High Blood Pressure Symptoms

Calcium channel blockers ( calcium antagonists )

There are three types of calcium antagonists. They all cause the arteries to relax, but some increase and others decrease the heart rate. Calcium channel blockers are most often used to treat high blood pressure in elderly people or in people of African-Caribbean origin. They can also be used to treat angina in people who cannot take beta-blockers.

Unwanted effects

Serious side effects are uncommon. Minor effects include flushing, headache, dizziness, swollen ankles, indigestion, feeling sick and vomiting.
