Desmopressin: What is it? Presentations, Dosage, Side Effects, Interactions and Preservation

It is an artificial medicine analogous to vasopressin.

Vasopressin is, in a general sense, the antidiuretic hormone by antonomasia of the human body because it is natural as long as the body itself produces or releases it by itself.

As a natural hormone, it is released by the pituitary gland and is known to work or activate by increasing the water permeability in renal tubular cells. This causes the urine volume to decrease significantly and, in parallel, increases urine concentration.

Precisely for these properties and faculties, in people with diabetes insipid or negligible due to trauma or surgery in the pituitary region of the brain, this medication would work very well to reduce frequent urination, as well as thirst or thirst sensation from the patients.

In a separate case, the FDA approved desmopressin in February 1978.
