Hydralazine is a medication that treats high blood pressure. It relaxes your blood vessels. This decreases your blood pressure and the amount of work your heart has to do.
It acts directly on arteriolar smooth muscle to cause relaxation. It decreases diastolic pressure by lowering peripheral vascular resistance. Due to preferential arteriolar dilatation, postural hypotension is uncommon. It increases heart rate and cardiac output.
