Trastuzumab 440 mg

What is Trastuzumab 440 mg?

Trastuzumab 440 mg is a prescription medication used primarily in the treatment of certain types of cancer. It contains the active ingredient trastuzumab, a monoclonal antibody designed to target and treat tumors that overexpress the HER2 protein. This drug is an important therapeutic option for patients diagnosed with HER2-positive breast cancer and stomach cancer. Manufactured by Mylan Pharmaceuticals, Trastuzumab 440 mg is widely used in cancer treatment protocols across Canada and many other countries.

Trastuzumab 440 mg works by specifically targeting cancer cells that show an excess of the HER2 receptor, a protein that promotes cancer cell growth. By binding to these receptors, trastuzumab helps inhibit tumor progression, making it a critical component of oncology treatment regimens. Its administration is generally done via intravenous infusion under medical supervision, following strict dosage guidelines tailored to individual patient needs.

Uses of Trastuzumab 440 mg

• Treatment of HER2-positive breast cancer in early and metastatic stages
• Management of advanced HER2-positive stomach (gastric) and gastroesophageal junction adenocarcinoma
• Used in combination with chemotherapy to improve treatment effectiveness
• Post-surgery therapy to help prevent cancer recurrence

How Trastuzumab 440 mg Works

Trastuzumab 440 mg targets the HER2 protein, which is overexpressed in some cancer cells. By binding to the HER2 receptors on the cancer cell surface, it blocks the signaling pathways that stimulate cell growth and division. This targeted action helps slow or stop the progression of the cancer.

Additionally, trastuzumab stimulates the immune system to attack and destroy HER2-positive cancer cells. This combined mechanism helps improve patient outcomes and is a cornerstone in modern treatment strategies for certain cancers.

Benefits of Trastuzumab 440 mg

• Effectively slows growth of HER2-positive cancer cells
• Reduces risk of cancer recurrence after surgery
• Improves survival rates in early and advanced cancer stages
• Can be combined with chemotherapy to enhance treatment response
• Well-established safety profile under medical supervision

Dosage and Administration

Trastuzumab 440 mg is administered as an intravenous infusion by healthcare professionals. Dosage depends on the patient’s weight, disease condition, and treatment regimen. The initial dose is generally given over 90 minutes, with subsequent infusions lasting 30 to 90 minutes depending on tolerance. Treatment typically begins with a loading dose followed by maintenance doses every 3 weeks.

It is important to follow your prescribing physician's instructions carefully and attend all scheduled appointments for infusion. Do not alter doses or schedules without medical advice.
