Phenoxybenzamine works by blocking the action of certain natural substances in the body, specifically adrenaline and noradrenaline, which are responsible for increasing blood pressure by constricting blood vessels. By blocking these substances, phenoxybenzamine causes blood vessels to dilate, leading to a decrease in blood pressure.
