Upacicalcet is an intraventricular calcium mimetic, a SHPT available for human hemodialysis, that inhibits excessive parathyroid hormone (PTH) secretion by directly acting on parathyroid cell membrane calcium-sensitive receptors, thereby lowering blood levels of PTH.Upacicalcet is an orthosteric modulator of calcium-sensitive receptors and prevents adenine-induced secondary vascular calcification and bone disease in a rat model of adenine-induced secondary hyperparathyroidism.
