Vivitra 150 mg Injection

Introduction to Vivitra 150 mg Injection

Vivitra 150 mg Injection is used in the treatment of breast and stomach Cancer. It works by killing the cancer cells by inhibiting HER2 (human epidermal growth factor receptor protein). In HER2-positive patients, breast cancer cells have high levels of HER2 proteins, which can promote the rapid growth of tumors by acting as signals to cancer cells.

This medication is also used to treat metastatic gastric cancer with increased levels of HER2 proteins. HER2-positive breast cancers are more aggressive in nature. The targeted therapy for HER2-positive breast cancer works by selectively targeting the proteins responsible for the growth, development, and spread of cancer.

Use effective birth control during the treatment and for at least 7 months after the final dose. Vivitra 150 mg Injection is not recommended for patients aged under 18, patients who have severe breathing problems or need oxygen treatment.
