Official title
Dexmedetomidine Trial for Effects on Rhythms, Sleep Architecture, and Biomarker Dynamics - A Pilot Study (DEXTER)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The DEXTER study is a cross-over, double-blind, placebo-controlled pilot research study led by Dr. Peng Li. The goal of this project is to evaluate the safety, feasibility, and biological effects of a single dose of sublingual (under-the-tongue) dexmedetomidine (SL Dex) in older adults. Specifically, researchers want to see how this medication affects sleep patterns, internal 24-hour circadian rhythms, and the daily cycles of certain neurological proteins (specifically plasma p-tau217) associated with brain aging.
