Vasopressin Multifaceted Hormone Regulating Fluid Balance

In the treatment of central uremia, vasopressin is used to manage the symptoms associated with pressin deficiency, such as copious amounts of watery urine and increased thirst. It helps restore the balance of body fluid osmolality by increasing water reabsorption in the renal tubular collecting ducts, leading to a decrease in urine production and concentration of sodium in the urine.

Vasopressin is also utilized in the initial treatment of polyuria after brain surgery or head trauma. By regulating fluid balance, vasopressin assists in reducing excessive urine production and maintaining proper hydration.

Furthermore, vasopressin finds application in relaxing abdominal muscles when other drugs are ineffective. Its ability to induce vasoconstriction and affect smooth muscle contraction provides relief in certain conditions where muscle relaxation is required.
