Nighttime Dosing of Antihypertensive Drugs in Type 2 Diabetes
Summary
The purpose of this study is to investigate if it is possible to lower the nighttime blood pressure in patients with type 2 diabetes mellitus by shifting the administration of antihypertensive drugs from morning to nighttime.
Description
In recent years several studies have shown that high nighttime blood pressure is associated with increased cardiovascular risk independently of the average 24 hour blood pressure. As a consequence there has been increasing focus on nighttime blood pressure and how to lower it. One way of addressing the problem is to shift the administration of antihypertensive drugs from morning to nighttime. Studies on non-diabetic patients show that by doing this the nighttime blood pressure can be lowered with 3-5 mm Hg without negative effect on the 24 hour blood pressure.
Only recently a study was made on diabetic patients. This showed similar results as for non-diabetic patients.However this study was based on diabetic patients who did not receive any antihypertensive drugs before.
This study will investigate the effects on nighttime blood pressure when shifting administration of antihypertensive drugs from morning to nighttime. The population is diabetic patients who are already in antihypertensive treatment.

Medical and Biotech [MESH] Definitions
Prediabetic State
The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).
Diabetes Mellitus, Type 2
A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.
Diabetes Mellitus, Experimental
Diabetes mellitus induced experimentally by administration of various diabetogenic agents or by PANCREATECTOMY.
Diabetes Mellitus, Type 1
A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
Diabetes Mellitus, Lipoatrophic
A type of diabetes mellitus that is characterized by severe INSULIN RESISTANCE and LIPODYSTROPHY. The latter may be generalized, partial, acquired, or congenital (LIPODYSTROPHY, CONGENITAL GENERALIZED).
