Palbociclib is a CDK4/6 inhibitor used for HR /HER2breast cancer patients. It’s made to stop cells from moving to the next stage of their growth cycle. The drug comes in three doses—75 mg, 100 mg, and 125 mg—in capsule form.
The usual dose is 125 mg, taken every day for 21 days in every 28-day cycle. Each bottle has 21 capsules, just enough for one full cycle of treatment. The way it works is by focusing on CDK4/6 enzymes, which are key for cell growth.
By doing this, it helps slow down cancer cell growth. Palbociclib was created to help treat HR and HER2- breast cancer, which is a hormonal therapy responsive kind of cancer. It’s a big deal for people who haven’t tried other hormonal therapies yet.
