NCT04482985

Brief Summary

Motion sickness is a debilitating condition that can effect many crew members. Meclizine has long been known as an effective anti motion sickness drug. The response to the drug is variable - some are responders, while others are resistant to the drug. The aim of the present study is to examine whether there is a correlation between meclizine plasma levels and clinical response.

    ng/dl

    2 hours after meclizine administration

Study Arms (2)

Meclizine responders

ACTIVE COMPARATOR
Drug: Meclizine Hydrochloride
