Description
Palbocib 125 mg contains Palbociclib, a selective cyclin-dependent kinase (CDK) 4 and 6 inhibitor. It is commonly prescribed in combination with endocrine therapy such as aromatase inhibitors or fulvestrant for HR-positive, HER2-negative breast cancer.
🔬 Mechanism of Action
Palbociclib blocks CDK4 and CDK6 enzymes, which regulate the cell cycle transition from the G1 phase to the S phase. By inhibiting this pathway, it prevents cancer cells from multiplying, thereby slowing tumor growth and enhancing the effect of hormonal therapy.

- HR-positive, HER2-negative advanced or metastatic breast cancer
