Trastuzumab Injection – 150mg / 440mg | HER2+ Breast Cancer Treatment

🔬 What is Trastuzumab?

Trastuzumab is a targeted monoclonal antibody that specifically binds to the HER2/neu receptor, slowing or stopping the growth of HER2-positive cancer cells. It is primarily used in:

• HER2-positive breast cancer (early and metastatic)

• HER2-overexpressing gastric cancer

Trastuzumab improves survival and decreases recurrence when used alone or alongside chemotherapy.

💊 Available Strengths:

• Trastuzumab 150mg single-use vial (lyophilized powder for injection)

• Trastuzumab 440mg multi-use vial (with bacteriostatic water for injection)

Available from trusted manufacturers like Roche (Herceptin), Mylan (Ogivri), Reliance Life Sciences (TrastuRel), and Biocon (Canmab).

✅ Key Benefits:

• Targets HER2+ cells without harming healthy ones

• FDA & WHO-approved therapy

• Often used with paclitaxel, docetaxel, or pertuzumab

• Proven to extend survival in metastatic HER2+ cancer

🧬 How Trastuzumab Works:

Trastuzumab works by binding to HER2 receptors on the surface of cancer cells, blocking signals that cause cells to grow. It also activates the immune system to destroy the cancer cells through antibody-dependent cellular cytotoxicity (ADCC).
