Quizplus · Accepted Answer

Calcium channel blockers are commonly used to treat angina caused by spasms of the coronary arteries. These drugs work by relaxing smooth muscle cells in the walls of blood vessels, which can relieve the spasm and increase blood flow to the heart. Nitroglycerides and beta blockers are also used to treat angina, but they work in different ways and are not specifically targeted toward spasms of the coronary arteries. Antihypertensives may be prescribed if a patient with angina also has high blood pressure, but they are not typically used solely to treat angina caused by spasms of the coronary arteries.
