What is Verzenio

GENERIC NAME(S): Abemaciclib

This medication is used to treat certain types of breast cancer. Abemaciclib works by slowing or stopping the growth of cancer cells. It belongs to a class of drugs known as kinase inhibitors. Verzenio works to stop these proteins and cells as they are moving to grow and divide2. It slows down the cell growth and division, which causes cancer cells to become inactive or even die. In preclinical studies, continuous exposure to Verzenio slowed down CDK4 & 6 proteins, which delayed cancer cells from growing and dividing.
