Antianginal drugs are used primarily to restore the balance between the oxygen supply and demand of the heart. These drugs dilate the coronary vessels to increase the flow of oxygen to the ischemic regions. Other than that, they also decrease the workload of the heart so the organ would have less demand for oxygen. Learn about antianginal drugs, nitrates, beta-blockers, and calcium channel blockers in this simplified guide for nursing pharmacology. Show
Antianginal Drugs: Generic and Brand Names
Disease spotlight: Coronary Artery DiseaseCoronary Artery Disease (CAD) is the narrowing of blood vessels supplying oxygen and nutrients to the heart, primarily due to the development of fatty tumors (atheromas) in the lumen of blood vessels in a process called atherosclerosis.

Practice Quiz: Antianginal DrugsQuiz time! Take our 5-item quiz about antianginal agents! 1. Type of angina which involves spasm of the blood vessels A. Stable angina 2. Contraction and relaxation in each cardiac cycle is controlled by: A. autonomic nervous system 3. All of the following can cause arrhythmia, except: A. acidosis 4. Verapamil and diltiazem belong to which class of antiarrhythmics? A. Class IV 5. The conduction system of the heart include the following: A. Sinoatrial node 1. Answer: D. Prinzmetal angina. It is an unusual type of angina that involves the spasm of blood vessels and not just by narrowing of vessels. Person with prinzmetal angina has angina at rest and associated ECG changes. 2. Answer: B. the heart. Contraction and relaxation is controlled by impulses arising spontaneously in the SA node and transmitted via a specialized conducting system to activate all parts of the muscle almost simultaneously. These rhythmic and continuous contractions are controlled by the heart itself. 3. Answer: D. None of the above. Electrolyte disturbances, hypoxic conditions, acidosis or accumulation of waste products, and structural damage of the conduction system can lead to arrhythmia. 4. Answer: A. Class IV. Verapamil and diltiazem are calcium-channel blockers and belong to Class IV antiarrhythmics. 5. Answer: A. Sinoatrial node. Path of conduction is as follows: SA node -> AV node -> Bundle of His -> Purkinje fibers. Recommended ResourcesRecommended resources and reference books. Disclosure: Includes Amazon affiliate links.

What are the adverse effects of nitrates?WHAT ARE SIDE EFFECTS OF NITRATES?. Headache.. Dizziness.. Nausea.. Lightheadedness.. Restlessness.. Stomach discomfort.. Skin rash.. Dry mouth.. What should you assess after giving nitroglycerin?Assess blood pressure periodically and compare to normal values (See Appendix F). Report low blood pressure (hypotension), especially if patient experiences dizziness, fainting, or other symptoms. Assess heart rate, ECG, and heart sounds, especially during exercise (See Appendices G, H).
Which is the most common side effect from nitrates?The most common side effects of nitrates include headaches, dizziness or light-headedness, flushing or a warm feeling in the face.
What are the symptoms associated with nitrates?What are the side effects?. Dizziness.. Headaches.. Flushing of your face and neck.. Upset stomach or throwing up.. Low blood pressure (hypotension). Irregular heart rhythms (arrhythmia). |
