Tykerb 250 mg Tablet – Lapatinib for Breast Cancer Treatment

Tykerb 250 mg Tablet contains lapatinib, a tyrosine kinase inhibitor used in the treatment of HER2-positive breast cancer. Lapatinib works by inhibiting the growth of cancer cells by targeting and blocking proteins that promote cancer cell growth, specifically HER2/neu (ErbB2) and EGFR (epidermal growth factor receptor).

Uses:

1. HER2-Positive Breast Cancer: Used in combination with other medications, such as capecitabine, for the treatment of advanced or metastatic breast cancer in patients whose disease has progressed on other HER2-targeting treatments (e.g., trastuzumab).
2. Combination Therapy: Often prescribed alongside other chemotherapy drugs for improved effectiveness against cancer cells.

How Tykerb 250 mg Tablet Works:

Lapatinib targets and binds to the HER2/neu and EGFR receptors present on the surface of certain cancer cells. By blocking the signaling pathways, it prevents cancer cells from growing and dividing, slowing the progression of the disease.
