ruxolitinib

Ruxolitinib is a medication that helps treat certain blood disorders and some types of cancer by targeting specific proteins involved in the body's immune response and blood cell production. It works by inhibiting Janus kinases (JAKs), which are enzymes that transmit signals inside cells to promote inflammation and abnormal growth. By blocking these signals, ruxolitinib can reduce symptoms like excessive spleen size, improve blood counts, and help control disease progression. It is commonly used for conditions such as myelofibrosis and polycythemia vera and must be prescribed and monitored by a healthcare professional.
