Introduction: What is Palbociclib?
Palbociclib is a targeted therapy medication primarily used in the treatment of certain types of breast cancer. It belongs to a class of drugs known as cyclindependent kinase (CDK) inhibitors. By interfering with the cancer cell cycle, Palbociclib helps to slow down or stop the growth of cancer cells, making it a vital option for patients with hormone receptorpositive, human epidermal growth factor receptor 2negative (HR+/HER2) breast cancer.
