Trastuzumab

Trastuzumab is a targeted therapy drug used to treat HER2-positive breast and gastric cancer. It is a monoclonal antibody that specifically targets the HER2 protein, which promotes cancer cell growth. By blocking HER2, Trastuzumab helps slow the progression of cancer and improves survival rates. This medicine is often used alone or in combination with chemotherapy to enhance treatment effectiveness. Available as an intravenous injection, it is administered under medical supervision in a hospital or clinical setting.

Uses of Trastuzumab

• Treatment of HER2-positive breast cancer
• Management of HER2-positive metastatic gastric cancer
• Prevention of cancer recurrence after surgery
• Used in combination with chemotherapy for better outcomes

How Trastuzumab Works

Trastuzumab works by targeting the HER2 receptor, a protein found in high levels on some cancer cells. By binding to HER2, it prevents the cancer cells from growing and multiplying. It also helps the immune system destroy these cancerous cells, reducing tumor size and slowing disease progression.

Benefits of Trastuzumab

• Highly effective in HER2-positive cancers
• Reduces tumor size and slows cancer growth
