Safinamide is recently approved by the FDA for the treatment of Parkinson’s disease as an add-on therapy to levodopa-carbidopa
- Treatment of Parkinson’s disease with levodopa/ carbidopa is characterized by “on” and “off” periods
- Safinamide could help the patients during the “off” periods
- Its side effects and contraindications should be understood before prescribing the drug
Side effects of safinamide include high blood pressure, involuntary movements, falls, nausea, sleep disturbances including insomnia or excessive sleep, and eye problems. Behavioral symptoms include problems with impulse control/compulsive behaviors, confusion, hallucinations and psychotic behavior. High fever may occur on stopping the drug. It can cause a dangerous condition called serotonin syndrome when used with certain other medications like MAOIs, antidepressants, opioid drugs, or cyclobenzaprine.
Safinamide should not be prescribed in patients with severe liver disease. It should also not be taken with medications like dextromethorphan, monoamine oxidase inhibitors (MAOI), certain antidepressants, St. John’s Wort and opioid drugs.
The new drug brings hope to the numerous people in the United States who experience fluctuations in symptoms with the conventional treatment for Parkinson’s disease.
