Altace, Approved by the FDA in 1991, Altace is commonly prescribed to treat high blood pressure (hypertension) and to reduce the risk of heart attack, stroke, and cardiovascular death. As an ACE inhibitor, Altace works by relaxing blood vessels, allowing blood to flow more easily and the heart to pump more efficiently. Available in capsule form, it is typically taken once daily. Patients using Altace should adhere strictly to their prescribed dosage and consult their healthcare provider regularly to monitor for any potential side effects or interactions with other medications.
