Why is this medication prescribed?

Hydralazine is prescribed for the treatment of high blood pressure (hypertension) and certain heart conditions, such as congestive heart failure. It is classified as a vasodilator, which means it works by relaxing and widening the blood vessels, allowing blood to flow more easily.

When prescribed for hypertension, hydralazine is often used in combination with other medications to help lower blood pressure. It may be prescribed when other antihypertensive medications have not been effective or are contraindicated.
