Description
Emsam is a brand name for transdermal selegiline, a treatment for Parkinson’s disease and major depressive disorder. Emsam is available as a patch that should be pasted onto the skin like an adhesive bandage.
Drug Information
Emsam’s active ingredient is a monoamine oxidase inhibitor (MAOI) called selegiline. MAOIs inhibit the activity of enzymes in the monoamine oxidase family, and have historically been considered a last line of treatment in cases where tricyclic antidepressants and Selective Serotonin Reuptake Inhibitors (SSRIs) have failed. Newer MAOIs like selegiline, which is a phenethylamine, however are considered safe for initial treatments.
Selegiline is mainly used to treat Parkinson’s disease because it enhances the effects L-DOPA chemicals that act against the disease. Emsam is the first transdermal patch containing selegiline as a treatment for major depression. The transdermal patch constitutes of three layers: an outer backing layer, an adhesive layer and a release liner that touches the skin. The adhesive patch delivers the drug through the skin into the bloodstream.
Emsam transdermal patches are available in 6, 9 or 12 milligram doses.
Due to Selegiline being chemically similar to certain illicit drugs, it is a controlled substance in Japan that can only be obtained with a special prescription or a government issued license.
Selegiline is not a government controlled substance in the United States, but requires a physician’s prescription to obtain from a pharmacy.
