title: Antinociceptive properties of thiamine, pyridoxine and cyanocobalamin following repeated oral administration to mice.
abstract: Following repeated oral administration for 7 days thiamine (thiamine nitrate, CAS 532-43-4), pyridoxine (pyridoxol hydrochloride, CAS 58-56-0), and cyanocobalamin (CAS 68-19-9) exhibited at high dose levels alone or in combination dose-related antinociceptive properties in the writhing test in the mouse. Cyanocobalamin exerted a potentiating effect in the combination of the 3 vitamins.
