Study design: In an open, multicentric observational study involving 234 doctors in private practice, the evolution of symptoms and the tolerability of a vitamin B preparation (Neurotrat forte) used as treatment in 1,149 patients with polyneuropathy, neuralgia, radiculopathy and neuritis associated with pain and paresthesias, were observed. The form of administration (ampoules, dragées), dosage and duration of treatment were left to the individual care-providing physician. The target symptoms evaluated were intensity of pain, muscle weakness affecting the legs, and paresthesia.
Results: Under treatment, there was a clear improvement in these symptoms. At a second examination approximately three weeks after initiation of treatment, a positive effect on pain in particular was observed in 69% of the cases. Similar observations were also made for paresthesias and muscular weakness in the legs.
