Which pharmacologic options are used for nocturnal enuresis?

• A. Desmopressin (DDAVP)
• B. Imipramine
• C. Anticholinergics
• D. All of the above

Answer: (D)

Nocturnal enuresis can be addressed through different pharmacologic actions that target the underlying patterns of urination and bladder function. Desmopressin is a synthetic vasopressin analog that lowers nighttime urine production, helping children who swallow large volumes at night or have an osmotic/diurnal pattern of polyuria. Imipramine, a tricyclic antidepressant, can increase functional bladder capacity and has anticholinergic effects that reduce bladder contractions, making it helpful when the bladder storage function is a factor. Anticholinergic medications, such as oxybutynin or tolterodine, directly dampen detrusor overactivity and help with bladder overactivity that can contribute to bedwetting, especially if there are signs of daytime symptoms or detrusor instability. Because these approaches address different mechanisms—urine production, bladder storage capacity, and detrusor activity—each has a role, and they can be used alone or tailored to a patient’s pattern. That’s why all of these options are considered usable for nocturnal enuresis.
