Abemaciclib

Abemaciclib is an oral targeted therapy used to treat certain types of advanced or metastatic breast cancer. As a cyclin-dependent kinase (CDK) 4 and 6 inhibitor, it slows the growth and division of cancer cells by interrupting key signals that drive cell cycle progression. It is particularly effective in hormone receptor-positive (HR+), HER2-negative breast cancer. This guide provides comprehensive information on Abemaciclib, covering its uses, dosage, side effects, interactions, benefits, and answers to common questions.

Kini Abemaciclib?

Abemaciclib selectively inhibits CDK4 and CDK6, enzymes that regulate the transition from the G1 to S phase of the cell cycle. By preventing this transition, Abemaciclib halts uncontrolled cell proliferation seen in many cancers. It is approved for use in HR+, HER2- breast cancer that is advanced or metastatic, either as a standalone treatment or in combination with endocrine therapy.
