Resumo
The effects of some B vitamins on chemical nociception in mice or paw edema in rats were investigated. A combination of thiamine (B1), pyridoxine (B6) and cyanocobalamin (B12), in doses of 100,100 and 5mg/kg, i.p., respectively, potentiated the inhibition by diclofenac or thalidomide of paw edema induced by carrageenin in rat. Antinociceptive effects of diclofenac and thalidomide inhibition of abdominal contortion were also potentiated by the combination of the vitamins B1, B6 and B12. Thiamine, pyridoxine and cyanocobalamin given singly were effective in potentiating antinociceptive effects of thalidomide, but only cyanocobalamin potentiated these effects of diclofenac, probably reflecting the differing mechanisms of action of the two drugs. The results document the positive influence of B vitamins on antinociceptive effects of diclofenac or thalidomide and support the use of B vitamins to shorten the treatment time and reduce the daily dose of anti-inflammatories.
