atriopeptin

It is known by several names including auriculin, atriopeptin and atrial natriuretic factor.

Urodilatin is little affected by renal enzymes that inactivate atriopeptin, as the kidney elutes with urodilatin rather than with ANP.

Urodilatin renal natriuretic peptide potency equals or exceeds that of Atriopeptin [ANP-(99-126)], the prototype of cardiodilatin.
