  • Look Inside

A rapid and excessive increase in extracellular dopamine (DA) after L-DOPA administration is con-sidered one of the major causes for L-DOPA-induced peak-dose dyskinesia. Therefore, inhibition of exces-sive rise in L-DOPA -derived DA is likely to be an ideal treatment for L-DOPA-induced dyskinesia Based on our previous experimental studies that 8- OH-DPAT, a potent 5-HT1A agonist, attenuates an in-crease in L-DOPA-induced extracellular DA in the striatum of the rat model of Parkinson's disease, we hypothesized that L-DOPA-induced dyskinesia in pa-tients with Parkinson's disease is alleviated by a 5- HT1A agonist.
