Feedback:
Calcium channel blockers are indicated for the treatment of Prinzmetal's angina because these drugs relieve coronary artery vasospasm, increasing blood flow to the muscle cells. Diltiazem is a calcium channel blocker. Beta-blockers are not indicated for the treatment of Prinzmetal's angina because they could cause vasospasm due to blocking of beta-receptor sites. Propranolol, nadolol, and metoprolol are beta-blockers.
