Rizatriptan for Episodic Dizziness in Vestibular Migraine


  • Study type

  • Study phase

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The purpose of this study is to look at the natural history of VM and learn more about common symptoms. Investigators also want to learn the effects, both positive and negative, of the commonly used migraine drug, rizatriptan, when it is used for spells of dizziness in people with VM.

Patients may be eligible to participate if:

  • Patients are between the ages of 18 & 65
  • Patients have a history of vestibular migraine
  • Patients are able to maintain a vestibular symptom diary

The study includes 3 visits with compensation. All participants must complete questionnaires on dizziness, headache symptoms, general health and well-being, mental health, and a questionnaire on patient's satisfaction with study medication.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
