Ruxolitinib in Apotex's Formulation: Understanding the Combination Therapy
Introduction
Ruxolitinib, a Janus kinase (JAK) inhibitor, has been widely used in the treatment of myelofibrosis and polycythemia vera. Apotex, a Canadian pharmaceutical company, has developed a formulation of ruxolitinib, which has gained attention in the medical community.
