How do centrally acting antihypertensives work?

Centrally acting drugs work directly on the part of the brain that controls blood pressure. They soften the force of your heart beat and block nerve signals that can make your small blood vessels contract. This allows them to relax and widen, making it easier for blood to flow through, lowering your blood pressure.
