Desmopressin uses


INDICATIONS AND USAGE:

Central Diabetes Insipidus:

Desmopressin tablets are indicated as antidiuretic replacement therapy in the management of central diabetes insipidus and for the management of the temporary polyuria and polydipsia following head trauma or surgery in the pituitary region. Desmopressin tablets are ineffective for the treatment of nephrogenic diabetes insipidus.

Patients were selected for therapy based on the diagnosis by means of the water deprivation test, the hypertonic saline infusion test, and/or response to antidiuretic hormone. Continued response to Desmopressin can be monitored by measuring urine volume and osmolality.

Primary Nocturnal Enuresis:

Desmopressin tablets are indicated for the management of primary nocturnal enuresis. Desmopressin tablets may be used alone or as an adjunct to behavioral conditioning or other non-pharmacologic intervention.

CONTRAINDICATIONS:

Desmopressin tablets are contraindicated in individuals with known hypersensitivity to Desmopressin or to any of the components of Desmopressin tablets.

Desmopressin is contraindicated in patients with moderate to severe renal impairment (defined as a creatinine clearance below 50ml/min).

Desmopressin is contraindicated in patients with hyponatremia or a history of hyponatremia.

WARNINGS:

Very rare cases of hyponatremia have been reported from world-wide postmarketing experience in patients treated with Desmopressin. Desmopressin is a potent antidiuretic which, when administered, may lead to water intoxication and/or hyponatremia. Unless properly diagnosed and treated hyponatremia can be fatal. Therefore, fluid restriction is recommended and should be discussed with the patient and/or guardian. Careful medical supervision is required.

When Desmopressin tablets are administered, in particular in pediatric and geriatric patients, fluid intake should be adjusted downward to decrease the potential occurrence of water intoxication and hyponatremia. (See PRECAUTIONS, Pediatric Use and Geriatric Use.) All patients receiving Desmopressin therapy should be observed for the following signs of symptoms associated with hyponatremia: headache, nausea/vomiting, decreased serum sodium, weight gain, restlessness, fatigue, lethargy, disorientation, depressed reflexes, loss of appetite, irritability, muscle weakness, muscle spasms or cramps and abnormal mental status such as hallucinations, decreased consciousness and confusion. Severe symptoms may include one or a combination of the following: seizure, coma and/or respiratory arrest. Particular attention should be paid to the possibility of the rare occurrence of an extreme decrease in plasma osmolality that may result in seizures which could lead to coma.

Desmopressin should be used with caution in patients with habitual or psychogenic polydipsia who may be more likely to drink excessive amounts of water, putting them at greater risk of hyponatremia.

PRECAUTIONS:

General:

Intranasal formulations of Desmopressin at high doses and Desmopressin injection have infrequently produced a slight elevation of blood pressure which disappears with a reduction of dosage. Although this effect has not been observed when single oral doses up to 0.6 mg have been administered, the drug should be used with caution in patients with coronary artery insufficiency and/or hypertensive cardiovascular disease, because of a possible rise in blood pressure.

Desmopressin should be used with caution in patients with conditions associated with fluid and electrolyte imbalance, such as cystic fibrosis, since these patients may develop hyponatremia.

Rare severe allergic reactions have been reported with Desmopressin. Anaphylaxis has been reported with intravenous and intranasal administration of Desmopressin, but not with Desmopressin tablets.

Laboratory Tests:

Central Diabetes Insipidus: Laboratory tests for monitoring the patient with central diabetes insipidus or post-surgical or head trauma-related polyuria and polydipsia include urine volume and osmolality. In some cases, measurements of plasma osmolality may be useful.

Drug Interactions:

Although the pressor activity of Desmopressin is very low compared to its antidiuretic activity, large doses of Desmopressin tablets should be used with other pressor agents only with careful patient monitoring.

Carcinogenicity, Mutagenicity, and Impairment of Fertility:

Studies with Desmopressin have not been performed to evaluate carcinogenic potential, mutagenic potential or effects on fertility.

Pregnancy:

Category B:

Fertility studies have not been done. Teratology studies in rats and rabbits at doses from 0.05 to 10 µg/kg/day revealed no harm to the fetus due to Desmopressin. There are, however, no adequate and well-controlled studies in pregnant women. Because animal studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.

Several publications where Desmopressin was used in the management of diabetes insipidus during pregnancy are available; these include a few anecdotal reports of congenital anomalies and low birth weight babies. However, no causal connection between these events and Desmopressin has been established. A fifteen year Swedish epidemiologic study of the use of Desmopressin in pregnant women with diabetes insipidus found the rate of birth defects to be no greater than that in the general population; however, the statistical power of this study is low. As opposed to preparations containing natural hormones, Desmopressin in antidiuretic doses has no uterotonic action and the physician will have to weigh the possible therapeutic advantages against the possible risks in each case.

Nursing Mothers:

There have been no controlled studies in nursing mothers. A single study in postpartum women demonstrated a marked change in plasma, but little if any change in assayable Desmopressin in breast milk following an intranasal dose of 0.01 mg.

It is not known whether the drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Desmopressin is administered to nursing mothers.

Pediatric Use:

Central Diabetes Insipidus: Desmopressin tablets have been used safely in pediatric patients, age 4 years and older, with diabetes insipidus for periods up to 44 months. In younger pediatric patients the dose must be individually adjusted in order to prevent an excessive decrease in plasma osmolality leading to hyponatremia and possible convulsions; dosing should start at 0.05 mg (1/2 of the 0.1 mg tablet). Use of Desmopressin in pediatric patients requires careful fluid intake restrictions to prevent possible hyponatremia and water intoxication.

Primary Nocturnal Enuresis: Desmopressin tablets have been safely used in pediatric patients age 6 years and older with primary nocturnal enuresis for up to 6 months. Some patients respond to a dose of 0.2 mg; however, increasing responses are seen at doses of 0.4 mg and 0.6 mg. No increase in the frequency or severity of adverse reactions or decrease in efficacy was seen with an increased dose or duration. The dose should be individually adjusted to achieve the best results.

ADVERSE REACTIONS:

Infrequently, large doses of the intranasal formulations of Desmopressin and Desmopressin injection have produced transient headache, nausea, flushing and mild abdominal cramps. These symptoms have disappeared with reduction in dosage.

Central Diabetes Insipidus:

In long-term clinical studies in which patients with diabetes insipidus were followed for periods up to 44 months of Desmopressin tablet therapy, transient increases in AST no higher than 1.5 times the upper limit of normal were occasionally observed. Elevated AST (SGOT) returned to the normal range despite continued use of Desmopressin tablets.

Primary Nocturnal Enuresis:

The only adverse event occurring in ≥ 3% of patients in controlled clinical trials with Desmopressin tablets that was probably, possibly, or remotely related to study drug was headache (4% Desmopressin, 3% placebo).

Other:

The following adverse events have been reported; however, their relationship to Desmopressin has not been established: abnormal thinking, diarrhea, and edema-weight gain.

OVERDOSAGE:

(See ADVERSE REACTIONS.) In case of overdose, the dose should be reduced, frequency of administration decreased, or the drug withdrawn according to the severity of the condition. There is no known specific antidote for Desmopressin. The patient should be observed and treated with appropriate symptomatic therapy.

An oral LD50 has not been established. Oral doses up to 0.2 mg/kg/day have been administered to dogs and rats for 6 months without any significant drug-related toxicities reported. An intravenous dose of 2 mg/kg in mice demonstrated no effect.

DOSAGE AND ADMINISTRATION:

Central Diabetes Insipidus:

The dosage of Desmopressin tablets must be determined for each individual patient and adjusted according to the diurnal pattern of response. Response should be estimated by two parameters: adequate duration of sleep and adequate, not excessive, water turnover. Patients previously on intranasal Desmopressin therapy should begin tablet therapy twelve hours after the last intranasal dose. During the initial dose titration period, patients should be observed closely and appropriate safety parameters measured to assure adequate response. Patients should be monitored at regular intervals during the course of Desmopressin tablets therapy to assure adequate antidiuretic response. Modifications in dosage regimen should be implemented as necessary to assure adequate water turnover. Fluid restriction should be observed.

Adults and Children: It is recommended that patients be started on doses of 0.05 mg (1/2 of the 0.1 mg tablet) two times a day and individually adjusted to their optimum therapeutic dose. Most patients in clinical trials found that the optimal dosage range is 0.1 mg to 0.8 mg daily, administered in divided doses. Each dose should be separately adjusted for an adequate diurnal rhythm of water turnover. Total daily dosage should be increased or decreased in the range of 0.1 mg to 1.2 mg divided into two or three daily doses as needed to obtain adequate antidiuresis. See Pediatric Use subsection for special considerations when administering Desmopressin to pediatric diabetes insipidus patients.

Geriatric Use:

This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. (See CLINICAL PHARMACOLOGY, Human Pharmacokinetics, CONTRAINDICATIONS, and PRECAUTIONS, Geriatric Use.)

Primary Nocturnal Enuresis:

The dosage of Desmopressin tablets must be determined for each individual patient and adjusted according to response. Patients previously on intranasal Desmopressin therapy can begin tablet therapy the night following (24 hours after) the last intranasal dose. The recommended initial dose for patients age 6 years and older is 0.2 mg at bedtime. The dose may be titrated up to 0.6 mg to achieve the desired response.
