Metabolic alkalosis can be treated with amiloride or triamterene but not with spironolactone. Both amiloride and triamterene inhibit the apical sodium ion channel in the collecting duct. Spironolactone, which is a mineralocorticoid receptor antagonist that works upstream of the defective sodium ion channel, does not correct the alkalosis or the hypertension.
