Posterior pituitary hormones and

Posterior pituitary hormones

Diabetes insipidus

Vasopressin p. 669 (antidiuretic hormone, ADH) is used in

the treatment of pituitary (‘cranial’) diabetes insipidus as is its

analogue desmopressin p. 667. Dosage is tailored to produce

a slight diuresis every 24 hours to avoid water intoxication.

Treatment may be required for a limited period only in

diabetes insipidus following trauma or pituitary surgery.

Desmopressin is more potent and has a longer duration of

action than vasopressin; unlike vasopressin it has no

vasoconstrictor effect. It is given by mouth or intranasally

for maintenance therapy, and by injection in the

postoperative period or in unconscious patients.

Desmopressin is also used in the differential diagnosis of

diabetes insipidus. Following a dose intramuscularly or

intranasally, restoration of the ability to concentrate urine

after water deprivation confirms a diagnosis of cranial

diabetes insipidus. Failure to respond occurs in nephrogenic

diabetes insipidus.

In nephrogenic and partial pituitary diabetes insipidus

benefit may be gained from the paradoxical antidiuretic

effect of thiazides.

Carbamazepine p. 311 is sometimes useful in partial

pituitary diabetes insipidus [unlicensed]; it may act by

sensitising the renal tubules to the action of remaining

endogenous vasopressin.

Other uses

Desmopressin is also used to boost factor VIII concentration

in mild to moderate haemophilia and in von Willebrand’s

disease; it is also used to test fibrinolytic response.

Desmopressin may also have a role in nocturnal enuresis.

Vasopressin infusion is used to control variceal bleeding in

portal hypertension, prior to more definitive treatment and

with variable results. Terlipressin acetate, a derivative of

vasopressin with reportedly less pressor and antidiuretic

activity, is used similarly.

Oxytocin p. 823, another posterior pituitary hormone, is

indicated in obstetrics.

Antidiuretic hormone antagonists

Demeclocycline hydrochloride p. 564 can be used in the

treatment of hyponatraemia resulting from inappropriate

secretion of antidiuretic hormone, if fluid restriction alone

does not restore sodium concentration or is not tolerable.

Demeclocycline hydrochloride is thought to act by directly

blocking the renal tubular effect of antidiuretic hormone.

Tolvaptan p. 669 is a vasopressin V2-receptor antagonist

licensed for the treatment of hyponatraemia secondary to

syndrome of inappropriate antidiuretic hormone secretion;

treatment duration with tolvaptan is determined by the

underlying disease and its treatment.

Rapid correction of hyponatraemia during tolvaptan

therapy can cause osmotic demyelination, leading to serious

neurological events; close monitoring of serum sodium

concentration and fluid balance is essential.
