Beneficial effects of the phytocannabinoid Δ9-THCV in L-DOPA-induced dyskinesia in Parkinson’s disease.

Neurobiology of Disease“The antioxidant and CB2 receptor agonist properties of Δ9-tetrahydrocannabivarin (Δ9-THCV) afforded neuroprotection in experimental Parkinson’s disease (PD), whereas its CB1 receptor antagonist profile at doses lower than 5 mg/kg caused anti-hypokinetic effects.

In the present study, we investigated the anti-dyskinetic potential of Δ9-THCV (administered i.p. at 2 mg/kg for two weeks), which had not been investigated before.

In summary, our data support the anti-dyskinetic potential of Δ9-THCV, both to delay the occurrence and to attenuate the magnitude of dyskinetic signs. Although further studies are clearly required to determine the clinical significance of these data in humans, the results nevertheless situate Δ9-THCV in a promising position for developing a cannabinoid-based therapy for patients with PD.”

“Δ9-THCV exhibited anti-dyskinetic properties in L-DOPA-treated Pitx3ak mutant mice. It delayed the onset of dyskinetic signs and reduced their neurochemical changes. It also reduced their intensity when given once dyskinesia was already present. This potential adds to other properties of Δ9-THCV as antiparkinsonian therapy.

In summary, our data support the anti-dyskinetic potential of Δ9-THCV to ameliorate adverse effects caused by L-DOPA, in particular delaying the occurrence and attenuating the magnitude of dyskinetic signs. This adds to its promising symptom-alleviating and neuroprotective properties described previously. Although further studies are clearly required to determine the clinical significance of these data in humans, the results nevertheless situate Δ9-THCV in a promising position for developing a cannabinoid-based therapy for PD patients.”
