The investigators have recently discovered a genetic variant in an adrenergic receptor that leads to increased risk for type 2 diabetes. The investigators have also seen that blockers of that receptor improves impaired insulin secretion in animals. The investigators will now test the blocker in patients with type 2 diabetes with or without the risk variant in an effort to make diabetes treatment more individualized.
We have recently discovered a genetic variant in an adrenergic receptor that leads to increased risk for type 2 diabetes. We have also seen that blockers of that receptor improves impaired insulin secretion in animals. We will now test the blocker in patients with type 2 diabetes with or without the risk variant in an effort to make diabetes treatment more individualized. Patients will receive two different doses of the blocker and the effect will be measured with oral glucose tolerance tests. The study is a randomized placebo-controlled study.

Yohimbine capsule
Skanes Universitetssjukhus
Malmö, Skåne County, Sweden
Insulin Secretion
insulin secretion will be measured (nMole) in response to an oral glucose tolerance test. Patients will receive the capsules 1 h before the glucose test, and the insulin levels 30 minutes after the oral glucose will be used as a primary outcome measure. The insulin levels at the highest tolerated dose of yohimbine will be used.
Time frame: 30 minutes after oral glucose
Glucose
Plasma glucose will be measure (mMole) in response to an oral glucose tolerance test. Patients will receive the capsules 1 h before the glucose test, and the glucose levels 30 minutes after the oral glucose will be used as a secondary outcome measure. The glucose levels at the highest tolerated dose of yohimbine will be used.
Time frame: 30 minutes after oral glucose
