摘要
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.
用白話說明這項交互作用的意義
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.
為什麼會發生
Competitive antagonism of adenosine A2A receptors by caffeine opposing the agonist action of regadenoson.
處置方式
Withhold caffeine and other methylxanthines (coffee, tea, cola, theophylline) for at least 12 hours before the stress test, or per local protocol. Reschedule the test if recent intake is confirmed.
