Does fostatinib affect blood pressure?

Fostamatinib is a spleen tyrosine kinase (SYK) inhibitor, mainly used to treat chronic immune thrombocytopenia (ITP). During clinical use, fostatinib may have an impact on blood pressure, so special attention needs to be paid to the risks related to hypertension.

1. The effect of fostatinib on blood pressure: Clinical studies have shown that fostatinib may cause an increase in blood pressure, and some patients may develop hypertension or worsen their existing hypertension during use. This may be related to its inhibitory effect on the SYK signaling pathway, affecting vasoconstriction and blood flow regulation, resulting in increased blood pressure. Additionally, fostatinib may cause fluid retention, which may also increase blood pressure levels to some extent.

2. Medication precautions for patients with hypertension: For patients with existing hypertension, their blood pressure should be controlled before taking fostatinib. Blood pressure levels should be monitored regularly during treatment, especially in the first few weeks of starting the medication. If a patient's blood pressure rises significantly, doctors may need to adjust the dose of antihypertensive medications or consider reducing the dose of fostatinib or even suspending its use.

3. How to prevent and manage elevated blood pressure: Patients should maintain a healthy lifestyle, such as reducing salt intake, maintaining moderate exercise, and avoiding factors that may cause elevated blood pressure (such as excessive drinking, smoking, etc.). If symptoms of high blood pressure, such as headache, dizziness, blurred vision or chest tightness, occur during treatment, you should seek medical attention promptly and adjust your medication plan.

Fostatinib may affect blood pressure, causing high blood pressure or worsening existing high blood pressure. Therefore, patients using this drug should monitor their blood pressure regularly and take appropriate management measures under the guidance of a doctor to ensure the safety and effectiveness of treatment.
