Study Notes
Calcium Channel Blockers
- Calcium channel blockers are medicines that lower blood pressure by blocking calcium from entering the cells of the heart and arteries.
- They work by relaxing and opening blood vessels, which reduces the force of the heart's contractions and eases blood flow.
- Calcium channel blockers can also slow the heart rate, further lowering blood pressure.
- Some calcium channel blockers may be prescribed to relieve chest pain (angina) and control irregular heartbeat.
- Calcium channel blockers are available in short-acting and long-acting forms.
- Short-acting medicines provide quick relief but their effects last for a few hours.
- Long-acting medicines are slowly released for a longer-lasting effect.
- Common examples of calcium channel blockers include Amlodipine, Diltiazem, Felodipine, Isradipine, Nicardipine, Nifedipine, Nisoldipine and Verapamil.

- They can also be used to prevent, treat or improve symptoms of various conditions, including coronary artery disease, angina, arrhythmia, and blood vessel conditions such as Raynaud's disease.
- For Black individuals, calcium channel blockers may be more effective than other blood pressure medications like beta blockers, ACE inhibitors, or angiotensin II receptor blockers.
Side Effects of Calcium Channel Blockers
