Usage

Description

(-)-R-Arotinolol is a chemical compound that belongs to the class of beta-adrenergic blocking agents. It is a stereoisomer of arotinolol, characterized by its specific three-dimensional arrangement of atoms. (-)-R-Arotinolol is known for its ability to block the action of adrenaline and noradrenaline on beta-adrenergic receptors, which contributes to its effectiveness in managing cardiovascular conditions.
Used in Pharmaceutical Industry:
(-)-R-Arotinolol is used as an antihypertensive agent for the treatment of high blood pressure. By blocking beta-adrenergic receptors, it helps to reduce the workload on the heart and lower blood pressure, thus contributing to cardiovascular health.
(-)-R-Arotinolol is used as an antianginal agent for the treatment of angina, a condition characterized by chest pain due to insufficient blood flow to the heart. Its action in blocking adrenaline and noradrenaline helps to alleviate the symptoms of angina.
(-)-R-Arotinolol is used as an antiarrhythmic agent for the treatment of arrhythmias, which are irregular heartbeats. Its ability to regulate the heart's function makes it effective in managing this condition and maintaining a regular heartbeat.

THERAPY FOR COMPLICATIONS OF DIABETES

A method for enhancing glycemic control and/or insulin sensitivity in a human subject having diabetic nephropathy and/or metabolic syndrome comprises administering to the subject a selective endothelin A (ETA) receptor antagonist in a glycemic control and/or insulin sensitivity enhancing effective amount. A method for treating a complex of comorbidities in an elderly diabetic human subject comprises administering to the subject a selective ETA receptor antagonist in combination or as adjunctive therapy with at least one additional agent that is (i) other than a selective ETA receptor antagonist and (ii) effective in treatment of diabetes and/or at least one of said comorbidities other than hypertension. A therapeutic combination useful in such a method comprises a selective ETA receptor antagonist and at least one antidiabetic, anti-obesity or antidyslipidemic agent other than a selective ETA receptor antagonist.
