Official title
Renin System Responses to Combined Renin Inhibition and Beta Adrenergic Blockade
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Antihypertensive drug treatment is effective in only about 50% of patients. One mechanism responsible for treatment failure is a drug related stimulation of the renin-angiotension-aldosterone-system (RAAS). Several classes of medications that treat hypertension by blocking the RAAS system have been developed. However, the kidney responds to these drug treatments by producing greater amounts of renin. This high level of renin can reduce the effectiveness of some of these medications, ultimately causing the blood pressure to rise. This is one reason why blood pressure can be difficult to control in a certain percentage of patients. The hypothesis to be tested in the proposed study is that beta-adrenergic blockade (β-blockade), when superimposed upon aliskiren, a drug that competitively inhibits plasma renin activity (PRA) but stimulates the release of renin by the kidneys (plasma renin concentration \[PRC\]), can suppress the reactive increase in PRC that occurs during aliskiren monotherapy. The primary aim of this study is to measure plasma renin concentration (PRC) and plasma renin activity (PRA) levels during renin inhibition with aliskiren and combined renin inhibition/β-blocker treatment to determine whether the addition of a β-blocker attenuates the rise in plasma renin concentration (PRC). A secondary aim is to determine whether combined treatment further suppresses PRA and blood pressure.
