Lapatinib Ditosylate is the technical name for the medication most commonly known simply as Lapatinib [1]. It's a prescription drug used to treat a specific type of breast cancer [1]. Here's a breakdown of what you need to know about Lapatinib Ditosylate:
What is Lapatinib Ditosylate (Lapatinib) used for?
Lapatinib is used to treat HER2-positive breast cancer. HER2 stands for Human Epidermal Growth Factor Receptor 2, a protein that can fuel the growth of some breast cancers [1, 2]. Lapatinib is typically prescribed in combination with other chemotherapy medications for:
- Advanced or metastatic breast cancer: This refers to cancer that has spread beyond the breast to other parts of the body [2].
- Early-stage HER2-positive breast cancer: In some cases, lapatinib may be used with other medications after surgery to reduce the risk of cancer recurrence [2].
How does Lapatinib Ditosylate (Lapatinib) work?
Lapatinib belongs to a class of drugs called tyrosine kinase inhibitors (TKIs) [1]. It works by blocking the activity of HER2 receptors on the surface of cancer cells. By inhibiting these receptors, Lapatinib disrupts the signals that tell cancer cells to grow and divide [2, 3]. This can help slow down the growth and spread of HER2-positive breast cancer.
Dosage and Administration:
Lapatinib Ditosylate comes as a tablet taken orally, usually once a day, with or without food [1]. It's important to follow your doctor's instructions regarding dosage and duration of treatment.
