The disclosure concerns a method for the suppression of visceral pain by
regulating the T-type calcium channel; a visceral pain inhibitor that
includes a T-type calcium channel inhibitor as an effective ingredient;
and a method of screening a visceral pain inhibitor by investigating the
suppression activity of T-type calcium channels. Particularly, the
present invention relates to a method for the suppression of visceral
pain by regulating an alpha 1G T-type calcium channel in the central
nervous system and alpha 1H and alpha 1I T-type calcium channels in the
peripheral nervous system; a visceral pain inhibitor that includes a
T-type calcium channel inhibitor as an effective ingredient; and a method
of screening a visceral pain inhibitor by investigating the suppression
activity of T-type calcium channels. The method of the present invention
can be effectively used to suppress visceral pain by regulating T-type
calcium channel in a precise mechanism without any side effects.
