Context: This paper reports on the results of treatment of compressive neuralgia using a combination of nucleotides (uridine triphosphate trisodium [UTP] and cytidine monophosphate disodium [CMP]) and vitamin B-12.
Objectives: To assess the safety and efficacy of the combination of nucleotides (UTP and CMP) and vitamin B-12 in patients presenting with neuralgia arising from neural compression associated with degenerative orthopedic alterations and trauma, and to compare these effects with isolated administration of vitamin B-12.
Methods: A randomized, double-blind, controlled trial, consisting of a 30-day oral treatment period: Group A (n= 200) receiving nucleotides + vitamin B-12, and Group B (n= 200) receiving vitamin B-12 alone. The primary study endpoint was the percentage of subjects presenting pain visual analog scale (VAS) scores < 20 at end of study treatment period. Secondary study endpoints included the percentage of subjects presenting improvement > 5 points on the patient functionality questionnaire (PFQ); percentage of subjects presenting pain reduction (reduction in VAS scores at study end in relation to pretreatment); and number of subjects presenting adverse events.
Results: The results of this study showed a more expressive improvement in efficacy evaluations among subjects treated with the combination of nucleotides + vitamin B-12, with a statistically significant superiority of the combination in pain reduction (evidenced by VAS scores). There were adverse events in both treatment groups, but these were transitory and no severe adverse event was recorded during the study period. Safety parameters were maintained throughout the study in both treatment groups.
Conclusion: The combination of uridine, cytidine, and vitamin B-12 was safe and effective in the treatment of neuralgias arising from neural compression associated with degenerative orthopedic alterations and trauma.
