Contents of the pack
Filspari contains the active substance esparsentan. Filspari blocks the receptors of two hormones called endothelin and angiotensin, which are involved in the regulation of kidney function.
Filspari is used to treat primary immunoglobulin A (IgA) nephropathy in adults with a urinary protein excretion of ≥1.0 g/day (or a urinary protein-to-creatinine ratio of ≥0.75 g/g).
Primary IgA nephropathy is a disease caused by the immune system (the body's natural defenses) that produces a defective version of an antibody called immunoglobulin A (IgA), which accumulates in the small blood vessels of the kidney, called glomeruli, responsible for filtering the blood. This accumulation damages the glomeruli, causing blood and protein to filter into the urine.
Filspari blocks the receptors of two hormones called endothelin and angiotensin that are involved in the regulation of processes in the kidney, such as inflammation, which lead to the progression of kidney damage. By blocking these receptors, Filspari reduces the amount of protein that filters into the urine and, therefore, helps to slow the progression of the disease.
Do not take Filspari
