This can cause symptoms such as headaches and dizziness. KEY POINTS AND PRACTICAL RECOMMENDATIONS: Calcium channel blockers, which dilate arteries by reducing calcium flux into cells, effectively lower blood pressure, especially in combination with other drugs, and some formulations of agents of this class are approved for treating angina or cardiac dysrhythmias.
