How does avatrombopag maleate tablets work?

The main ingredient of avatrombopag maleate tablets is avatrombopag, which is a thrombopoietin(TPO) receptor agonist. Its main function is to stimulate the proliferation and differentiation of megakaryocytes in bone marrow progenitor cells, thereby increasing platelet production. This role is particularly important in patients with chronic liver disease, as these patients are often accompanied by thrombocytopenia, which significantly increases the risk of bleeding during surgical treatment. Avatrombopag Maleate Tablets can regulate platelet balance in the body, promote hemostasis, and reduce bleeding in patients with liver disease during invasive examinations or surgeries.

Avatrombopag maleate is particularly indicated for adult patients with thrombocytopenia associated with chronic liver disease who are scheduled for elective diagnostic procedures or surgery. According to relevant studies, this drug has shown good efficacy in treating thrombocytopenia and can effectively increase platelet counts, thereby reducing the risk of bleeding.

Avatrombopag Maleate Tablets are oral medications and are recommended to be taken with food to increase the bioavailability of the drug. Platelet counts are measured before treatment and during diagnostic tests/on the day of surgery to ensure that platelets are elevated to target levels. The usual medication regimen is once a day for 5 consecutive days, and the dose is adjusted based on the patient's platelet count.

While avatrombopag maleate works well in treating thrombocytopenia, it may cause some side effects. Common side effects include fever, abdominal pain, nausea, etc. In addition, a small number of patients may experience serious side effects such as allergic reactions, hyponatremia, peripheral edema, and thromboembolic complications. Therefore, it is necessary to closely observe the patient's response during use and adjust the treatment plan in a timely manner.
