Effects of a nutraceutical combination in patients with chronic lumbosacral radicular pain.

Drugs used for the treatment of chronic lumbosacral radicular pain (LRP) may have frequent adverse effects leading to medication withdrawal. The use of add-on nutraceuticals, which have no side effects, may therefore play a role in LRP treatment. We performed a six-week, single-center, open label prospective uncontrolled clinical study to evaluate the effect of a nutraceutical combination (Noxiall®) used as an add-on therapy in patients with chronic LRP. Fifteen patients were treated with Noxiall® twice a day for 10 consecutive days, followed by once-daily administration up to the end of the six-week treatment. The participants were evaluated at two visits (before-after), when primary and secondary outcomes were assessed. We found a significant reduction in pain severity post-treatment, as assessed using a numerical rating scale (p= 0.03), and a significant reduction in painkiller intake (p=0.03). Nutraceuticals could be a complementary therapy for chronic LRP.
