Generic Name: Palbociclib
Mechanism of Action:
Palbocap is a selective cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitor. Cyclin D1 and CDK4/6 are downstream of signaling pathways, which lead to cellular proliferation.
Palbocap reduces proliferation of breast cancer cells by preventing G1 to S phase cell cycle progression.

• An aromatase inhibitor as initial endocrine-based therapy in postmenopausal women or in men
• Fulvestrant in patients with disease progression following endocrine therapy.
