43% reduction in mortality. -May decrease as low as hydralazine 18.75 mg-isosorbide dinitrate 10 mg three times a day if intolerable side effects occur; should titrate up as soon as side effects subside. Immediate effects of hydralazine-isosorbide dinitrate combination on exercise capacity and exercise hemodynamics in patients with left ventricular failure. A recent placebocontrolled study showed that in self-identified black patients with heart failure, ISDN/hydralazine, given in addition to current state-of-the-art pharmacotherapy for heart failure, reduces mortality and first hospitalizations due to heart failure and improves quality of life. Analysis of previous trials has shown that H+ISDN appears especially beneficial in African American patients. 2005;352(10):1041-1043.

This medication contains 2 drugs (hydralazine and isosorbide dinitrate) and is used with other medications to treat heart failure. Clinical trials have established the efficacy of hydralazine-isosorbide dinitrate (H-ISDN) therapy in patients with heart failure and reduced ejection fraction in terms of mortality, morbidity, and quality of life. Hydralazine and isosorbide dinitrate may also be used for . The use of direct acting vasodilators (the combination of hydralazine and isosorbide dinitrate -Hy+ISDN-) in heart failure with reduced ejection fraction (HFrEF) is supported by evidence, but rarely used.However, treatment with Hy+ISDN is guideline-recommended for HFrEF patients who cannot receive either angiotensin-converting enzyme inhibitors or angiotensin receptor blockers due to . The present study was, therefore, designed to compare the hemodynamic effects of combined oral therapy with hydralazine and isosorbide dinitrate to those of an infusion of sodium nitroprusside in patients with left ventricular failure.

Since history was improved in all subgroups after random assignment to therapy with hydralazine and isosorbide dinitrate, the data suggest that all patients with chronic congestive heart failure should be considered for such treatment.", Hydralazine and isosorbide dinitrate is a combination medicine used to treat heart failure. Taylor AL, Ziesche S, Yancy C, et al. This ethnic group is more likely to develop heart failure at a younger age than people of other ethnicities. Isosorbide dinitrate dilates (widens) blood vessels, making it easier for blood to flow through them and easier for the heart to pump. This showed a 34% reduction of mortality at 2 years of follo Strategies suggested to overcome nitrate tolerance are to increase the dosage, or adding hydralazine concurrently (75 mg four times per day). 39 The favourable interaction between hydralazine and nitrates has been demonstrated in the Veterans Heart Failure Trial (V-HeFT) and in the African-American Heart Failure Trial (A-HeFT). 1979 May; 43 (5):1009-1014.
