Polycythemia vera (PV) is a progressive, chronic myeloproliferative neoplasm characterized by a primary, clonally-driven abnormal increase in red cell mass and elevations in platelet and white blood cell (WBC) counts [ 1 ]. Hydroxyurea helps convert the normal hemoglobin to fetal hemoglobin, which is a special type of hemoglobin that is immune to sickling.

Polycythemia vera (PV) is a condition that causes your bone marrow to produce too many red blood cells (RBCs). Chemistry and Mechanism of Action: Hydroxyurea is an inhibitor of the ribonucleotide reductase system that catalyzes the rate-limiting step in the de novo biosynthesis of purine and pyrimidine deoxyribonucleotides, that is, the conversion of ribonucleotide diphosphates to their deoxyribonucleoside diphosphate derivatives. While incidences of thrombosis and acute myeloid leukemia were stable over time, mortality and myelofibrosis varied depending on follow-up duration.

The resources on this page offer information and insights about Jakafi and treatment of patients with polycythemia vera (PV) who have had an inadequate response to or are intolerant of hydroxyurea. In PV, it lowers the number of red blood cells and platelets, which are cells that help blood clot. Hydroxycarbamide, also known as hydroxyurea, is a medication used in sickle-cell disease, chronic myelogenous leukemia, cervical cancer, and essential thrombocythemia. Polycythemia vera is a myeloproliferative neoplasm characterized by clonal hematopoiesis and an absolute increase in the red blood cell mass, with an associated leukocytosis and thrombocytosis. Incidence of transformation to myelofibrosis and mortality were significantly dependent on age and follow-up duration. Most of the health concerns associated with polycythemia vera are caused by the blood being thicker as a result of the increased red blood cells.
