Treats high blood pressure. These prescriptions are prescribed to lower high blood pressure and work by relaxing blood
vessels. Angiotensin II is a chemical that the body releases to cause the constriction of blood vessels. Candesartan blocks
the action of angiotensin II, resulting in the relaxation of the blood vessels. This relaxation causes the blood pressure
to decrease. It takes about 2 weeks for Atacand to begin to the lower your blood pressure, and about 4 weeks for it to
reach its full effect. Your doctor may choose to use Atacand for other conditions. If you're unsure why you
are taking this prescription, contact your doctor.
