Long acting nitrates are taken 2-3 times per day and can be used to prevent angina. [6] Beta-blockers may also be used to reduce the incidence of chronic angina. [6] Beta-blockers prevent episodes of angina by reducing heart rate and reducing the strength of contraction of the heart, which lowers oxygen demand in the heart. [6]
The nitrates are used for the treatment and prevention of angina and acute myocardial infarction, while molsidomine acts too slowly to be useful for the treatment of acute angina. [2] For quick action in the treatment of angina, glyceryl trinitrate is used in form of a sublingual spray (nitro spray) or as soft capsules to be crunched.
Used to relieve both exertional and vasospastic angina by allowing venous pooling, reducing the pressure in the ventricles and so reducing wall tension and oxygen requirements in, the heart. Short-acting nitrates are used to abort angina attacks that have occurred, while longer-acting nitrates are used in the prophylactic management of the ...

Topical nifedipine has been shown to be as effective as topical nitrates for anal fissures. [18] Nifedipine is also used in high-altitude medicine to treat high altitude pulmonary edema. [19] Nifedipine is one of the main choices for the treatment of Prinzmetal angina due to its vasodilating effects on the coronary arteries. [2]
Nitroglycerin, also known as glyceryl trinitrate (GTN), is a vasodilator used for heart failure, high blood pressure (hypertension), anal fissures, painful periods, and to treat and prevent chest pain caused by decreased blood flow to the heart or due to the recreational use of cocaine.
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing , leg or feet swelling, and fatigue. [1] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of multiple organs by fluid ...
Dipyridamole is thus a pharmacological success diagnostically, but a therapeutic failure because of the coronary steal phenomenon. [ 4 ] Coronary steal is also the mechanism in most drug-based cardiac stress tests ; When a patient is incapable of doing physical activity they are given a vasodilator that produces a "cardiac steal syndrome" as a ...
