How much does a box of 2025 Spasentan/Sparsentan cost?

斯帕森坦/司帕生坦（Sparsentan）是一种新型药物，主要用于治疗原发性免疫球蛋白A肾病（IgAN）的患者。这种疾病是一种以免疫球蛋白A（IgA）沉积在肾脏为特征的慢性肾脏疾病，通常会导致肾功能的逐渐衰退。 Sparsentane's mechanism of action involves the modulation of specific receptors within the kidney and is designed to protect kidney function by reducing inflammatory and fibrotic processes within the kidney.

Specifically, sparsentan combines the properties of an angiotensinII receptor antagonist (ARB) and a prostaglandin E1 analogue, which enables it to effectively improve renal hemodynamics and reduce tubulointerstitial fibrosis.通过这些机制，斯帕森坦不仅可以减缓IgAN患者的疾病进展，还可以改善他们的生活质量。

不过，由于斯帕森坦可能带来某些不良反应，因此它只能在特定的医疗监督下使用。 Distribution of this drug is restricted by the Filspari REMS (Risk Evaluation and Mitigation Strategy) program, which is designed to ensure that patients can receive this new drug in a safe environment. This restricted distribution plan involves strict management of medical institutions, doctors and patients to ensure adequate risk assessment and patient education during use.

由于斯帕森坦原研药尚未在国内上市，其价格目前仍不明确。 The drug has been on the market for a short time overseas and is available in two common specifications: 200mg*30 tablets and 400mg*30 tablets. The price of each box of the European version may exceed more than 40,000 yuan (the actual price is affected by exchange rate fluctuations), and the overall cost is relatively high. At the same time, generic drugs of sparsentan are also available in overseas markets, and their ingredients are basically the same as the original drug.例如，老挝某药厂生产的400mg*30片规格，每盒售价大约七千人民币（价格受汇率影响而有所波动）。
