About Isosorbide Dinitrate and its cost

What is this medication? Isosorbide dinitrate is a type of medication known as a nitrate that is primarily used to prevent chest pain, also called angina, in patients with coronary artery disease. It functions by relaxing the smooth muscles found in the walls of blood vessels, which leads to the widening of both arteries and veins. By dilating these vessels, the medication reduces the amount of work the heart must perform to pump blood and enhances the delivery of oxygen and nutrients to the heart muscle itself.

This prescription drug is intended for the long-term management of heart conditions rather than for the immediate treatment of an acute angina attack. It is usually taken on a consistent daily schedule to help decrease how often chest pain occurs and to improve a patient's ability to engage in physical activity. Because the body can develop a tolerance to nitrates if they are present in the system constantly, healthcare providers often recommend a specific dosing schedule that includes a drug-free interval each day to maintain the medication's effectiveness.

Isosorbide Dinitrate is made by Lannett. Like most brand-name drugs, it's priced at a high list price — but patients rarely pay that list price. The options above are the real paths most people use to get it affordably.

Common questions

What's the cheapest way to afford Isosorbide Dinitrate?

It depends on your insurance. On Medicare, apply for the manufacturer's Patient Assistance Program (PAP) — it gives the drug free if you meet income requirements. With private insurance, the manufacturer copay card usually drops your copay to $0-$25. Uninsured patients should compare the PAP with Cost Plus Drugs cash price.

Can I use a copay card with Medicare for Isosorbide Dinitrate?

No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But Lannett has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.

Does my Medicare Part D plan cover Isosorbide Dinitrate?

Part D coverage varies by plan. We query the CMS Prescription Drug Plan file to show you what percentage of plans cover it and at what tier. For your exact copay, pick "Medicare" above and check your plan's Summary of Benefits, or log in to Medicare.gov.

How long does a Patient Assistance Program take?

Most PAPs take 2-6 weeks from application to first fill. Ask the manufacturer about a "bridge supply" — many will ship 30 days free while your application is being reviewed so you don't go without the drug.

What if I have a high-deductible plan?

For generics, Cost Plus Drugs cash price is often cheaper than your deductible-phase copay. For brand names, the manufacturer copay card almost always wins. A GoodRx coupon can be a last resort for uncovered drugs, but it doesn't count toward your deductible.

Are there charity grants for Angina pectoris?

Charities like HealthWell Foundation, PAN Foundation, Good Days, and the National Organization for Rare Disorders provide copay help for specific conditions. Funds often run out mid-year — apply early. We list the specific grants for your condition in the options above.
