Rate of motor response to oral levodopa and the clinical progression of Parkinson's disease.

Abstract:

:We investigated the relationship between the rate of motor response after a standard levodopa oral dose and drug dynamic variables and disease-related factors in 66 patients with Parkinson's disease. Time to maximum finger tapping effect was positively correlated with matched duration of levodopa dose response and fell from a median 120 minutes in patients at Hoehn and Yahr stage I and II to 60 minutes in stage IV patients (p < 0.001). The accelerated response to levodopa dose with the advancement of disease was also apparent as an increased steepness of the tapping effect versus time curve, with a shift from a hyperbolic to a sigmoid profile. The rate of motor response to oral levodopa may reflect the rate of dopamine interaction with the postsynaptic receptors, providing an indirect objective index of presynaptic dopaminergic homeostasis.
