There are evidences that adrenal hormones regulate extrarenal potassium homeostasis. The present study evaluated the effect of Florinef modulation on extrarenal mechanisms in potassium adaptation of adrenalectomized rats. The results demonstrated that the rats treated with Florinef had serum potassium levels at normal range probably due to an increase in cellular potassium uptake consequently to en enhanced activity of Na-K-ATPase.
