Can consider isosorbide mononitrate (30-120mg daily) as alternative to TID-dosed isosorbide dinitrate
Pharmacology of Isosorbide
FDA Approved Indications for Isosorbide Dinitrate Prevention or treatment of angina pectoris resulting from coronary artery disease - however, it is not recommended for use once the anginal episode has started because the onset of action is not sufficiently rapid enough to abort an acute anginal event
Talk with the doctor
Isosorbide dinitrate is a vasodilator used to treat angina in coronary artery disease
It works by relaxing blood vessels, which decreases the amount of work the heart has to do
Isosorbide dinitrate (Isordil) 20 mg three times per day: 40 mg three times per day: $180 ($245) Isosorbide dinitrate/hydralazine (Bidil) 20 mg/37
If you miss a dose of this medicine, take it as soon as possible
It often involves elevated filling pressures and a propensity to retain volume
Pharmacology of Isosorbide
you have early signs of a heart attack (chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating)
Isosorbide mononitrate will not treat an angina attack that has already begun
Isosorbide was previously available in an oral formulation for the reduction of intraocular pressure
When used regularly on a long-term basis, this helps prevent angina attacks from occurring
Both isosorbide mononitrate and dinitrate are only available on prescription
Loop diuretics should be used initially for control of volume overload, Isosorbide dinitrate is started at 20 mg orally 3 times a day (with a 12-hour nitrate-free interval) and increased to a target of 40 to 50 mg 3 times a day
For maintenance therapy, 10 mg to 40 mg, two or three times daily, is recommended
They produce these effects by entering vascular smooth muscle cells where they are metabolized to 1,2-glyceryl dinitrate and nitrite, via mitochondrial aldehyde dehydrogenase-2 (ALDH2 or mtALDH), and then nitric oxide and S-nitrosothiols ( figure 1 Vasodilators are useful in the management of hypertension, angina, heart failure, myocardial infarction, and more
Diuretics should be added as needed and dose should be titrated to achieve decongestion
Isosorbide dinitrate is a generic drug also sold under the brand names Dilatrate-SR, Dilatrate, and Isordil
Due to a lack of randomised controlled trials, the use of nitrates for management of AHF is not universally adopted

The short-acting tablet is usually taken as 10 mg to 40 mg by mouth 2 or 3 times daily with at least a 14 hour period of time per day where you don't take any doses

Active-controlled Study: In a second study of mortality, V-HeFT II, the combination of hydralazine and isosorbide dinitrate 75 mg/40 mg 4 times daily was compared to enalapril in 804 men with impaired cardiac function and reduced exercise tolerance (NYHA class II and III), and on therapy with digitalis glycosides and diuretics
Data were collected on mortality, LVEF, exercise tolerance, and echocardiography

Reduction of blood-nitrate concentrations to low levels for 4 to 12 hours each day usually maintains effectiveness in such patients

Isosorbide dinitrate is used to prevent chest pain ( angina) in patients with a certain heart condition ( coronary artery disease )
A 1986 trial demonstrated that the one-year mortality rate for the hydralazine and isosorbide dinitrate treatment group was 38% lower than the placebo control group
