概要
Caffeine and other methylxanthines block adenosine receptors, which is how regadenoson produces coronary vasodilation. Recent caffeine intake can blunt the vasodilator response and lead to a false-negative or less reliable myocardial perfusion stress test.
この相互作用をわかりやすく説明すると
Caffeine and Regadenoson can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Caffeine belongs to Miscellaneous; Regadenoson belongs to Cardiovascular.
なぜ起こるのか
Competitive antagonism of adenosine A2A receptors by caffeine opposing the agonist action of regadenoson.
対処法
