Northera and Dizziness

Monday April 28, 2014

The FDA has approved a new medicine that can help dizziness associated with Parkinson’s disease. Referred to as Droxidopa in clinical trials, this new drug called Northera is for neurogenic orthostatic hypotension (NOH).

Blood pressure is controlled by circulation changes tightly regulated by the nervous system. These neurologic reflexes allow pressure to stay constant, avoiding drops caused by gravity with body changes. This insures a steady blood flow to the organs and brain. When blood pressure drops with changes in body position, blood flow to the brain is reduced since a certain pressure is needed for blood to flow against gravity from heart to brain.
