BiDil (isosorbide dinitrate and hydralazine hcl) 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.There is little experience in patients with NYHA class IV heart failure.Most patients in the clinical trial supporting effectiveness (A-HeFT) received a loop diuretic, an angiotensin con-verting enzyme inhibitor or an angiotensin II receptor blocker,and a beta blocker, and many also received a cardiac glycoside or an aldosterone antagonist.


Treatment with BiDil (isosorbide dinitrate and hydralazine hcl) should be initiated at a dose of one BiDil (isosorbide dinitrate and hydralazine hcl) Tablet,3 times a day.BiDil (isosorbide dinitrate and hydralazine hcl) may be titrated to a maximum tolerated dose,not to exceed two BiDil (isosorbide dinitrate and hydralazine hcl) Tablets, 3 times a day.

There is no adequate experience in heart failure with doses of BiDil (isosorbide dinitrate and hydralazine hcl) other than those recommended and no experience with use of individual components.

Although titration of BiDil (isosorbide dinitrate and hydralazine hcl) can be rapid (3-5 days),some patients may experience side effects and may take longer to reach their maximum tolerated dose. The dosage may be decreased to as little as one-half BiDil (isosorbide dinitrate and hydralazine hcl) Tablet 3 times a day if intolerable side effects occur. Efforts should be made to titrate up as soon as side effects subside.
