Ibrance 125 — Palbociclib 125 mg (21 Capsules)
Ibrance 125 mg (Palbociclib) is an innovative targeted medication used to treat specific types of metastatic breast cancer. Palbociclib is a first-in-class inhibitor of cyclin-dependent kinases 4 and 6 (CDK4/6). By blocking these proteins, the drug slows the division of tumor cells and prevents disease progression, significantly increasing progression-free survival when used in combination with hormonal therapy.
Manufacturer: Pfizer, USA. Ibrance has made a breakthrough in oncology, becoming a standard of therapy for patients with hormone-receptor-positive cancer, allowing for long-term disease control while maintaining quality of life.
Key Features:
- ✅ Cycle Control Mechanism: Selectively blocks the transition of cancer cells from the resting phase to the division phase.
- ✅ Synergy with Hormone Therapy: Enhances the effect of aromatase inhibitors and fulvestrant, overcoming tumor resistance.
- ✅ Convenience of Use: The oral form in a 125 mg dosage is the standard starting dose for most patients.
Ibrance 125 mg is prescribed by an oncologist for the treatment of locally advanced or metastatic hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-) breast cancer:
- 🔹 In combination with an aromatase inhibitor: As first-line endocrine therapy in postmenopausal women.
- 🔹 In combination with fulvestrant: In women whose disease has progressed after prior hormonal therapy.
Sales Form: 1 bottle contains 21 capsules of 125 mg (designed for one full course/cycle).
