What can replace Imdur 60 mg (isosorbide mononitrate) for angina?
Imdur 60 mg is brand isosorbide mononitrate, used to prevent angina (chest pain) by preventing blood vessels from tightening. Common alternatives are other isosorbide mononitrate products or other long-acting nitrate medicines, chosen based on the dose form you need (usually once-daily for the extended-release version).
Because “Imdur 60 mg” specifically points to an extended-release tablet at 60 mg, the most direct switch is typically:
- Another extended-release isosorbide mononitrate product at a similar strength
- Sometimes a different manufacturer’s 60 mg extended-release formulation (if available)
If you tell me your country (and whether your tablet is definitely extended-release), I can narrow the closest match.
Are generic isosorbide mononitrate tablets available instead of Imdur?
In many markets, Imdur’s active ingredient (isosorbide mononitrate) is available as generics or from different manufacturers. In that case, a “generic Imdur” alternative is usually the simplest option: same active ingredient and the same release type (extended/modified release), at a comparable daily dose.

What about other long-acting nitrate alternatives (if you can’t use isosorbide mononitrate)?
If you can’t take isosorbide mononitrate (for example, due to side effects or supply issues), clinicians sometimes use another long-acting nitrate instead. The most common class alternatives are long-acting formulations such as:
- Long-acting isosorbide dinitrate (different dose forms and release patterns)
- Other long-acting nitrate products (availability depends on your country)
Whether these are appropriate depends on your exact indication (stable angina vs other uses), your current dose schedule, blood pressure, and how often you get symptoms.
Is there a “dose-equivalent” substitution for 60 mg Imdur?
Dose equivalence depends on formulation (extended-release vs immediate-release) and the specific product. A key risk is accidentally switching from extended-release to immediate-release (or vice versa), which can change blood levels and side effects.
So the safe rule is:
- Match the release type (extended-release tablet to extended-release tablet), and
- Use the prescriber/pharmacist’s recommended dose for substitution.
What side effects or safety issues make people look for alternatives?
Patients commonly ask for alternatives because of nitrate side effects such as:
- Headaches (very common)
- Dizziness or low blood pressure
- Flushing
Also, nitrates have important interaction rules. The biggest one is that nitrates should not be used with PDE-5 inhibitors for erectile dysfunction (like sildenafil, tadalafil, etc.) because it can cause dangerous low blood pressure. Your pharmacist can confirm your specific interaction risk.
What information should you share so I can name the closest alternatives?
If you want a precise “Imdur 60 mg alternative” list (specific brands/generics and what’s closest), tell me:
1) Your country
2) Whether it’s an extended-release tablet (often once daily)
3) Your reason for switching (side effects, cost, availability, or interaction)
4) Any other heart/angina meds you take (especially PDE-5 inhibitors)
