Recombinant human interferon α2b for injection (Pseudomonas)
Function and Efficacy
1. Pharmacokinetics The average serum concentration of Anfulong is the same after intramuscular and subcutaneous injection. The highest serum concentration is about 1.2-33.6 units/ml and occurs 1 to 24 hours later. The elimination half-life of Anfulong after intramuscular or subcutaneous injection is 4-12 hours, and its maximum blood concentration occurs 3.5-8 hours after administration. 2. Clinical studies Interferon α2b can make hepatitis B e antigen negative, normalize transaminase levels, reduce liver inflammation, and delay the progression to cirrhosis and improve the quality of life in 20%-30% of patients. Studies have shown that interferon α2b can normalize serum ALT, improve liver tissue and reduce the amount of virus in patients with chronic hepatitis C. Some other studies have also shown that interferon α2b has clinical significance in tumor regression or stabilization of hairy cell leukemia, and in the treatment of patients with Kaposi's sarcoma associated with AIDS. Interferon α2b is also very important for patients with chronic myeloid leukemia, and can also be used as an adjunct to intermittent treatment of Philadelphia chromosome-positive chronic myeloid leukemia.
