How Hydrochlorothiazide + S-amlodipine works
Hydrochlorothiazide, a diuretic also known as a "water pill", works by prompting the kidneys to remove extra salt and water from your body. This reduces fluid volume in your blood vessels, resulting in a decrease in blood pressure.
S-Amlodipine is a calcium channel blocker. It interferes with calcium's entry into the muscle cells of the heart and blood vessels. This results in relaxation and widening of blood vessels, which makes it easier for your heart to pump blood, thereby reducing blood pressure.
