Used primarily to treat thrombocythemia, a condition characterized by excessive production of platelets in the blood. It works by inhibiting the maturation of megakaryocytes, the bone marrow cells responsible for platelet formation, thereby reducing platelet count and lowering the risk of thrombosis and related complications. Commonly prescribed in patients with essential thrombocythemia, especially those at high risk for clotting events. Helps manage symptoms such as headaches, dizziness, and visual disturbances caused by high platelet levels. Not typically used as a first-line treatment in all cases due to potential cardiovascular side effects, but remains an important option for targeted platelet reduction.
