Brief summary
Human immunoglobulin (Ig) is the most commonly used blood product. It has been well-defined the efficacy in patients with immunodeficiencies, Kawasaki disease, asthma and other immune diseases. It is expected that Ig 10% will improve the usefulness and safety profile compared to Ig 5% because it is expected the reduced hospitalization/treatment duration and less adverse events related to volume overload.
Detailed description
GC5107A (IV-Globulin SN Inj. 10%) is a polyvalent intravenous human immunoglobulin G preparation. It is prepared from plasma collected from more than 1000 healthy blood donors and it expresses the large spectrum of antibody specificity.
Interventions
After GC5107A Intravenous injection, evaluate platelet increase
