Deoxycorticsterone acts as a precursor to aldosterone. Deoxycorticosterone is not a major secretory hormone. It is produced from progesterone by 21beta-hydroxylase and is converted to corticosterone by 11beta-hydroxylase. Corticosterone is then converted to aldosterone by aldosterone synthase. Deoxycorticosterone stimulates the collecting tubules in the kidney to continue to excrete potassium in much the same way that aldosterone does. Deoxycorticosterone has about 1/20 of the sodium retaining power of aldosterone and about 1/5 the potassium excreting power of aldosterone . Deoxycorticosterone can be used to treat adrenal insufficiency. In particular, desoxycorticosterone acetate (DOCA) is used as replacement therapy in Addison's disease."}]
