Emerging drugs for the acute treatment of relapses in adult neuromyelitis optica spectrum disorder patients

NMOSD relapses require prompt evaluation and timely treatment to restore function and mitigate disability. Timing is critical. Plasmapheresis showed better outcomes in terms of recovery when compared to high-dose intravenous methylprednisolone alone. Some groups suggest that plasmapheresis could be considered as an initial treatment approach in different clinical scenarios due to its higher effectiveness. Future research and/or real-world data will establish the advantages and disadvantages of these new treatments and define the appropriate patient profile.
