What brand names does isosorbide mononitrate come in?
Isosorbide mononitrate is sold under multiple brand names depending on the country and manufacturer. Common examples you may see include Imdur (and its equivalents). Exact availability varies by market and pharmacy supply.
Is there a specific “main” brand in the U.S.?
In the U.S., one of the best-known brand versions is Imdur (isosorbide mononitrate extended-release). There are also generic equivalents in many places, depending on local approval and distribution.
Is it available as a generic too?
Yes. Isosorbide mononitrate is widely available as a generic drug, so patients often get the same active ingredient even when the brand name differs. Whether you see a brand prescription or a generic substitution depends on the prescriber’s instructions and local regulations.
Does the brand name change with formulation (ER vs IR)?
Yes. Isosorbide mononitrate can be made in different formulations, such as extended-release (ER) tablets and other controlled-release types. Brand names are commonly tied to a specific formulation, strength, and release mechanism.
How to verify the exact brand you’ll get
If you’re trying to confirm the brand on your prescription, check the label for:
- the strength (e.g., mg)
- the release type (extended-release vs other)
- the manufacturer (sometimes listed under generic products)
If you tell me your country (and whether your prescription says ER/extended-release), I can help narrow down the most likely brand names for that market.
