Lubiprostone shows signs of slowing kidney function decline in chronic kidney disease

In adults with stage IIIb–IV chronic kidney disease, the constipation drug lubiprostone did not reduce gut-derived uremic toxins but preserved creatinine-based kidney function over 24 weeks. The benefit was linked to microbiome remodeling, increased polyamine production, and improved mitochondrial function rather than toxin lowering.
