Hyperinsulinemic glucose clamp with Xanax given orally at beginning of each 2 hour clamp on day 1.
1 mg alprazolam given orally 60 minutes prior to each 2 hour glucose clamp on day 1 (x2)
Other Name: Xanax
Hyperinsulinemic glucose clamp in group with no drug.
Other: control group
control group is two hyperinsulinemic glucose clamps on day 1 with no drug given.
Due to the fundamental importance of glucose as a cerebral fuel, a complex and redundant counterregulatory response to hypoglycemia exists in man. Some studies have shown that prior activation of GABA(A) receptors may result in blunting of counterregulatory responses during next day hypoglycemia.
The Specific Aim is to determine if repeated activation of GABA(A) receptors using Alprazolam will result in blunting of neuroendocrine, ANS and metabolic counterregulatory mechanisms during next day hypoglycemia in T1DM and healthy man.
