What Kind of Medicine Is This?
To put it simply, Pacritinib is a prescription medicine used to treat bone marrow cancer. Your bone marrow is the spongy tissue inside your bones where your body makes new blood cells. When something goes wrong in this tissue, targeted medicines like this help manage the condition.
This medicine works in a clever way inside your body. Cancer cells rely on special proteins to grow and multiply quickly. Pacritinib blocks these specific proteins, which slows down or stops the cancer cells from spreading.
You might also see this medicine sold under the brand name Vonjo. Knowing both names helps you recognize your prescription at the pharmacy.
