Rationale:
1. Desmopressin acetate (DDAVP) is a vasopressin.
2. Oxybutynin (Ditropan) is an anticholinergic that relaxes the smooth muscle of the bladder, allowing for an increase in bladder capacity and a delay in the initial desire to void.
3. Imipramine (Tofranil) is a tricyclic antidepressant.
4. Spironolactone (Aldactone) is a potassium-sparing diuretic.
