Ribociclib

Ribociclib is a targeted cancer therapy used primarily to treat certain types of breast cancer, especially hormone receptor-positive, HER2-negative tumors. It works by blocking specific proteins called cyclin-dependent kinases (CDKs), which are important for cancer cell growth and division. By inhibiting these proteins, ribociclib helps to slow down or stop the growth of cancer cells. This medication is usually combined with hormone therapy to enhance its effectiveness. Ribociclib is administered as a pill and is typically prescribed for patients whose cancer has spread or recurred.
