A newly published study has found that an oral cannabinoid formulation was more effective than the prescription drug pregabalin in alleviating chronic neuropathic pain in an animal model, while also reducing inflammation and oxidative stress.

Researchers from Birla Institute of Technology and Science Pilani, Delhi Pharmaceutical Sciences & Research University, and the University of Delhi evaluated four cannabinoid formulations (F1 to F4) in a rat model of chronic sciatic nerve injury. The study, published in the journal Neurological Research, aimed to explore the therapeutic potential and mechanisms behind these formulations.
The 21-day study involved 35 male Wistar rats divided into seven groups. All groups except the control underwent a sciatic nerve ligation procedure to simulate chronic pain. The cannabinoid formulations, dissolved in MCT oil, were administered orally at varying concentrations (F1: 500 mg to F4: 3000 mg), with pregabalin serving as the reference drug.
