CCB’s work by reducing the amount of calcium entering heart cells and blood vessel walls. This allows blood vessels to relax and the heart to receive more oxygenated blood. Some CCB’s block calcium going into conducting cells in the heart and so slow heart rate. CCB’s are commonly prescribed to treat hypertension, angina and some abnormal heart rhythms.
Side Effects:
Common side effects include hypotension (low blood pressure), facial flushing, palpitations, headaches, ankle swelling and constipation. There are alternate medications if you experience any side effects from CCB’s.
