Summary

This trial is testing a medication called tradipitant to see if it can help people who get sick when they travel. The study includes both men and women who experience motion sickness. Tradipitant works by stopping the brain from sending signals that cause nausea and vomiting. Tradipitant has the potential to be an effective therapy for the prevention of vomiting and treatment of nausea in people with motion sickness.

Who is the study for?
This trial is for adults aged 18-75 who have a history of getting motion sickness. It's not suitable for individuals with other nausea-causing conditions, those with a BMI over 40, or anyone allergic to Neurokinin-1 Receptor antagonists.
What is being tested?
The study is testing the safety and effectiveness of Tradipitant in preventing or reducing symptoms of motion sickness during travel. This open label trial allows all participants to receive the medication.
What are the potential side effects?
Potential side effects may include drowsiness, dry mouth, headache, and possible gastrointestinal issues like constipation. Since it's an open label study, more side effects might be identified as participants report them.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Tradipitant, an NK1 receptor antagonist, works by blocking the action of substance P, a neuropeptide involved in vomiting and nausea pathways. Common treatments for motion sickness include antihistamines (e.g., dimenhydrinate) that block H1 receptors to reduce vestibular system activity, and anticholinergics (e.g., scopolamine) that inhibit muscarinic receptors to prevent nausea signals from reaching the brain. Understanding these mechanisms is crucial for patients as it helps in selecting the most effective treatment based on their specific symptoms and potential side effects, ensuring better management of motion sickness.
