Trastuzumab For Injection

Product Description

Trastuzumab is a medication used to treat certain types of cancer, notably HER2-positive breast cancer and HER2-positive metastatic gastric or gastroesophageal junction adenocarcinoma. It is a monoclonal antibody that targets the HER2 protein, which is overexpressed in some cancer cells.

The dosage of trastuzumab can vary depending on factors such as the specific type and stage of cancer being treated, as well as the patients weight and overall health. Trastuzumab is typically administered as an intravenous (IV) infusion.

For HER2-positive breast cancer, the dosage might be 440 mg given initially as a loading dose, followed by subsequent doses at a lower maintenance dosage. The treatment schedule can vary depending on whether trastuzumab is used in combination with other chemotherapy drugs or as a standalone therapy.

As with any medication, its important to follow the dosage and administration instructions provided by your healthcare provider. They will tailor the treatment plan to your specific needs and monitor you for any potential side effects.

Mechanism and Function

Trastuzumab is a monoclonal antibody that specifically targets and binds to the HER2 receptor, which is found in higher quantities on certain cancer cells. By doing so, it blocks the growth signals, helping to slow or stop the progression of HER2-positive breast and gastric cancers. This targeted action makes Trastuzumab an important therapy in oncology.


Preparation and Administration

This medication is formulated as a lyophilized powder that needs to be reconstituted with sterile water before being administered intravenously. Only healthcare professionals should handle preparation and infusion, ensuring accurate dosing and patient safety. Strict adherence to physician instructions is crucial throughout the treatment process.


Storage and Packaging

Trastuzumab for Injection should be stored in a cool, dry place and protected from light to maintain its efficacy. The product comes in vials, each usually packed individually per box, with strengths of either 150 mg or 440 mg. Always check expiration dates and storage instructions prior to use.
