Nicorandil

Uses

Nicorandil is used in the treatment of hypertension (high blood pressure), angina (heart-related chest pain), and heart failure.

How it Works

How Nicorandil works Nicorandil is a vasodilator that reduces the workload of the heart. Consequently, the heart muscle requires less blood and oxygen, which decreases the frequency and severity of angina attacks.

Side Effects

Common side effects of Nicorandil include headache, dizziness, flushing (a sense of warmth in the face, ears, neck, and trunk), palpitations, gastrointestinal ulcers, eye ulcers, and skin ulcers.

Expert Advice

  • You must continue to take Nicorandil as advised, usually for an extended period.
  • Nicorandil may cause headaches. Drink plenty of water and take a suitable painkiller. Inform your doctor if the headache does not resolve.
  • Nicorandil may cause dizziness or sleepiness. Do not drive or engage in activities that require concentration until you know how it affects you.
  • Avoid consuming alcohol while taking Nicorandil, as it may increase dizziness.
  • Do not take medications such as sildenafil or tadalafil (prescribed for erectile dysfunction) while on treatment with Nicorandil, as this may lead to low blood pressure.
  • Inform your doctor if you notice any bleeding from the anal passage, blood in vomit, or black stools.

Other Combinations

Nicorandil is classified as a potassium channel opener, which facilitates potassium removal from arterial walls, leading to artery dilation. This reduces the heart's workload and enhances blood and oxygen supply to the heart muscle. It is primarily prescribed for patients with stable angina who cannot tolerate other angina medications such as beta blockers or calcium channel antagonists.
