Cloning CDK4/6 Inhibitor Palbociclib Dose 125mg

Palbociclib is a kind of drug that targets the CDK4 and CDK6 kinases, which helps treat hormone-positive, HER2-negative breast cancer that’s spread to other parts of the body. The way it works is by stopping cells from dividing, which slows down the growth of the cancer. You can get this in pill form in three strengths—75, 100, and 125 mg.

The usual dose for adults is a 125 mg pill each day, taken for 21 days out of every 28 days. So, during each 28-day stretch, you take 21 pills from the bottle. Palbociclib stops the CDK4 and CDK6 proteins from turning on.

These proteins are like controllers that make cells split, so blocking them is like putting the brakes on cancer. By doing this, the drug encourages cancer cells to die and also keeps them from spreading or moving to new areas of the body.
