| E.1 Medical condition or disease under investigation |
| E.1.1 | Medical condition(s) being investigated |
| Hypertension and obstructive sleep apnea (OSA) |
|
| MedDRA Classification |
| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
To address if blood pressure response to Losartan is less adequate in hypertensive men with obstructive sleep apnea (OSA) compared to those without this state.
|
|
| E.2.2 | Secondary objectives of the trial |
To address if these groups differ from eachother in response to Losartan regarding the neuroendocrine hormones and cardiovascular biomarkers.
We will also address if treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP) has an additive effect regarding blood pressure response to Losartan in this group.

|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
-Men -Age 50-69 years -Body-Mass-Index <35 kg/m2 -Systolic Blood Pressures >=140 mmHg and/or Diastolic Blood Pressure >=95 mmHg -No known clinical disease except hypertension -No cardiovascular medication -Apnea-Hypopnea-Index (AHI) <5/h (no obstructive sleep apnea) or AHI>=15/h (obstructive sleep apnea) by sleep-recording -Written informed consent from the participant |
|
| E.4 | Principal exclusion criteria |
AHI 5-14.9/h by sleep-recording Manifest diabetes, liver- or kidney disease according to blood samples at screening Signs of atrial fibrillation or former myocardial infarction at electrocardiogram |
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
Blood-pressure response (ambulatory 24-h blood pressure) after 6 weeks of Losartan (50 mg) daily compared to baseline in patients with and without obstructive sleep apnea.
Blood-pressure response (ambulatory 24-h blood pressure) after another 6 week-period in subgroup of hypertensive patients with obstructive sleep apnea with "Losartan only" compared to the treatment with "Losartan and CPAP" |
