Pharmacodynamics
Regadenoson rapidly increases coronary blood flow (CBF) which is sustained for a short duration. Mean average peak velocity increased to greater than twice baseline by 30 seconds and decreased to less than twice the baseline level within 10 minutes. Myocardial uptake of the radiopharmaceutical is proportional to (CBF). Regadenoson increases blood flow in normal coronary arteries but not in stenotic (blocked) arteries. The significance of this finding is that stenotic arteries will take up less of the radiopharmaceutical than normal coronary arteries, resulting in a signal that is less intense in these areas.
Mechanism of Action
Regadenoson is an selective low-affinity (Ki= 1.3 µM) A2A receptor agonist that mimics the effects of adenosine in causing coronary vasodilatation and increasing myocardial blood flow. It is a very weak agonist of the A1 adenosine receptor (Ki > 16.5 µM). Furthermore, it has negligible affinity to A2B and A3 adenosine receptors. Regadenoson is undergoing trials for use in pharmacological stress tests. Adenosine slows conduction time through the A-V node, can interrupt the reentry pathways through the A-V node, and can restore normal sinus rhythm in patients with paroxysmal supraventricular tachycardia (PSVT), including PSVT associated with Wolff-Parkinson-White Syndrome.

Absorption, Distribution and Excretion
The pharmacokinetic profile of regadenoson is best described by a 3-compartment model. T max, injection = 1 to 3 minutes; Onset of pharmacodynamic response = 1 to 3 minutes; E max 12.3 ng/mL
58% of total regadenoson eliminate is via renal excretion
Central compartment: 11.5 L; Steady state: 78.7 L
Average plasma renal clearance = 450 mL/min. As this value is larger than the glomerular filtration rate, this suggests occurrence of renal tubular secretion.
Applications
DescriptionLexiscan ™(regadenoson) is an injectable adenosine A2A receptor agonist for use as a pharmacologic stress agent in myocardial perfusion imaging (MPI) studies in patients unable to undergo adequate exercise induced stress. Regadenoson is the first adenosine A2A receptor agonist shown to be safe and effective as a pharmacologic stress agent in MPI studies. It is delivered as a rapid bolus (approximately 10 seconds) with no dose adjustment required for body weight. The product was developed under a license and collaboration agreement between CV Therapeutics and Astellas, and was launched by Astellas in June of 2008.
UsesA selective A2A adenosine receptor agonist in myocardial imaging
UsesRegadenoson is a selective, short-acting adenosine A2A receptor agonist (Ki = 1.1 nM for pig striatum A2A receptor). It increases coronary blood flow 3.4- to 3.8-fold with a half-time to reversal of 1.9-2.6 minutes in open-chest anesthetized pigs. Regadenoson is used to induce hyperemia (increased blood flow), particularly in the context of myocardial perfusion imaging. It has also been found to increase the delivery of compounds to the central nervous system through the blood-brain barrier in animals.
UsesRegadenoson is a selective and potent A2A adenosine receptor agonist (1). The adenosine A2A receptor is a G-protein-coupled receptor and a key therapeutic target for oncologic, inflammatory, Parkinson''s and cardiovascular diseases (2). In rodent studies, it has been shown that co-administration of Regadenoson with Temozolomide (T017775) can increase Temozolomide concentration in the brain (3).
