Possible Interaction: Dihydroxyphenylalanine and Gamma-Aminobutyric Acid

A single injection of L-DOPA enhanced GABA release in the medial globus pallidus on the lesioned side in L-DOPA-induced dyskinesia-model rats compared to Parkinson's disease-model rats.

GABA seems to inhibit tonically via GABA(A) receptors depressor responses to DOPA and to elicit pressor responses partially by inhibition of tonic function of endogenous DOPA to activate depressor sites in the NTS.
Prior DOPA ME (1 microg) inhibited by one-half pressor responses to 300 ng GABA.
Responses to DOPA (30 ng) were inhibited by pretreatment with GABA and nipecotic acid, but potentiated by bicuculline, when vascular responses to pretreated drugs returned to basal levels.

Moreover, the threonine phosphorylation of DARPP‐32 produced by maximally effective doses of either forskolin (in striatum) or l‐3,4‐dihydroxyphenylalanine (in substantia nigra) was increased further by GABA.
