About Ardelyx

Ardelyx makes medicines for people with gut and kidney problems. These drugs help adults manage painful stomach issues and complex mineral levels. The company focuses on creating treatments that work locally in the intestines.

Treating the Gut and Kidneys

XPHOZAH: Therapy used to lower high phosphorus levels in adults on kidney dialysis.
RDX10531: Next-generation inhibitor currently under development for multiple medical uses.
Discovery Assets: Early programs targeting potassium and electrolyte disorders in patients with heart or kidney disease.

Global Partners and New Trials

Stopping Absorption at the Source
