I'm trying to help my uncle who has angina and usually takes nicorandil, but he's now in the US. We're a bit worried about finding the right alternative medication here. Could you suggest what might work best for him in the States?

In the USA, a suitable alternative medication for angina that works similarly to nicorandil is Isosorbide Mononitrate. The recommended dosage for Isosorbide Mononitrate for angina is usually starting at 10 mg once daily, and can be increased to 20 mg once daily if needed. It is important to consult with a healthcare provider to determine the appropriate dosage and frequency for your uncle's specific condition.
