Anti anginal drugs

6.8 Antianginal – Nitrates Open Resources for Nursing (Open RN) Antianginal medication is used to treat angina pectoris. Angina is chest pain caused by inadequate blood flow, resulting in hypoxia of the cardiac tissue. Angina can be chronic pain caused by atherosclerosis in coronary artery disease or acute pain caused by a myocardial infarction. Antianginals increase blood flow to the heart or decrease oxygen demand by the heart. Nitrates promote vasodilation of coronary arteries and veins. Beta blockers and calcium channel blockers are also used to decrease workload of the heart and decrease oxygen demands. Nitrates may come in a variety of routes, such as sublingual, extended-release tablets, creams, transdermal patches, and intravenously. The grid below focuses on administration via sublingual tablets. Sublingual tablets are prescribed PRN (“as needed”) for patients who are experiencing chronic, stable angina due to coronary artery disease. Mechanism of Action Nitroglycerin relieves angina by relaxing vascular smooth muscle, resulting in vasodilation. Indications for Use Nitroglycerin is used to relieve angina due to coronary artery disease, during times of an acute attack, or prophylactically. Nursing Considerations Across the Lifespan Patients taking sildenafil (Viagra) or similiar medications for erectile dysfunction in the previous 24 hours may not take nitroglycerin as this may result in a dangerous drop in blood pressure. Nitroglycerin should not be used in pr...

Antianginal agents is a term used to describe a wide variety of medicines that are used in the management of Examples of antianginal agents include: • Nitrates (eg, isosorbide dinitrate, isosorbide mononitrate, nitroglycerin). These relax smooth muscle within the blood vessels, widening them and making it easier for blood and oxygen to reach the heart • Calcium antagonists (eg, diltiazem, nifedipine, nimodipine, verapamil). These inhibit calcium transfer into cells thereby inhibiting contraction of vascular smooth muscle • Beta blockers (eg, atenolol, pindolol, propranolol, metoprolol). These slow the heart, reducing how hard it has to work • Ranolazine. The exact way it exerts its antianginal effect is not known but may be through inhibition of ion channels during cardiac repolarization.

Exertional Angina: In patients with exertional angina, NORVASC reduces the total peripheral resistance (afterload) against which the heart works and reduces the rate pressure product, and thus myocardial oxygen demand, at any given level of exercise.

Angina pectoris is the medical term for chest pain or discomfort due to coronary heart disease. Angina is a symptom of a condition called myocardial ischemia. It occurs when the heart muscle (myocardium) doesn't get as much blood (hence as much oxygen) as it needs. This usually happens because one or more of the heart's arteries (blood vessels that supply blood to the heart muscle) is narrowed or blocked. Insufficient blood supply is called ischemia. Typical angina is uncomfortable pressure, fullness, squeezing or pain in the center of the chest. The discomfort also may be felt in the neck, jaw, shoulder, back or arm. Many types of chest discomfort aren't related to angina. Acid reflux (heartburn) and lung infection or inflammation are examples.
