Nearly two years ago, I wrote about how the US Food and Drug Administration (FDA) appeared to be ready to approve a new drug for neurogenic orthostatic hypotension (NOH), which, basically, is a precipitous drop in blood pressure upon standing. (I recommend reading that blog as a good primer.) That drug, droxidopa with the brand name of Northera™, did not win approval because of outstanding concerns by FDA.

Dyskinesias are the twisting and writhing movements that occur as PD progresses – a common side effect of the medication levodopa (Sinemet®). Back in 2007, it was PDF-funded researcher Manolo Carta Ph.D., along with Anders Björklund, M.D., who performed the pre-clinical research that led to the identification of this drug. At the time, while many researchers were looking at dopamine neurons as the culprit behind dyskinesias (through their interaction with levodopa), Dr. Carta’s proposal suggested something… Read More

Chelsea recently received the recommendation of a FDA advisory committee to approve droxidopa as a treatment for neurogenic orthostatic hypotension or NOH for short. This recommendation was a big surprise since FDA documents released ahead of the committee meeting showed that agency staff members were clearly against approval; nevertheless, this approval recommendation will strongly influence the final decision expected to be made later this month. What is NOH? Normally, blood pressure increases as you… Read More
