Can a simple eye test predict which seasickness pill works best for you?
NCT ID NCT03270839
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how two common seasickness drugs (scopolamine and meclizine) change inner ear balance tests in 54 healthy soldiers who get seasick. Researchers measured eye movements before and after taking the drugs to see if these tests could predict which drug works best for each person. The goal is to help doctors choose the right motion sickness medicine more easily.
