What exactly does eflornithine tablets do?

Eflornithine tablets (eflornithine) is a targeted ornithine decarboxylase (ODC) inhibitor. Its pharmacological mechanism is to block the polyamine synthesis pathway, thereby inhibiting cell division and proliferation. It is especially suitable for controlling the spread of malignant tumor cells. At present, eflornithine tablets are widely studied and used in the maintenance treatment of high-risk neuroblastoma (HRNB). It is mainly used for patients who have received multi-modal and multi-drug treatment and have a certain response to anti-GD2 immunotherapy to reduce their risk of tumor recurrence.

High-risk neuroblastoma is a pediatric tumor that originates in the sympathetic nervous system and is highly aggressive and prone to recurrence. Although there are currently a variety of comprehensive treatments including chemotherapy, stem cell transplantation, radiotherapy and immunotherapy, the long-term progression-free survival rate is still low. The main purpose of the introduction of eflornithine tablets is to serve as one of the "maintenance treatment" strategies to further delay the recurrence of the disease and improve the overall survival rate based on the good response to the original treatment. Its innovation lies in interfering with the core link of tumor metabolism pathways, especially by inhibiting the expression of key enzymes such as ODC, blocking the production of polyamine substances, which are considered to be the "fuels" that promote the rapid division and metastasis of cancer cells.

In addition to being used for neuroblastoma, eflornithine tablets have also been used for the treatment of atypical indications such as African trypanosomiasis, showing its multiple potential in the field of antiprotozoa and tumors. In recent years, more and more studies have begun to focus on its maintenance therapeutic value in rare cancer types, especially in the context of the limited effectiveness of other treatments. Eflornithine tablets provide an innovative intervention model.
