Mode of action
Frusemide: Acts by blocking the Na⁺ K⁺-2Cl⁻ cotransport (NKCC2)
Spironolactone; it is a specific antagonist of aldosterone acts through competitive binding of receptors at the aldosterone-dependent sodium-potassium exchange site in the distal convoluted renal tubule causes increased amounts of sodium and water to be excreted, while potassium is retained. (Aldosterone interacts with a cytoplasmic mineralocorticoid receptor to enhance the expression of the Na⁺ K⁺-ATPase and the Nat channel involved in a Na+ K+ transport in the distal tubule. It binds to this mineralcorticoid receptor, blocking the actions of aldosterone on gene expression. Aldosterone is a hormone; its primary function is to retain sodium and excrete potassium in the kidneys).
