What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests if lamotrigine and bupropion can reduce vertigo attacks and dizziness in patients with Meniere's disease. These medications balance brain chemicals to help manage these symptoms. Lamotrigine is commonly used to prevent depressive relapses in bipolar disorder, while bupropion is an antidepressant with some evidence supporting its use in bipolar depression.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is the combination of Lamotrigine and Bupropion safe for humans?

Lamotrigine has been studied for safety in various conditions, showing it is generally well tolerated, though some people may experience side effects like dizziness, headache, or skin rash. Bupropion is not mentioned in the provided research, so specific safety data for the combination with Lamotrigine is not available.12345

How does the drug combination of Lamotrigine and Bupropion for Meniere's Disease differ from other treatments?

This treatment is unique because it combines Lamotrigine, a drug known for treating epilepsy and mood disorders, with Bupropion, an antidepressant, to address Meniere's Disease, a condition with no standard treatment. This novel approach leverages the individual benefits of these drugs, potentially offering a new way to manage symptoms.12567

What Are the Treatments Tested in This Trial?

Interventions

  • Lamotrigine and Bupropion
  • Placebo
Trial Overview The trial is testing if Lamotrigine and Bupropion reduce vertigo attacks better than a placebo in Meniere's disease patients. It's a double-blind study where participants won't know if they're getting the real treatment or a placebo for about 9 months.

Published Research Related to This Trial

Lamotrigine (LTG) was found to have a similar safety profile to placebo in a pooled analysis of four double-blind trials involving 92 patients, with only two patients withdrawing due to adverse effects.
In a larger group of 572 patients from open studies, common side effects included dizziness and headache, but no significant clinical changes or serious adverse events were linked to LTG, indicating it is generally safe when added to existing antiepileptic treatments.
Human safety of lamotrigine.Betts, T., Goodwin, G., Withers, RM., et al.[2019]
Lamotrigine is an effective and well-tolerated treatment for bipolar disorder, particularly beneficial for managing depressive symptoms during both acute and maintenance phases, as supported by various placebo-controlled studies involving different patient types.
Unlike traditional antidepressants, lamotrigine does not trigger manic episodes or increase cycling frequency, making it a preferred option for treating acute bipolar depression and preventing recurrent depressive symptoms.
