5. The composition according to claim 1 , wherein said compound is lactose.
6. The composition according to claim 1 , which contains 0.4 to 50 parts by weight of said compound(s) with respect to one part by weight of the cyclic polypeptide compound or its pharmaceutically acceptable salt.
7. The composition according to claim 1 , which contains 0.1 to 400 mg of the cyclic polypeptide compound or its pharmaceutically acceptable salt in a single unit dose.
8. The composition according to claim 1 prepared by:
dissolving the cyclic polypeptide compound (I) or its pharmaceutically acceptable salt, the said compound(s), and optionally a pH adjustor, in a purified water and
lyophilizing the solution.
9. The composition of claim 1 which when dissolved in purified water, gives a solution of pH 4.0 to 7.5.
10. The composition of claim 1 which contains 3.4% or less by weight of water.
11. A method for preparing a stabilized pharmaceutical composition comprising:
dissolving a cyclic polypeptide compound of the general formula (I):
wherein R 1 is a hydrogen atom or an acyl group and R 2 and R 3 are, the same or different, a hydrogen atom or a hydroxyl group, or its pharmaceutically acceptable salt and
one or more compounds selected from the group consisting of a polysaccharide, a disaccharide and sodium chloride in water, and optional a pH adjustor, and
lyophilizing the solution.
12. An injection preparation prepared by dissolving the composition of claim 1 in isotonic sodium chloride solution.
