ADENOSINE (Adenocard®)
Drug Classification:
- Antidysrhythmic (Class V)

Adenosine (A1) R-agonist ⇒ Slows AV conduction by activation of G-protein second messengers, decreasing cAMP and inhibiting calcium entry into the
pacemaker cells

Drug-Drug Interaction
* Methylxanthines (i.e. caffeine) are nonspecific competitive antagonists for adenosine receptors **double** the dose for Pt.’s taking large amounts* * Carbamazepines (i.e. Tegretol, Phenobarbitol) potentiate effects of adenosine –**halve** the dose*
