Medical Uses
FILSPARI (sparsentan), from Travere Therapeutics, is a dual endothelin and angiotensin II receptor antagonist indicated to reduce proteinuria in adults with primary IgA nephropathy (IgAN) who are at risk of rapid disease progression (urine protein-to-creatinine ratio ≥1.5 g/g).
FILSPARI blocks both endothelin type A receptors and angiotensin II type 1 receptors, two pathways involved in glomerular injury and proteinuria in IgA nephropathy, reducing protein leakage and slowing kidney function decline.
