Pegylated Interferon Alpha 2B

Introduction

Pegylated Interferon Alpha 2B is a long-acting form of interferon used primarily to treat chronic viral infections and certain types of cancer. It is a modified version of interferon alpha-2b, where polyethylene glycol (PEG) is attached to improve its stability and effectiveness. This modification allows for less frequent dosing while maintaining a longer duration of action. Pegylated Interferon Alpha 2B helps to boost the immune system, enabling the body to fight infections and inhibit the growth of cancer cells.

Uses of Pegylated Interferon Alpha 2B

• Chronic Hepatitis C
• Chronic Hepatitis B
• Melanoma (skin cancer)
• Hairy Cell Leukemia
• Kaposi’s Sarcoma in HIV patients

How Pegylated Interferon Alpha 2B Works

Pegylated Interferon Alpha 2B works by stimulating the immune system to recognize and destroy infected or cancerous cells. It interferes with the replication of viruses and inhibits tumor growth by enhancing the activity of immune cells such as T-cells and natural killer cells. The PEGylation process prolongs its half-life, allowing sustained therapeutic effects with less frequent dosing.

Benefits of Pegylated Interferon Alpha 2B

• Longer duration of action, requiring fewer doses
• Effective in treating chronic hepatitis infections
• Helps slow the progression of certain cancers
• Boosts immune system function
• Convenient once-weekly injections
