How it works
Nifedipinehydrochlorothiazide
Nifedipine is a calcium channel blocker. It lowers blood pressure by slowing your heart rate and relaxing your blood vessels. Your heart gets more oxygen and doesn't have to work as hard to pump, which can relieve chest pain.Microzide (hydrochlorothiazide (HCTZ)) is a thiazide diuretic (water pill) that makes you urinate more. It works in the kidneys to remove extra water and certain electrolytes, while lowering blood pressure and reducing swelling.
