Composition comprising immunoglobulin

摘要

Liquid compositions for intravenous administration that comprise an aqueous solution of immunoglobulin and methods of preparing such compositions are disclosed. The solution has a pH in the range of 5.0 to 5.8 and an ionic strength is the range 0.02 to 0.25. The liquid compositions are formulated so as to be stable upon storage such that the immunoglobulin does not substantially aggregate nor degrade and maintains acceptable levels of anti-complementary activity, PKA activity and kallikrein activity during storage for an extended period at a temperature in the range of 4° C. to 25° C.
