Uses of Palbociclib

Palbociclib is approved for use in combination with aromatase inhibitors or letrozole as a firstline treatment for postmenopausal women with HR+/HER2 breast cancer. It is also indicated for use in combination with the antiestrogen medication fulvestrant in patients who have previously received endocrine therapy. This medication is particularly beneficial for patients with advanced or metastatic breast cancer, where traditional treatments may not be effective.

ເຮັດແນວໃດມັນເຮັດວຽກ

Palbociclib works by inhibiting specific proteins known as cyclindependent kinases 4 and 6 (CDK4/6). These proteins play a crucial role in regulating the cell cycle, which is the process by which cells grow and divide. By blocking CDK4/6, Palbociclib prevents cancer cells from progressing through the cell cycle, effectively slowing their growth and proliferation. This mechanism allows other treatments, such as hormone therapy, to work more effectively against the cancer.

ວິທີໃຊ້ຢາແລະບໍລິຫານ

Palbociclib is administered orally in the form of a tablet. The standard adult dosage is typically 125 mg taken once daily for 21 consecutive days, followed by a 7day break (a 28day cycle). This regimen may vary based on individual patient factors, including liver function and tolerance to the medication. It is important for patients to follow their healthcare provider's instructions regarding dosage and administration.

• Strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir) can increase Palbociclib levels, leading to toxicity.
• Strong CYP3A4 inducers (e.g., rifampin, St. John's Wort) can decrease Palbociclib levels, reducing its effectiveness.
• Other medications that affect liver enzymes may also interact with Palbociclib.
