All of the following drugs are useful in nephrogenic diabetes insipidus except

The polyuria and polydipsia of nephrogenic DI are not affected by treatment with standard doses of DDAVP. Treatment with conventional doses of a thiazide diuretic and/or amiloride in conjunction with a low-sodium diet and a prostaglandin synthesis inhibitor (e.g., indomethacin) usually reduces the polyuria and polydipsia by 30-70% and may eliminate them completely in some patients. ref : Harrisons 20th ed 2279.
