OBJECTIVE: To review the literature concerning the physiology of the endocannabinoid system, current drug development of cannabinoid agonists, and current clinical research on the use of cannabinoid agonists for analgesia.

DATA SOURCES:Articles were identified through a search of MEDLINE (1966-August 2005) using the key words cannabis, cannabinoid, cannabi*, cannabidiol, nabilone, THC, pain, and analgesia. No search limits were included. Additional references were located through review of the bibliographies of the articles identified.

STUDY SELECTION AND DATA EXTRACTION:Studies of cannabinoid agonists for treatment of pain were selected and were not limited by pain type or etiology. Studies or reviews using animal models of pain were also included. Articles that related to the physiology and pharmacology of the endocannabinoid system were evaluated.

DATA SYNTHESIS:The discovery of cannabinoid receptors and endogenous ligands for these receptors has led to increased drug development of cannabinoid agonists. New cannabimimetic agents have been associated with fewer systemic adverse effects than delta-9-tetrahydrocannabinol, including recent development of cannabis medicinal extracts for sublingual use (approved in Canada), and have had promising results for analgesia in initial human trials. Several synthetic cannabinoids have also been studied in humans, including 2 cannabinoid agonists available on the international market.

CONCLUSIONS:Cannabinoids provide a potential approach to pain management with a novel therapeutic target and mechanism. Chronic pain often requires a polypharmaceutical approach to management, and cannabinoids are a potential addition to the arsenal of treatment options.

Background: Multiple sclerosis (MS) is the most chronic and inflammatory disorder. Because of limited efficacy and adverse side effects, identifying novel therapeutic and protective agents is important. This study was aimed to assess the potential therapeutic effects of hemp seed and evening primrose oils as well as Hot-nature dietary intervention on RRMS patients.

METHODS AND MATERIALS:

In this double blind, randomized trial, 100 MS patients with EDSS<6 were allocated into 3 groups: "Group A" who received co-supplemented hemp seed and evening primrose oils with advised Hot-nature diet, "Group B" who received olive oil, "Group C" who received the co-supplemented oils. Mizadj, clinically EDSS and relapse rate as well as immunological factors (IL-4, IFN-γ and IL-17) were assessed at baseline and after 6 months.

RESULTS:

Mean follow-up was 180±2.9 SD days (N=65, 23 M and 42 F aged 34.25±8.07 years with disease duration 6.80±4.33 years). There was no significant difference in studies parameters at baseline. After 6 months, significant improvements in Mizadj, EDSS and relapse rate were found in the groups A and C, while the group B showed a border significant decrease in relapse rate. Immunological parameters showed improvement in groups A and C, whereas there was worsening condition for group B after the intervention.

CONCLUSION:

The co-supplemented hemp seed and evening primrose oils with Hot-nature diet have beneficial effects in improving of clinical score in RRMS patients which were confirmed by immunological findings.
