Seizures early in life cause long-term behavioral modifications, namely long-term memory deficits in experimental animals. Since caffeine and adenosine A(2A) receptor (A(2A)R) antagonists prevent memory deficits in adult animals, we now investigated if they also prevented the long-term memory deficits

This model-based analysis quantifies the population pharmacokinetics (PK) of orally administered istradefylline, a selective adenosine A(2A) receptor antagonist, in healthy subjects and patients with Parkinson's disease, including the estimation of covariate effects on istradefylline PK parameters. Istradefylline plasma concentration data

Dopamine replacement therapy effectively treats the early motor symptoms of Parkinson's disease (PD). However, its association with the development of motor complications limits its usefulness in late stages of the disease. Adenosine A(2A) receptors are localised to the indirect striatal
