Hydralazine

Definition

Hydralazine is a medication primarily used to treat high blood pressure by relaxing blood vessels, allowing blood to flow more easily. It can have significant effects on the neurological system due to its impact on blood pressure and circulation.

5 Must Know Facts For Your Next Test

1. Hydralazine's primary effect is vasodilation, which lowers blood pressure and improves blood flow.
2. It can be particularly useful in managing hypertensive emergencies, including those affecting the brain.
3. Side effects of hydralazine may include headache, dizziness, and reflex tachycardia due to its potent vasodilatory effects.
4. Proper nutrition and hydration can influence the effectiveness and side effects of hydralazine therapy.
5. Monitoring neurological symptoms is crucial when a patient starts hydralazine, as changes in blood pressure can impact cerebral perfusion.
