Dopamine agonists The chance that levodopa is normally neurotoxic, which the starting point of levodopa-induced problems may be linked to the length of time of treatment, will be the two most significant explanations why many professionals suggest delaying levodopa therapy until parkinsonian symptoms obviously begin to hinder sufferers functioning and regular lifestyle. (conferencedequebec.org)
To be able to hold off or prevent levodopa-induced problems many parkinsonologists recommend using DA agonists as the original or early type of dopaminergic therapy (Jankovic 2000). (conferencedequebec.org)

However, this mechanism cannot fully explain novel results indicating that dopaminergic neurons also mediate the aversive effects of cannabinoids in rodents, and previous results showing that preferentially presynaptic adenosine A2A receptor (A2AR) antagonists counteract self-administration of Δ-9-tetrahydrocannabinol (THC) in nonhuman primates (NHPs). (nih.gov)
Here, we review evidence supporting the involvement of cortical astrocytic CB1Rs in the activation of corticostriatal neurons and that A2AR receptor heteromers localized in striatal glutamatergic terminals mediate the counteracting effects of the presynaptic A2AR antagonists, constituting potential targets for the treatment of cannabinoid use disorder (CUD). (nih.gov)
It is generally assumed that the rewarding effects of cannabinoids are mediated by cannabinoid CB1 receptors (CB1Rs) the activation of which disinhibits dopaminergic neurons in the ventral tegmental area (VTA). (nih.gov)
