Wytensin is a brand name for the drug guanabenz. It is an antihypertensive medication used to lower high blood pressure. It acts centrally in the brain to reduce sympathetic outflow. Think of it like a central command center, dialing down the signals that cause blood vessels to constrict. Wytensin helps to relax blood vessels, resulting in lower blood pressure. It's similar to how a thermostat regulates temperature in a house.
