Frequently asked questions

What does Dilatrate-SR treat?
Dilatrate-SR (Isosorbide Dinitrate) may be used to treat angina pectoris, coronary disease, cyanosis, gastroesophageal reflux, heart failure, poisoning, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
How does Dilatrate-SR work?
Dilatrate-SR is a nitrate vasodilator. Nitrate vasodilators are converted in the body into nitric oxide, which relaxes the smooth muscle in blood vessel walls and widens them. This mainly opens up the veins, reducing how hard the heart must work and relieving chest pain.
How much does Dilatrate-SR cost?
Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $6.05 for 30, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins. Pharmacies pay less for a same-class option, Nitrostat — about $4.23 on the same basis.
Is there a coupon or discount for Dilatrate-SR?
pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Dilatrate-SR. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
