Does Desmopressin work?
Yes, in large controlled trials for its approved uses. The largest trial in the article had 237 women.
Desmopressin has been the standard treatment for central diabetes insipidus for nearly fifty years, and the nocturia indications were approved in 2017 and 2018 on randomized placebo-controlled trials summarized on their labels. The citations here are labels and regulatory records, not primary trial papers; the largest trial they describe is Nocdurna's three-month study in 237 women. 23
The DDAVP label describes controlled studies in central diabetes insipidus. They showed less urine output and more concentrated urine. It also describes studies in hemophilia A and von Willebrand disease. In those, factor VIII activity rose high enough for minor surgery. This held for patients whose baseline level is above 5%. 2
Nocdurna's approval rested on two randomized placebo-controlled trials. Each lasted three months. One enrolled 237 women and one enrolled 230 men. All woke at least twice a night to urinate. Both trials showed fewer night-time trips to the toilet than placebo. They also showed more nights with one trip or none. The gain over placebo was modest. The label sets different doses for men and women. Women are more prone to low sodium. 3
