lapatinib (Tykerb)

Lapatinib (Tykerb) is a targeted cancer medication used mainly to treat specific types of breast cancer. It works by blocking two proteins, HER2 and EGFR, that promote cancer cell growth. By inhibiting these proteins, lapatinib helps slow or stop the growth of cancer cells that rely on them. It is typically taken orally as a tablet, often in combination with other treatments. Lapatinib's targeted approach aims to reduce side effects compared to traditional chemotherapy, making it a valuable option for managing HER2-positive breast cancer. It is prescribed and monitored by healthcare professionals.
