去氧皮質酮
皮質類固醇 - 鹽皮質激素
長效型鹽皮質激素替代療法,用於治療患有原發性腎上腺皮質機能減退症(愛迪生氏病)的犬貓。開始治療前必須確診。若出現愛迪生氏危象,必須先進行靜脈輸液(生理食鹽水)補充水分。
作用機制: Acts as a **mineralocorticoid** replacement. It binds to mineralocorticoid receptors in the distal renal tubules → increases sodium reabsorption and promotes potassium excretion → restores electrolyte balance and maintains extracellular fluid volume and blood pressure.
