D-Pressin Nasal Spray 5 ml belongs to the class of 'antidiuretics', primarily used as replacement therapy in central cranial diabetes insipidus, a condition in which the body fails to control water balance, resulting in excessive urination. D-Pressin Nasal Spray 5 ml is also used to manage temporary polyuria (extreme urination) or polydipsia (extreme thirst) after head trauma or surgery in the pituitary gland.

D-Pressin Nasal Spray 5 ml contains Desmopressin, a human-made form (synthetic) of Vasopressin. Vasopressin is an antidiuretic (that controls fluid balance) hormone synthesized in the hypothalamus of the pituitary gland. When your body cannot produce enough vasopressin, D-Pressin Nasal Spray 5 ml is given to replace a low level of vasopressin. It mimics the natural hormone vasopressin and works by reabsorbing water from the kidneys, which controls excessive thirst and urination. Thus, it prevents dehydration.
