Herceptin Trastuzumab Injection (150mg)
Herceptin Trastuzumab Injection (150mg) is a targeted therapy medication primarily used in the treatment of certain types of breast cancer and gastric cancer that overexpress the HER2 protein. The active ingredient, Trastuzumab, is a monoclonal antibody that specifically binds to the HER2 receptor, inhibiting the growth of cancer cells that rely on this protein for proliferation. This injection is typically administered intravenously and is often part of a comprehensive treatment plan that may include chemotherapy or other therapies. The formulation of Herceptin includes Trastuzumab as the active component, along with various excipients to ensure stability and efficacy. By targeting HER2-positive tumors, Herceptin plays a crucial role in improving patient outcomes and survival rates in those diagnosed with aggressive forms of cancer.

Herceptin Trastuzumab Injection (150mg) Action Mechanism
Herceptin Trastuzumab Injection (150mg) works by binding to the HER2 receptor on the surface of cancer cells, blocking the receptor's ability to receive growth signals. This action inhibits the proliferation of HER2-positive cancer cells and triggers immune-mediated responses that help destroy these cells. Additionally, Herceptin may induce apoptosis, or programmed cell death, in cancer cells, further contributing to its therapeutic effects. By specifically targeting HER2, Herceptin minimizes damage to normal cells, which is a significant advantage over traditional chemotherapy.
How should Herceptin Trastuzumab Injection (150mg) be used
Herceptin Trastuzumab Injection (150mg) should be used under the supervision of a healthcare professional. The typical dosage is determined based on the patient's body weight and the specific treatment regimen. It is usually administered as an intravenous infusion, with the initial dose often being higher to saturate the HER2 receptors, followed by maintenance doses given at regular intervals. Patients should follow their healthcare provider's instructions regarding the timing and frequency of doses to ensure optimal therapeutic effects and minimize potential side effects.
When is the best time to take Herceptin Trastuzumab Injection (150mg) ?
