Nicorandil 10 mg: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Is Nicorandil 10 mg?

Nicorandil 10 mg is a prescription medication used to prevent and treat chronic stable angina (chest pain) caused by reduced blood flow to the heart. It belongs to a class of medicines known as anti-anginal agents and has both potassium channel-opening and nitrate-like properties.

Nicorandil helps widen blood vessels, making it easier for blood and oxygen to reach the heart muscle. It is used to prevent angina attacks and is not intended for the immediate relief of sudden chest pain.

Nicorandil is commonly available in:

• 10 mg tablets
• 20 mg tablets
