How does Tykerb (Lapatinib) work?
Tykerb, also known by its generic name lapatinib, is a medication used for the treatment of certain types of breast cancer. It belongs to a class of drugs called tyrosine kinase inhibitors (TKIs). Tykerb is specifically used in combination with another medication called capecitabine for the treatment of advanced or metastatic breast cancer that is HER2-positive.
HER2 (human epidermal growth factor receptor 2) is a protein that is overexpressed in some breast cancer cells, leading to uncontrolled growth and spread of the cancer. Tykerb works by targeting and inhibiting the activity of specific tyrosine kinases, including the HER2 receptor and the epidermal growth factor receptor (EGFR). By blocking the activity of these receptors, Tykerb helps to inhibit the growth of cancer cells and reduce the progression of the disease.
The dual inhibition of HER2 and EGFR is important because both receptors play a role in the growth and survival of cancer cells. By blocking both receptors, Tykerb can have a more comprehensive effect on inhibiting cancer cell growth.
Tykerb is usually taken orally in the form of tablets. After ingestion, the medication is absorbed into the bloodstream and reaches the cancer cells. It then binds to specific parts of the HER2 and EGFR receptors, preventing their activation and subsequent signaling pathways that promote cancer cell growth.
It’s important to note that Tykerb is typically used in combination with other treatments for breast cancer, such as chemotherapy or hormone therapy, as determined by the treating physician. The specific dosage and treatment plan will depend on individual factors, including the stage and characteristics of the cancer, as well as the patient’s overall health.
As with any medication, Tykerb can have side effects, and it’s essential to discuss potential risks and benefits with a healthcare professional before starting treatment.
