Why is this medication prescribed?

Kisqali (generic name ribociclib) is a prescription medication that is primarily used in the treatment of certain types of breast cancer. It belongs to a class of drugs called cyclin-dependent kinase 4/6 (CDK4/6) inhibitors.

Kisqali is prescribed for postmenopausal women with hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) advanced or metastatic breast cancer. It is used in combination with an aromatase inhibitor, which is another type of medication that blocks the production of estrogen, or with fulvestrant, a selective estrogen receptor degrader.

The main goal of Kisqali treatment is to slow down or stop the growth of cancer cells by inhibiting CDK4/6 enzymes. These enzymes play a crucial role in promoting cell division and growth, and by blocking them, Kisqali helps to prevent cancer cells from multiplying rapidly.

Kisqali is typically prescribed as part of a comprehensive treatment plan for breast cancer, which may also include surgery, radiation therapy, and other medications. The specific treatment regimen depends on various factors, such as the stage of cancer, the presence of other health conditions, and individual patient characteristics. It is important to consult with a healthcare professional for personalized medical advice and information about the appropriate use of Kisqali.
