Brief Summary
Aliskiren (also called TekturnaTM) is a new drug for high blood pressure. Aliskiren works by blocking the actions of a substance called renin. Renin is a natural substance in the body that raises blood pressure. Renin is believed to contribute to the production of blood clots by increasing the amount of a substance known as Plasminogen Activator Inhibitor or PAI-1. This study will measure how aliskiren changes the amount of PAI-1 in the blood depending on the time of dosing. The purpose of this study is to find out if it is better to take aliskiren in the morning or at night.

Eligibility Criteria
You may qualify if:
- Adults 18-65 with hypertension
- Hypertension is defined as a systolic blood pressure at screening of ≥ 140, a diastolic blood pressure of ≥ 90, or a preexisting diagnosis of hypertension taking antihypertensive medication. If the subject is on anti-hypertensive medication, they can be included in the study, independent of the screening blood pressure.
You may not qualify if:
- Serum potassium \> 5.0 mmol/L (at the visit directly preceding Randomization)
- History of any cardiovascular event (stroke, TIA, MI, unstable angina, CABG, percutaneous coronary intervention, hospitalization due to HF) during the 3 months prior to Visit 1 or subsequent to enrollment.
- Malignant Hypertension (at Randomization): any patient with SBP \> 170 mmHg or DBP \> 120 mmHg
- Congestive heart failure NYHA class III and IV
- Unstable serum creatinine
- Second (II) or third (III) degree heart block without a pacemaker.
- Concurrent potentially life threatening arrhythmia or other uncontrolled arrhythmia.
- Clinically significant valvular heart disease.
- Known renal artery stenosis.
- Any surgical or medical condition which might significantly alter the absorption, distribution, metabolism, or excretion of the study drugs including, but not limited to, any of the following:
- History of major gastrointestinal tract surgery such as gastrectomy, gastroenterostomy, or bowel resection (patients with previous bariatric surgery \> 6 months prior to Visit 1 are allowed to participate).
- Any history of pancreatic injury, pancreatitis or evidence of impaired pancreatic function/injury as indicated by abnormal lipase or amylase.
- Evidence of hepatic disease as determined by any one of the following: SGPT value exceeding 3 x Upper Limit of Normal (ULN) at Visit 1, a history of hepatic encephalopathy, a history of cirrhosis, esophageal varices, or a history of portocaval shunt.
- History of malignancy other than basal cell skin cancer within the past five years.
- Any concurrent life threatening condition with a life expectancy less than 2 years.
