Antianginal Medications to Treat Heart Attack and Coronary Heart Disease

Antianginal medications are drugs used to prevent or relieve angina, a condition in which chest pain or discomfort occurs due to inadequate blood flow to the heart. They work by dilating the blood vessels, increasing blood flow to the heart, or reducing the heart’s oxygen demand. Here are some commonly used antianginal medications:

1. Nitrates: Nitrates are the most commonly used antianginal medications. They work by dilating the blood vessels, increasing blood flow to the heart, and reducing the heart’s oxygen demand. Nitroglycerin is a commonly used nitrate that comes in various forms, such as tablets, patches, sprays, and ointments.
2. Beta-blockers: Beta-blockers work by reducing the heart’s oxygen demand and the workload on the heart. They also help to dilate the blood vessels, which increases blood flow to the heart. Some commonly used beta-blockers include metoprolol, atenolol, and propranolol.
3. Calcium channel blockers: Calcium channel blockers work by dilating the blood vessels and reducing the heart’s workload. They also help to reduce the heart’s oxygen demand. Some commonly used calcium channel blockers include amlodipine, diltiazem, and verapamil.
4. Ranolazine: Ranolazine is a newer medication used to treat chronic angina. It works by blocking the late sodium current in the heart cells, which reduces the heart’s oxygen demand.

It’s important to note that these medications can have side effects, and their use should be supervised by a healthcare professional. Additionally, some individuals may require a combination of medications to effectively manage their angina symptoms.
