What is Fostamatinib
Fostamatinib is an oral, spleen tyrosine kinase (SYK) inhibitor indicated for the treatment of thrombocytopenia in adults with chronic immune thrombocytopenia (ITP) who have had an insufficient response to a previous treatment. Routine monitoring of complete blood count, including neutrophils, liver function tests, and blood pressure is necessary for assessing ongoing fostamatinib safety and tolerability for an individual patient.
Management of some adverse reactions, including neutropenia, hepatotoxicity, hypertension, and diarrhea, may require fostamatinib dosage interruption, reduction, or discontinuation.
