Final answer:
The two non-dihydropyridine calcium channel blockers are diltiazem and verapamil, which are used to treat cardiovascular conditions by blocking calcium channels, leading to vasodilation and decreased heart rate.
Step-by-step explanation:
The two non-dihydropyridine calcium channel blockers (CCBs) are diltiazem (Cardizem, Tiazac) and verapamil (Calan, Verelan). These medications are used to treat hypertension, angina, and certain heart arrhythmias by blocking calcium channels in the heart and blood vessels, leading to relaxation and dilation of the blood vessels. Unlike dihydropyridine calcium channel blockers, non-dihydropyridines also decrease the heart rate and can be used to control abnormal heart rhythms.
