Guanabenz is a medication used to treat high blood pressure. It works by stimulating alpha-adrenergic receptors in the brain, which reduces sympathetic outflow and lowers blood pressure. Think of it like a dimmer switch for your nervous system's 'fight or flight' response, specifically targeting the signals that raise blood pressure. Unlike some blood pressure meds, guanabenz can sometimes cause drowsiness. It's similar to how a thermostat controls temperature, but guanabenz controls blood pressure.
