Abstract: The present invention relates to an injection formulation composition for use as a filler or a drug carrier through a click chemistry reaction. More specifically, the present invention relates to an injection formulation composition comprising: a first liquid comprising a first biopolymer having a first click chemistry functional group introduced thereinto; and a second liquid comprising a second biopolymer having a second click chemistry functional group introduced thereinto, wherein the first click chemistry functional group is chemically linkable with the second click chemistry functional group, to a method for preparing an injection formulation hydrogel using the composition, and to a medical filler, an in-vivo injection type supporter, or a drug carrier using the composition.
