The generic name for the transdermal drug approved to treat major depressive disorder in adults is selegiline. It is delivered through a skin patch, offering a unique alternative to oral antidepressants.
Selegiline is an effective antidepressant from an older class of drugs known as MAOIs. Its delivery as a transdermal patch is a key feature designed to reduce certain risks, but it still requires significant caution and strict adherence to dietary and medication guidelines.
How Selegiline Works
An MAOI Antidepressant
Selegiline belongs to a class of antidepressants called monoamine oxidase inhibitors (MAOIs). These were among the first types of antidepressants developed.
They work by blocking the action of an enzyme called monoamine oxidase.
The Role of the MAO Enzyme
The monoamine oxidase enzyme is responsible for breaking down neurotransmitters in the brain, such as serotonin, norepinephrine, and dopamine. These chemicals are crucial for regulating mood.
By inhibiting this enzyme, selegiline increases the levels of these key neurotransmitters, which can help alleviate symptoms of depression.
The Significance of the Transdermal Patch
Bypassing the Digestive System
The selegiline patch, marketed under the brand name Emsam, delivers the medication directly through the skin into the bloodstream.
This transdermal delivery is a critical feature. It bypasses the stomach and liver, which changes how the drug is processed by the body.
Potentially Reducing Dietary Restrictions
Oral MAOIs are famous for requiring a strict diet low in tyramine, a compound found in aged cheeses, cured meats, and other fermented foods.
When MAO is inhibited in the gut, high levels of tyramine can cause a dangerous spike in blood pressure known as a hypertensive crisis.
Because the selegiline patch bypasses the gut, the risk of this interaction is reduced, especially at the lowest dose. However, dietary restrictions are still recommended, particularly at higher doses of the patch.
Understanding the Trade-offs and Risks
The Tyramine Effect
Despite the patch's design, the risk of a hypertensive crisis from consuming high-tyramine foods is not eliminated. Patients must be fully aware of which foods to avoid.
This reaction is severe and can be life-threatening, causing a sudden, extreme increase in blood pressure.
Serotonin Syndrome
Like other antidepressants, selegiline carries a risk of serotonin syndrome if combined with other medications that increase serotonin.
This includes common antidepressants like SSRIs (e.g., Prozac, Zoloft) and SNRIs (e.g., Effexor, Cymbalta), as well as certain pain relievers and migraine medications. A "washout" period is required when switching to or from an MAOI.
Common Side Effects
The most common side effect is an application site reaction, such as redness or irritation where the patch is worn.
Other potential side effects include insomnia, headache, and diarrhea.
Making the Right Choice for Your Goal
Deciding on an antidepressant requires a careful discussion of risks and benefits with a qualified healthcare provider.
- If your primary focus is treatment-resistant depression: MAOIs like selegiline are often considered highly effective options when other, newer classes of antidepressants have failed.
- If your primary focus is avoiding oral pills: The transdermal patch provides a clear and effective alternative for medication delivery.
- If your primary focus is minimizing lifestyle changes: Selegiline may not be the ideal first choice, as it requires more vigilance regarding diet and medication interactions than most other antidepressants.
Ultimately, understanding how selegiline works empowers you to have a more informed conversation with your doctor about your treatment path.
