Final answer:
The difference between selective and nonselective CCBs lies in their specificity for calcium channels in the body. Selective CCBs mainly target L-type calcium channels in cardiac and smooth muscle cells, while nonselective CCBs block both L-type and other types of calcium channels in various tissues. Selective CCBs like amlodipine are primarily used to treat hypertension, angina, and certain heart conditions, while nonselective CCBs like verapamil can also be used to treat cardiac arrhythmias.
Step-by-step explanation:
The difference between selective and nonselective CCBs lies in their specificity for calcium channels in the body.
Selective CCBs primarily target the L-type calcium channels found in cardiac and smooth muscle cells, while nonselective CCBs block both L-type and other types of calcium channels in various tissues.
For example, selective CCBs like amlodipine are commonly used to treat hypertension, angina, and certain heart conditions, while nonselective CCBs like verapamil are also used to treat cardiac arrhythmias.
