What is Regadenoson and explain in detail?
Regadenoson, sold under the brand name Lexiscan among others, is an A2A adenosine receptor agonist that is a coronary vasodilator that is commonly used in pharmacologic stress testing. It produces hyperemia quickly and maintains it for a duration that is useful for radionuclide myocardial perfusion imaging. The selective nature of the drug makes it preferable to other stress agents such as adenosine, which are less selective and therefore cause more side-effects.
Regadenoson was approved by the United States Food and Drug Administration on April 10, 2008, and is marketed by Astellas Pharma under the tradename Lexiscan. It is approved for use in the European Union and under the name of Rapiscan. It is marketed by GE Healthcare and is sold in both the United Kingdom and Germany
