Vitamins of the B group have long been used to treat neuropathies of different origins and the accompanying pain. A combination of the vitamins B(1), B(6), and B(12) prevents the slowing of impulse conduction produced by tetanic stimulation in diabetic mice. In patients suffering from diabetic neuropathy, B vitamins alleviate pain in the upper extremities. ⋯ It has recently also been reported that a combination of the vitamins B1, B6, and B12 has analgesic properties in non-neuropathic conditions. In animal experiments, B vitamins diminish nociceptive responses in spinal and thalamic neurones and potentiate the antinociceptive effect of analgesic agents. Similarly, B vitamins potentiate the therapeutic effect of diclofenac in patients suffering from acute low back pain.

In the Federal Republic of Germany, strict regulations complicate the prescription of strong opioids to patients suffering from severe pain. In summer 1991 the German Association for the Study of Pain launched an initiative directed at simplification of the prescription requirements for such analgesics and submitted the suggestions to the ministries responsible. ⋯ Moreover, the prescriptions are to be simpler to make out and certain exemptions have been specified by law. Acceptance of the bill by the political committees and its realization are expected in autumn 1992.
