Palbociclib

Palbociclib is a medication primarily used to treat certain types of breast cancer, specifically hormone receptor-positive and HER2-negative breast cancer. It works by blocking specific proteins called cyclin-dependent kinases (CDKs) that help cancer cells grow and divide. By inhibiting these proteins, Palbociclib slows down the progression of cancer. It is often used in combination with other therapies, such as hormonal treatments, to enhance the effectiveness of treatment. Patients typically take it as a pill, and it is part of a targeted approach to cancer therapy, aiming to minimize side effects while controlling the disease.
