API Description: Lapatinib tosylate is an oral cancer medication used primarily to treat HER2-positive breast cancer. It works by inhibiting two proteins, HER2 and EGFR, that promote cancer cell growth. Lapatinib is often used in combination with other drugs like capecitabine or letrozole in patients with advanced or metastatic breast cancer, especially when other treatments have not been effective.
