Treating Coronary Microvascular Angina

Nitroglycerin

Nitroglycerin capsules are designed to prevent pain in patients with coronary microvascular angina or traditional coronary disease. The medication is a member of a group of drugs called nitrates. Individuals with coronary microvascular angina experience chest pain when there isn't enough blood flow to the small arteries in the heart and nitroglycerin helps the blood vessels in the heart to relax and widen, allowing blood to flow more easily than it can with narrow, restrictive passages. The medication should be used to prevent chest pain, but it won't be helpful for relieving chest pain after it occurs. It's also important not to take it before engaging in physical activities. Patients should always talk to their doctor about the safest way to take the medication.
