Zusammenfassung
Aldosteron und dem Aldosteronrezeptor können neben Effekten auf den Elektrolyt- und Wasserhaushalt weitere Rollen in der Pathophysiologie kardiovaskulärer Erkrankungen zugeschrieben werden. Diese Effekte betreffen z. B. Blutdruck (durch direkte Aldosteroneffekte auf Gefäße und ZNS), Hypertrophie und Remodeling. Mit Spironolacton und Eplerenon stehen 2 Aldosteronrezeptorantagonisten für den Dauergebrauch zur Verfügung, die ihre klinische Wirksamkeit in endpunktbasierten Studien gezeigt haben. Spironolacton hat zusätzlich zur antagonistischen Wirkung am Mineralokortikoidrezeptor Wirkungen am Testosteron- und Progesteronrezeptor, die zu endokrinen Nebenwirkungen führen können. Entsprechende UAW fehlen bei Eplerenon, das als selektiver Aldosteronrezeptorantagonist klassifiziert werden kann. Eplerenon hat eine kürzere Plasmahalbwertszeit als die aktiven Metabolite von Spironolacton. Eplerenon wird durch CYP3A4 metabolisiert, hier müssen pharmakokinetische Interaktionen bedacht werden. Wesentlich bei der Kombination von Aldosteronrezeptorantagonisten mit anderen prognoseverbessernden Substanzen in der Herzinsuffizienztherapie ist die Kontrolle der Kaliumspiegel und der Nierenfunktion. Die Dosierungsempfehlungen sollten unbedingt beachtet werden. Besonderer Aufmerksamkeit hinsichtlich der Entwicklung einer Hyperkaliämie bedürfen Patienten mit Einschränkung der Nierenfunktion. Aldosteronantagonisten sollten bei einer glomerulären Filtrationsrate unter 50 ml/min nicht eingesetzt werden.
Abstract
In addition to the classical effects exerted by aldosterone on water and electrolyte haemostasis, recent data suggest additional roles in the pathophysiology of cardiovascular diseases. Examples are the regulation of blood pressure (by direct aldosterone effects on vessels and the CNS), myocardial hypertrophy and remodelling. Two aldosterone receptor antagonists, spironolactone and eplerenone, are currently available for the long-term therapy of chronic heart failure. Both compounds have clearly demonstrated their efficacy in heart failure treatment in end-point based clinical trials. Spironolactone, in addition to its antagonistic effects on the mineralocorticoid receptor, has anti-androgenic and gestagenic actions which can lead to endocrine side effects. Eplerenone selectively blocks aldosterone receptors and thus lacks adverse effects caused by non-specific steroid receptor blockade. The elimination half-life of eplerenone is shorter than the half-life of the active metabolites of spironolactone. Eplerenone is metabolised by CYP3A4, and pharmacokinetic interactions with inhibitors and inducers of this enzyme have to be considered. Essential for the clinical use of aldosterone antagonists in heart failure is the careful monitoring of potassium levels and renal function. The recommended doses should be followed precisely. Higher doses increase the risk of developing life-threatening hyperkalemia. Particular attention has to be paid to patients with impaired renal function. Aldosterone receptor antagonists should not be used when the glomerular filtration rate is below 50 ml/min.
