Which of the following is the treatment of choice in patients with neurogenic diabetes insipidus?
**Core Concept**
Neurogenic diabetes insipidus is a condition characterized by the deficiency of antidiuretic hormone (ADH), also known as vasopressin, leading to an inability to concentrate urine and resulting in excessive thirst and polyuria. The treatment of choice aims to replace this deficiency with synthetic ADH.
**Why the Correct Answer is Right**
Desmopressin, a synthetic analogue of vasopressin, is the treatment of choice for neurogenic diabetes insipidus. It has a longer duration of action and a more selective action on the V2 receptors in the kidneys, promoting water reabsorption and reducing urine output. Desmopressin can be administered intranasally, orally, or subcutaneously, depending on the patient's needs.
**Why Each Wrong Option is Incorrect**
**Option A:** Hydrochlorothiazide is a thiazide diuretic, which would worsen the condition by increasing urine output.
**Option B:** Metolazone is another diuretic that would exacerbate the symptoms of diabetes insipidus.
**Option C:** Furosemide is a loop diuretic, which would further increase urine production and worsen the condition.
**Clinical Pearl / High-Yield Fact**
Desmopressin is a high-yield medication that is often used in the treatment of central diabetes insipidus, nocturnal enuresis, and hemophilia A and B. It is essential to note that patients with diabetes insipidus require lifelong treatment with desmopressin to manage their condition.
**Correct Answer:** C. Desmopressin
