THC and gabapentin interactions in a mouse neuropathic pain model

Add to Mendeley

Highlights

We examined interactions between tetrahydrocannabiniol (THC) and gabapentin in a mouse neuropathic pain model.

THC and gabapentin synergistically reduced allodynia.

Coadministration with gabapentin increased the therapeutic window of THC.

Thus, THC may provide an adjuvant to current neuropathic pain medications.

Abstract

Clinical studies have shown that the major psychoactive ingredient of Cannabis sativa Δ9-tetrahydrocannabinol (THC) has some analgesic efficacy in neuropathic pain states. However, THC has a significant side effect profile. We examined whether the profile of THC could be improved by co-administering it with the first-line neuropathic pain medication gabapentin. This was done using the chronic constriction injury (CCI) model of neuropathic pain in C57BL6 mice. At 8 days post-CCI nerve injury, acute systemic administration of gabapentin produced a dose-dependent decrease in CCI-induced mechanical and cold allodynia, and increased motor incoordination. Coadministration of THC and gabapentin in a fixed-ratio dose-dependently reduced mechanical and cold allodynia, and produced all the side-effects observed for THC, including motor incoordination, catalepsy and sedation. Isobolographic analysis indicated that the ED50 for the THC:gabapentin induced reduction in allodynia was 1.7 times less than that predicted for an additive interaction. The therapeutic window of combination THC:gabapentin was greater than that for THC alone. These findings indicate that gabapentin synergistically enhances the anti-allodynic actions of THC and improves its therapeutic window. Thus, THC may represent a potential adjuvant for neuropathic pain medications such as gabapentin.
