    ..When A1Rs are present, actions of amitriptyline may, however, partly depend on A1Rs. ..

    ..Our results indicate that, while adenosine A(1) receptors are not required for oxcarbazepine to produce antinociception in knockout mice, such receptors are essential in order to see caffeine reversal of this antinociceptive effect. ..

    ..Therefore, increased extracellular adenosine levels in vivo appear to result partially from extracellular conversion of nucleotide and partially from inhibition of uptake. ..
