Fostamatinib is an oral spleen tyrosine kinase (SYK) inhibitor that has been approved for the treatment of chronic immune thrombocytopenia (ITP) in adults who have not responded sufficiently to previous treatment. It inhibits the activity of spleen tyrosine kinase (SYK), reduces the attack and destruction of platelets by immune cells, increases the number and function of platelets, and relieves patients' bleeding symptoms.
Precautions for Fostamatinib

Throughout the treatment process, the doctor will pay close attention to the patient's diarrhea symptoms and take appropriate treatment measures according to the specific situation.
Hypertension
Fostamatinib can affect certain signaling pathways in the body related to blood pressure regulation. For patients who already have hypertension, Fostamatinib may further increase blood pressure and increase the risk of cardiovascular diseases such as myocardial infarction and stroke. Before the dose of Fostamatinib stabilizes, blood pressure should be monitored every 2 weeks, and appropriate treatment measures should be taken according to the patient's specific situation.
