Pharmacogenetics of Ace Inhibitor-Associated Angioedema
Completed · Not applicable · Has a placebo group
Conditions studied: Hypertension, Diabetes Type 2
In brief
The investigators would like to find out if sitagliptin (dipeptidyl peptidase-4 or DPP4 inhibition), a drug to treat diabetes, affects blood vessel relaxation in healthy people receiving enalapril (angiotensin converting enzyme or ACE inhibition), a blood pressure medicine. Understanding how these drugs interact in healthy people will help us learn their potential effects in people who have diabetes.
