Summary
Pacritinib is used to treat myelofibrosis, which is a type of bone marrow cancer. It helps reduce spleen size and improve symptoms like fatigue and abdominal discomfort. This medication is often used alongside other therapies to manage the condition and improve the quality of life for patients.
Pacritinib works by inhibiting specific proteins called kinases, which are involved in the growth and survival of cancer cells. By blocking these proteins, it helps reduce spleen size and improve symptoms in patients with myelofibrosis, effectively managing the disease and enhancing quality of life.
The usual starting dose of Pacritinib for adults is 200 mg taken twice daily. The maximum recommended dose is 400 mg per day. It is typically taken as a long-term treatment for managing myelofibrosis, and the dosage may be adjusted based on individual response and side effects.
Common side effects of Pacritinib include stomach upset, such as nausea and diarrhea, which are usually mild to moderate. Taking the medication with food might help reduce discomfort. If severe or persistent stomach issues occur, it's important to talk with a doctor.
Pacritinib can increase the risk of bleeding and heart problems, especially in elderly patients. It should not be used if you have severe liver problems or are allergic to its ingredients. Regular monitoring and informing your doctor about your medical history are crucial for safe use.
