Calcium Channel Blockers Overview

✔ What are they?
Medications that relax blood vessels and reduce heart workload by preventing calcium from entering heart and blood vessel cells.

✔ How to recognize them?
Many end in "-dipine" (e.g., amlodipine, nifedipine, felodipine), but some like diltiazem and verapamil do not.

✔ How do they work?
Block calcium → Relax blood vessels → Lower blood pressure and heart strain.

✔ Easy trick to remember:
"Ca = Calm vessels, Calm heart"

✔ Common uses:

• High blood pressure

• Angina (chest pain)

• Irregular heartbeats (arrhythmias)

• Migraine prevention
