Fingolimod (Gilenya): The Newest Medication For Multiple Sclerosis
Multiple sclerosis (MS) is an autoimmune disease in which cells of your immune system attack nerve cells of the brain and spinal cord. This attack by your immune system damages a fatty substance called myelin that coats the nerve cells and acts as insulation to insure efficient transmission of nerve signals from one cell to another. Medications used for multiple sclerosis, including Gilenya, are called disease-modifying drugs because they alter the course of MS and slow its progression by suppressing or altering the activity of your immune system. Although they do not cure MS, these drugs can improve the quality of your life.
Information on Fingolimod (Gilenya)
Gilenya was approved as a treatment for the relapsing form of multiple sclerosis by the U.S. Food and Drug Administration in September 2010. People with relapsing MS suffer clearly defined attacks (called relapses) of degrading neurological function followed by periods of partial or complete recovery. People with MS were excited to hear of Gilenya's approval because it is a once-a-day oral medication. Previous MS drugs were administered intravenously. According to Drugs.com, Gilenya traps immune cells inside the lymph nodes. The trapped cells are not able to attack the nerve cells of the brain and spinal cord, and so the patient suffers relapses less frequently.
In clinical trials before it came to market, Gilenya demonstated efficacy over both placebo and interferon beta-1a, an older MS drug. In the trial versus placebo, 70% of patients receiving Gilenya experienced no relapse compared to 46% of patients on placebo. In the trial versus interferon beta-1a, 83% of patients on Gilenya did not have a relapse whereas only 70% on interferon beta-1a had no relapse.
When the FDA approved Gilenya for marketing, it also recommended that patients taking their first dose should do so under medical supervision. This is because the first dose of Gilenya may cause bradycardia, a condition in which your heart rate slows down to a level that is below normal. Typically, you will get your first dose in a hospital where your heart rate can be monitored for around six hours after you take the drug. Symptoms of a slow heart rate include dizziness, fatigue and heart palpitations. According to an FDA Drug Safety Communication, your heart rate should return to normal within one month after you start taking Gilenya.
Besides bradycardia, Gilenya may cause other side effects. The most frequently occurring of these are headache, influenza, diarrhea, back pain, elevation of liver enzymes and cough. Other side effects may include hypertension, blurred vision, eye pain and macular edema, a swelling in the center of the retina.
