The active substance of Gilenya is fingolimod. Gilenya can alter the way the body's immune system works and is used to treat relapsing remitting multiple sclerosis (MS) and relapses in patients with secondary progressive multiple sclerosis. Gilenya slows down the progression of physical disability and decreases the number of flare-ups (relapses) in patients with some relapsing forms of MS. Gilenya helps to fight against attacks of the immune system by affecting the ability of some white blood cells to move freely within the body and by stopping the cells that cause inflammation from reaching the brain. This reduces nerve damage caused by MS. Gilenya may also have a direct and beneficial effect on certain brain cells (neural cells) involved in repairing or slowing down the damage of MS.

1 GILENYA ® FINGOLIMOD NAME OF THE MEDICINE The active ingredient of GILENYA is fingolimod. Chemical name: 2-amino-2-(2-(4-octylphenyl)ethyl]propan-1,3-diol hydrochloride Chemical structure: N H 2 OH OH Cl H . Molecular formula: C 19 H 33 NO 2 · HCl CAS number: 162359-56-0 Molecular weight: 343.93 DESCRIPTION Fingolimod hydrochloride is a white to almost white crystalline powder which is freely soluble in water. Fingolimod is a base with pKa of 7.82. Therefore, it has high solubility at low pH and very low solubility at high pH (e.g. < 0.01 mg/mL at pH 6.8). Relevant distribution coefficients are 22.3 in n-Octanol/water and 1290 in n-Octanol/hydrochloric acid 0.1N. Each GILENYA capsule contains 0.56 mg fingolimod hydrochloride (equivalent to 0.5 mg fingolimod), mannitol, magnesium stearate, titanium dioxide and gelatin. PHARMACOLOGY MECHANISM OF ACTION Fingolimod is a sphingosine 1-phosphate receptor modulator. Fingolimod is metabolized by sphingosine kinase to the active metabolite fingolimod-phosphate. Fingolimod-phosphate, binds at low nanomolar concentrations to sphingosine 1-phosphate (S1P) receptors 1, 3, and 4 located on lymphocytes, and readily crosses the blood brain barrier to bind to S1P receptors 1, 3, and 5 located on neural cells in the central nervous system. By acting as a functional antagonist of S1P receptors on lymphocytes, fingolimod-phosphate blocks the capacity of lymphocytes to egress from lymph nodes, causing a redistribution, rather than depletion, of lymphocytes. This redistribution reduces the infiltration of pathogenic lymphocyte cells into the central nervous system where they would be involved in nerve inflammation and nervous tissue damage. Animal studies and _in vitro_ experiments indicate that fingolimod may also exert beneficial effects in Aqra d-dokument sħiħ
