XADAGO, with its active ingredient safinamide, is a prescription medication used in the treatment of Parkinson's disease. It belongs to a class of drugs known as MAO-B inhibitors, which work by increasing the levels of certain chemicals in the brain that help improve the symptoms of Parkinson's disease, such as tremors, stiffness, and slowed movement. XADAGO is specifically approved for use as an add-on treatment to levodopa/carbidopa when these medications do not provide adequate symptom control. It is available in tablet form and is taken orally. As with any medication, it is important to use XADAGO under the guidance of a healthcare professional, who can provide information on the correct dosage and potential side effects.
