Abstract

[Problem] To provide a composition for hemostasis that can be applied uniformly to a bleeding site and exerts a high hemostatic effect. [Solution] Provided is a composition to be applied to the subject as a spray, wherein the composition is characterized in that the spray is for hemostasis, and the composition includes a self-assembling peptide, the self-assembling peptide gelling due to self-assembly when the composition is applied to the bleeding site of the subject, and the self-assembling peptide being included in the composition in a concentration having an improved hemostatic capacity in comparison to direct application.

Claims (9)

1. A method for hemostasis in a subject, comprising the step of

applying a composition comprising a self-assembling peptide to a bleeding site of the subject by spraying the composition on the bleeding site at a pressure of 0.5 to 1.5 kgf/cm2, wherein

the self-assembling peptide self-assembles and thereby gels when the composition is applied to the bleeding site of the subject,

the self-assembling peptide is a peptide comprising IEIKIEIKIEIKI (SEQ ID NO: 2), and

the concentration of the self-assembling peptide in the composition is 1.5% to 3% by weight.

2. The method according to claim 1 , wherein

the bleeding site of the subject is a non-surgically formed wound site or a surgically formed incision site or excision site.

3. The method according to claim 1 , wherein

the subject is a nonhuman animal.
