How Do Non-nitrates Antianginals Work?

Non-nitrates are a class of drugs used for treating chest pain (angina).

Non-nitrates prevent calcium flow to the heart causing the heart to relax, thereby improving blood flow to the heart muscles. As a result, the symptoms of angina are reversed.

Non-nitrates do not affect blood pressure and heart rate, thereby minimizing the side effects.

Non-nitrates antianginals are used along with other medications for treating ongoing angina (chronic angina). However, they should not be used in emergency cases (acute angina).

Non-nitrates antianginals can cause the following side effects:

• Nausea
• Constipation
• Headache
• Dizziness
• Dry mouth
• Blood in the urine
• Shortness of breath
• Ringing in the ears
• Blurred vision
• Vertigo
