-
A low-molecular weight substance, possibly from the hypothalamus, which is released due to plasma volume expansion. It causes natriuresis in part by inhibiting sodium potassium ATPase. The development of hypertension may be the consequence of an abnormality in volume regulation induced by a defect in the renal response to the natriuretic effect of the natriuretic hormone. Do not confuse with ATRIAL NATRIURETIC FACTOR or cardionatrin which is a different, well characterized hormone.
