Purpose

Type 2 diabetes is a chronic condition that affects the ability of the body to regulate glucose (sugar). When glucose levels are low, the liver can make glucose to increase levels in the body. This important process is called endogenous glucose production (EGP). Previous studies suggest that the central nervous system (CNS), including the brain, helps to coordinate this process by communicating with the liver through potassium channels. Control of EGP can be impaired in people with type 2 diabetes, which may contribute to the high levels of glucose seen in these individuals. The purpose of this study is to understand how activating these potassium channels in the control centers of the brain with a medication called diazoxide might inhibit the amount of glucose made by the liver. This is particularly important for people with diabetes who have very high production of glucose, which in turn causes hyperglycemia (high levels of sugar in the blood) that leads to diabetes complications.

Detailed Description

In this study, the investigators will study healthy participants through a procedure called a "pancreatic clamp" study. During the clamp procedure, glucose (a sugar) and insulin (a hormone produced in the pancreas that regulates the amount of glucose in the blood) are infused with an intravenous catheter, and blood samples are collected periodically throughout the procedure to measure blood sugar levels and the levels of several hormones that are found in the body and are related to glucose metabolism. Endogenous glucose production (the production of sugar by the liver) will be measured in patients given diazoxide (a medication that activates potassium channels in the brain that may affect glucose production in the liver through brain-liver signaling), compared with when a placebo is given.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
