Desmopressin is a synthetic hormone that mimics the action of the natural antidiuretic hormone produced by the pituitary gland. It belongs to a class of medicines known as antidiuretic agents and is used to help the body retain water when that ability is impaired. In the UK, desmopressin is the active ingredient in products such as DDAVP and Nocdurna.
A few branded medicines contain desmopressin, each offered in slightly different forms.
Both brands are manufactured under licence and approved by the MHRA. The tablets come in 0.1 mg and 0.2 mg strengths, while the nasal sprays deliver a measured dose per actuation.
