Descrição detalhada
This study is a placebo controlled (2:1 drug vs. placebo), randomized clinical trial of 21 healthy, non-diabetic volunteers receiving daily doses of oral glyburide (1.5 mg) vs. placebo while under careful medical monitoring in an inpatient Clinical Research Unit (CRU)within the Center for Applied Research Sciences (CARS) at the Washington University in St. Louis Medical Center for a duration of 7 days and nights (24 hours per day). Interested subjects who call for more information about the study will be scheduled for a screening visit. Subjects will participate first in an informed consent process, and those wishing to take part will be asked to undergo a comprehensive interview detailing their past medical history and formal physical examination (which includes laboratory tests of the urine and blood). If a subject is deemed appropriate by the team, he/she will be asked to perform an exercise test (treadmill for 30 minutes) and will have an Electrocardiogram (ECG) completed to further determine eligibility. Individuals who do not meet inclusion criteria based on screening activities will be notified immediately that they are not eligible. Volunteers meeting all eligibility criteria will be scheduled for the week long in-patient evaluation.
Each subject will undergo a battery of physical, cognitive, and laboratory tests in addition to receiving oral glyburide or placebo each day for one week.

The primary objective of this study is to evaluate the safety of glyburide in healthy, non-diabetic volunteers while simulating strenuous activity to observe for any adverse events (i.e.
hypoglycemia, dizziness, confusion, etc.).
Neuropsychological testing, physical exams, vital signs, ECGs, cognitive assessments, and laboratory values (including serum glucose levels collected 4 x's per day and as needed) will be conducted throughout the 7 day in-patient study to assess for any adverse/serious adverse events.
