He explains that while it's approved for major depressive disorder and may improve cognitive dysfunction associated with depression, there's no strong evidence supporting its use in treatment-resistant depression or other conditions. Rossi also highlights the medication's mechanism of action, dosing, side effects, and potential drug interactions, emphasizing its moderate effect size compared to other antidepressants.

Takeaways

• 👨‍⚕️ Dr. Rossi discusses Trintellix (vortioxetine), a newer antidepressant medication, providing an overview of its uses and effects.
• 🔍 Trintellix is approved in the U.S. for major depressive disorder, with off-label uses having limited evidence, such as generalized anxiety disorder.
• 🌐 The medication's name was changed to Trintellix in the U.S. to avoid confusion with another medication, Brelanta, used for cardiovascular disease.
• 💊 Trintellix is considered a serotonin modulator and stimulator, working through various mechanisms including serotonin reuptake inhibition and receptor modulation.
• 🧠 It shows potential in improving cognitive dysfunction associated with depression, particularly in geriatric patients, but not in dementia or neurocognitive disorders.
• 🛑 The drug manufacturer discontinued trials for ADHD after failing to show adequate benefit.
• 💡 The most robust actions of Trintellix are serotonin reuptake inhibition and 5HT3 receptor antagonism, which are key to its mechanism of action.
• ⏱ Trintellix has a half-life of 66 hours, allowing for once-daily dosing, with common doses ranging from 5 to 20 milligrams per day.
• 📉 No specific lab tests are required before starting the medication, but basic labs are generally recommended for all patients.
• 🤢 Common side effects include nausea, vomiting, constipation, sexual dysfunction, and potentially weight gain, with nausea being the most prevalent.
• ⚠️ Rare but serious side effects to watch for include seizure induction, mania, and suicidal thoughts, especially in patients under 24 years old.

Q & A

What is Trintellix or Vortioxetine?

Trintellix, also known as Vortioxetine, is a newer type of antidepressant medication approved in the U.S. for major depressive disorder. It has been studied for other conditions such as generalized anxiety disorder, but its primary indication remains major depressive disorder.

Why was the name changed to Trintellix in the U.S.?

The name was changed to Trintellix in the U.S. to avoid confusion with another medication called Brelanta, which is used for cardiovascular disease and has a similar name.

What is the role of Vortioxetine in treating Generalized Anxiety Disorder (GAD)?

While Vortioxetine has been studied for GAD, the quality of evidence is poor, and it does not appear to significantly improve symptoms or quality of life in patients with GAD.

How does Vortioxetine compare to other antidepressants in terms of effectiveness?

According to the research literature, Vortioxetine does not perform better than other antidepressants overall. However, individual responses may vary, and some patients might respond better to this medication than others.

What is unique about Vortioxetine's potential for cognitive enhancement?

Vortioxetine may improve cognitive dysfunction associated with depression, which includes poor concentration, focus, and memory. It also appears to improve cognitive function in geriatric depression, but it has not shown benefits in cognitive function for patients with Alzheimer's disease or in ADHD.

How does Vortioxetine work as a serotonin modulator and stimulator?

Vortioxetine works by several mechanisms, including serotonin reuptake inhibition, partial agonism at 5HT1A and 5HT1B receptors, antagonism at 5HT3 receptors, and antagonism at 5HT7 receptors. These actions contribute to its antidepressant and potential cognitive-enhancing effects.

Which cytochrome P450 enzymes are involved in the metabolism of Vortioxetine?

Vortioxetine is metabolized by multiple cytochrome P450 enzymes, with the most significant being CYP2D6, followed by 3A4, 2C19, 2C9, 2A6, and others.

What is the half-life of Vortioxetine, and how does it affect dosing?

The half-life of Vortioxetine is 66 hours, which allows for once-daily dosing. The typical doses range from 5 to 20 milligrams per day, with the initial dose for depression being 10 milligrams per day.

Are there any specific lab tests required before starting Vortioxetine?

There are no specific lab tests required before starting Vortioxetine for healthy individuals. However, it is generally a good practice to obtain basic labs before starting any new medication.

What are the common side effects associated with Vortioxetine?

Common side effects of Vortioxetine include nausea, vomiting, constipation, sexual dysfunction, and possibly weight gain. Sexual dysfunction was noted to occur even in the placebo group during clinical trials.

What are the rare but serious side effects that should be considered with Vortioxetine?

Rare but serious side effects of Vortioxetine include the potential to induce seizures, mania, or suicidal thoughts, especially in patients under the age of 24. It should not be combined with MAOIs due to the risk of serotonin syndrome.
