[Analgesic activity of Benexol-B12 in the painful vertebral syndrome].

In order to verify the analgesic activity of an association of vitamin B1 - B6 - B12 (Benexol B12) in the painful vertebral syndrome, the Authors have performed a comparative trial between 20 patients treated with the association and 20 patients treated with a brain phospholipid extract (Cronassial). The results obtained in the two groups of patients are discussed.
