Understanding Abemaciclib #
Abemaciclib is a significant medication in the fight against advanced breast cancer. As a chemotherapy drug, it can be used as a standalone treatment or combined with other chemotherapy medications to combat cancer that has metastasized or spread to other organs. By inhibiting protein kinases—proteins that assist in cancer cell division—Abemaciclib helps to slow down the growth and spread of cancer cells. Additionally, it can be combined with aromatase inhibitors as part of hormone therapy for breast cancer. Available in tablet form, this prescription-only medication should be taken as directed by a healthcare professional.
