Tykerb is a brand name for the generic drug Lapatinib. It is an oral medication used for the treatment of advanced or metastatic breast cancer that is HER2-positive. HER2 is a protein that is overexpressed in certain types of breast cancer, and Tykerb works by blocking the signals that promote the growth and spread of HER2-positive breast cancer cells. It is often used in combination with other chemotherapy drugs or hormonal therapies to improve the effectiveness of treatment. Tykerb is a prescription drug and should only be used under the supervision of a healthcare professional.

Tykerb (Lapatinib) is a medication used to treat HER2-positive breast cancer. It works by targeting and blocking the activity of two proteins known as HER2 (human epidermal growth factor receptor 2) and EGFR (epidermal growth factor receptor), which are involved in the growth and spread of cancer cells.

HER2 is overexpressed in approximately 20-25% of breast cancer cases and is associated with more aggressive and faster-growing tumors. Tykerb blocks the HER2 receptor, which slows down the growth of cancer cells and can help shrink tumors.

EGFR is also a receptor involved in the growth and division of cells. In some cases, EGFR can work together with HER2 to promote the growth of cancer cells. Tykerb can also block the activity of EGFR, which further slows down the growth of cancer cells.

Tykerb is taken orally and is usually prescribed in combination with other medications such as chemotherapy or hormonal therapy. By targeting both HER2 and EGFR receptors, Tykerb can help improve the effectiveness of other cancer treatments and may also reduce the risk of cancer recurrence.

It is important to note that Tykerb is only effective against HER2-positive breast cancer and is not used to treat other types of breast cancer. Your doctor can determine if Tykerb is an appropriate treatment option for you based on your individual medical history and cancer diagnosis.

Tykerb (Lapatinib) is not a traditional chemotherapy drug, but it is often used in combination with chemotherapy to treat HER2-positive breast cancer.

Chemotherapy drugs work by killing rapidly dividing cells, including cancer cells. They are often given intravenously and can have side effects such as nausea, hair loss, and fatigue.

On the other hand, Tykerb is a targeted therapy that works by blocking the activity of certain proteins involved in the growth and spread of cancer cells. It is taken orally as a pill and can have side effects such as diarrhea, nausea, and rash.

While Tykerb is not considered a chemotherapy drug, it is often used in combination with chemotherapy as part of a comprehensive treatment plan for HER2-positive breast cancer. The combination of Tykerb and chemotherapy has been shown to be more effective than chemotherapy alone in treating HER2-positive breast cancer.

Your doctor can provide more information about the use of Tykerb and chemotherapy in the treatment of breast cancer and help you determine the most appropriate treatment plan based on your individual medical history and cancer diagnosis.
