Epoxy steroidal aldosterone antagonist and beta-adrenergic antagonist combination therapy for treatment of congestive heart failure

摘要

A combination therapy comprising a therapeutically-effective amount of an epoxy-steroidal aldosterone receptor antagonist and a therapeutically-effective amount of a beta-adrenergic antagonist is described for treatment of circulatory disorders, including cardiovascular disorders such as hypertension, congestive heart failure, cirrhosis and ascites. Preferred beta-adrenergic antagonists are those compounds having high potency and bioavailability. Preferred epoxy-steroidal aldosterone receptor antagonists are 20-spiroxane steroidal compounds characterized by the presence of a 9alpha,11alpha-substituted epoxy moiety. A preferred combination therapy includes the beta-adrenergic antagonist metoprolol ((±)1-(isopropylamino)-3-[p-(2-methoxyethyl)phenoxyl]-2-propanolol succinate) and the aldosterone receptor antagonist epoxymexrenone.
