The antinociceptive effect of vitamin K2 (menatetrenone) in mice was examined using tail-flick and formalin test. Menatetrenone at doses of 10, 50 and 100 mg/kg, i.p. produced a dose-dependent and significant inhibition of the tail-flick response in mice. Menatetrenone (50 and 100 mg/kg, i.p.) had no significant effect on the duration of the first phase of the formalin-induced flinching. However, menatetrenone (100 mg/kg, i.p.) significantly inhibited the second phase of the formalin-induced flinching. I.p. administration of menatetrenone (100 mg/kg) significantly reduced the duration of nociceptive responses induced by i.t. injection of bradykinin, but not of substance P, prostaglandin E2 or N-methyl-D-aspartate (NMDA). These present data suggest that i.p. pretreatment with menatetrenone produced dose-dependent antinociceptive effect in mice. This effect may be, at least in part, mediated by the inhibition of bradykinin dependent nociceptive transmission in the spinal cord.
