Olmvesso

Olmvesso is a pharmaceutical medication primarily used for the treatment of relapsing forms of multiple sclerosis (MS) in adults. It is a disease-modifying therapy (DMT) designed to reduce the frequency of clinical relapses and slow the accumulation of disability. The active ingredient in Olmvesso is siponimod, which is an oral selective sphingosine-1-phosphate (S1P) receptor modulator.

Siponimod works by binding to S1P receptors on lymphocytes, a type of white blood cell. This binding prevents the lymphocytes from migrating from lymph nodes into the central nervous system (CNS). In multiple sclerosis, an overactive immune system attacks the myelin sheath that protects nerve fibers in the brain and spinal cord, leading to inflammation and nerve damage. By reducing the number of lymphocytes in the CNS, siponimod helps to decrease this inflammatory process.

Olmvesso is taken orally once daily. Before starting treatment, patients undergo specific genetic testing to determine their CYP2C9 genotype, as this can affect how the drug is metabolized. Dosage adjustments may be necessary based on this testing. The medication is typically initiated with a titration period to allow the body to adjust to the drug and minimize potential side effects such as slow heart rate. Common side effects can include infections, hair loss, and changes in liver function. It is important for individuals taking Olmvesso to be monitored regularly by their healthcare provider.
