1. Introduction to Minirin Nasal Spray
Overview of Minirin Nasal Spray
Minirin Nasal Spray is a man-made version of a hormone called vasopressin, which occurs naturally in the body.

3. How Minirin Works: Understanding the Mechanism
Pharmacodynamics of Desmopressin
Desmopressin acts like vasopressin by attaching to V2 receptors in the kidney tubules. This attachment sets off a series of processes that result in water channels being added to the tubular space making it easier for water to be reabsorbed.
How Desmopressin Affects the Body
