American Ginseng Overview

Ozanimod Hydrochloride Overview
-
Ozanimod is used to treat adults with relapsing forms of multiple sclerosis (MS; a disease in which the nerves do not function properly and people may experience weakness, numbness, loss of muscle coordination, and problems with vision, speech, and bladder control) including clinically isolated syndrome (CIS; nerve symptom episodes that last at least 24 hours), relapsing-remitting forms (course of disease where symptoms flare up from time to time), or secondary progressive forms (course of disease where relapses occur more often). It is also used to treat ulcerative colitis (a condition which causes swelling and sores in the lining of the colon [large intestine] and rectum) in adults. Ozanimod is in a class of medications called sphingosine l-phosphate receptor modulators. It works by decreasing the action of immune cells that may cause nerve damage.
