Summary
Sparsentan blocks endothelin and angiotensin II receptors, and indomethacin reduces renal prostaglandins. Together they can reduce glomerular filtration and worsen kidney function, especially with volume depletion.
What this interaction means in plain words
Indomethacin and Sparsentan can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Indomethacin belongs to Musculoskeletal; Sparsentan belongs to Genitourinary.
Why it happens
Efferent arteriolar dilation from angiotensin blockade combined with NSAID-induced afferent vasoconstriction lowers glomerular filtration pressure.
What to do
Avoid regular NSAID use with sparsentan; if necessary, monitor serum creatinine, potassium and blood pressure closely.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
