CLINICAL PHARMACOLOGY
Like other topical corticosteroids, mometasone furoate has anti-inflammatory, antipruritic, and vasoconstrictive properties. The mechanism of the anti-inflammatory activity of the topical steroids, in general, is unclear. However, corticosteroids are thought to act by the induction of phospholipase A2 inhibitory proteins, collectively called lipocortins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A2.
Pharmacokinetics:
The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle and the integrity of the epidermal barrier. Occlusive dressings with hydrocortisone for up to 24 hours have not been demonstrated to increase penetration; however, occlusion of hydrocortisone for 96 hours markedly enhances penetration. Studies in humans indicate that approximately 0.7% of the applied dose of Mometasone Furoate, USP Ointment 0.1% enters the circulation after 8 hours of contact on normal skin without occlusion. Inflammation and/or other disease processes in the skin may increase percutaneous absorption.
Studies performed with Mometasone Furoate Ointment 0.1% indicate that it is in the medium range of potency as compared with other topical corticosteroids.
In a study evaluating the effects of mometasone furoate ointment on the hypothalamic-pituitary-adrenal (HPA) axis, 15 grams were applied twice daily for 7 days to six adult patients with psoriasis or atopic dermatitis. The ointment was applied without occlusion to at least 30% of the body surface. The results show that the drug caused a slight lowering of adrenal corticosteroid secretion.
In a pediatric trial, 24 atopic dermatitis patients, of which 19 patients were age 2 to 12 years, were treated with Mometasone Furoate Cream 0.1% once daily. The majority of patients cleared within 3 weeks.
Sixty-three pediatric patients ages 6 to 23 months, with atopic dermatitis, were enrolled in an open-label, hypothalamic-pituitary- adrenal (HPA) axis safety study. Mometasone Furoate, USP Ointment 0.1% was applied once daily for approximately 3 weeks over a mean body surface area of 39% (range 15% to 99%). In approximately 27% of patients who showed normal adrenal function by Cortrosyn test before starting treatment, adrenal suppression was observed at the end of treatment with Mometasone Furoate, USP Ointment 0.1%. The criteria for suppression were: basal cortisol level of ≤5 mcg/dL, 30-minute post-stimulation level of less than or equal to 18 mcg/dL, or an increase of less than 7 mcg/dL. Follow-up testing 2 to 4 weeks after stopping treatment, available for 8 of the patients, demonstrated suppressed HPA axis function in 3 patients, using these same criteria. -
INDICATIONS AND USAGE
Mometasone Furoate, USP Ointment 0.1% is a medium potency corticosteroid indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses.
Mometasone Furoate, USP Ointment 0.1% may be used in pediatric patients 2 years of age or older, although the safety and efficacy of drug use for longer than 3 weeks have not been established (see PRECAUTIONS – Pediatric Use section). Since safety and efficacy of Mometasone Furoate Ointment 0.1% have not been established in pediatric patients below 2 years of age, its use in this age group is not recommended.

PRECAUTIONS
Enter section text here
General:
Systemic absorption of topical corticosteroids can produce reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for glucocorticosteroid insufficiency after withdrawal of treatment. Manifestations of Cushing’s syndrome, hyperglycemia, and glucosuria can also be produced in some patients by systemic absorption of topical corticosteroids while on treatment.
Patients applying a topical steroid to a large surface area or to areas under occlusion should be evaluated periodically for evidence of HPA axis suppression. This may be done by using the ACTH stimulation, A.M. plasma cortisol, and urinary free cortisol tests.
In a study evaluating the effects of mometasone furoate ointment on the hypothalamic-pituitary-adrenal (HPA) axis, 15 grams were applied twice daily for 7 days to six adult patients with psoriasis or atopic dermatitis. The ointment was applied without occlusion to at least 30% of the body surface. The results show that the drug caused a slight lowering of adrenal corticosteroid secretion.
If HPA axis suppression is noted, an attempt should be made to withdraw the drug, to reduce the frequency of application, or to substitute a less potent corticosteroid. Recovery of HPA axis function is generally prompt upon discontinuation of topical corticosteroids. Infrequently, signs and symptoms of glucocorticosteroid insufficiency may occur requiring supplemental systemic corticosteroids. For information on systemic supplementation, see Prescribing Information for those products.
Pediatric patients may be more susceptible to systemic toxicity from equivalent doses due to their larger skin surface to body mass ratios (see PRECAUTIONS – Pediatric Use).
If irritation develops, Mometasone Furoate, USP Ointment 0.1% should be discontinued and appropriate therapy instituted. Allergic contact dermatitis with corticosteroids is usually diagnosed by observing a failure to heal rather than noting a clinical exacerbation as with most topical products not containing corticosteroids. Such an observation should be corroborated with appropriate diagnostic patch testing.
If concomitant skin infections are present or develop, an appropriate antifungal or antibacterial agent should be used. If a favorable response does not occur promptly, use of Mometasone Furoate, USP Ointment 0.1% should be discontinued until the infection has been adequately controlled.
Information for Patients
Patients using topical corticosteroids should receive the following information and instructions:
-
This medication is to be used as directed by the physician. It is for external use only. Avoid contact with the eyes.
-
This medication should not be used for any disorder other than that for which it was prescribed.
-
The treated skin area should not be bandaged or otherwise covered or wrapped so as to be occlusive, unless directed by the physician.
-
Patients should report to their physician any signs of local adverse reactions.
-
Parents of pediatric patients should be advised not to use Mometasone Furoate, USP Ointment 0.1% in the treatment of diaper dermatitis. Mometasone Furoate, USP Ointment 0.1% should not be applied in the diaper area as diapers or plastic pants may constitute occlusive dressing (see DOSAGE AND ADMINISTRATION).
-
This medication should not be used on the face, underarms, or groin areas unless directed by the physician.
-
As with other corticosteroids, therapy should be discontinued when control is achieved. If no improvement is seen within 2 weeks, contact the physician.
-
Other corticosteroid-containing products should not be used with Mometasone Furoate, USP Ointment 0.1% without first consulting with the physician.
Laboratory Tests
The following tests may be helpful in evaluating patients for HPA axis suppression:
ACTH stimulation test A.M. plasma cortisol test Urinary free cortisol testCarcinogenesis, Mutagenesis, Impairment of Fertility
Long-term animal studies have not been performed to evaluate the carcinogenic potential of Mometasone Furoate, USP Ointment 0.1%. Long-term carcinogenicity studies of mometasone furoate were conducted by the inhalation route in rats and mice. In a 2-year carcinogenicity study in Sprague-Dawley rats, mometasone furoate demonstrated no statistically significant increase of tumors at inhalation doses up to 67 mcg/kg (approximately 0.04 times the estimated maximum clinical topical dose from Mometasone Furoate Ointment 0.1% on a mcg/m2 basis). In a 19-month carcinogenicity study in Swiss CD-1 mice, mometasone furoate demonstrated no statistically significant increase in the incidence of tumors at inhalation doses up to 160 mcg/kg (approximately 0.05 times the estimated maximum clinical topical dose from Mometasone Furoate, USP Ointment 0.1% on a mcg/m2 basis).
Mometasone furoate increased chromosomal aberrations in an in vitro Chinese hamster ovary cell assay, but did not increase chromosomal aberrations in an in vitro Chinese hamster lung cell assay. Mometasone furoate was not mutagenic in the Ames test or mouse lymphoma assay, and was not clastogenic in an in vivo mouse micronucleus assay, a rat bone marrow chromosomal aberration assay, or a mouse male germ-cell chromosomal aberration assay. Mometasone furoate also did not induce unscheduled DNA synthesis in vivo in rat hepatocytes.
In reproductive studies in rats, impairment of fertility was not produced in male or female rats by subcutaneous doses up to 15 mcg/kg (approximately 0.01 times the estimated maximum clinical topical dose from Mometasone Furoate, USP Ointment 0.1% on a mcg/m2 basis).
Nursing Mothers
Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in human milk. Because many drugs are excreted in human milk, caution should be exercised when Mometasone Furoate, USP Ointment 0.1% is administered to a nursing woman.
Pediatric Use
Mometasone Furoate, USP Ointment 0.1% may be used with caution in pediatric patients 2 years of age or older, although the safety and efficacy of drug use for longer than 3 weeks have not been established. Use of Mometasone Furoate, USP Ointment 0.1% is supported by results from adequate and well controlled studies in pediatric patients with corticosteroid responsive dermatoses. Since safety and efficacy of Mometasone Furoate Ointment 0.1% have not been established in pediatric patients below 2 years of age, its use in this age group is not recommended.
Mometasone Furoate, USP Ointment 0.1% caused HPA axis suppression in approximately 27% of pediatric patients ages 6 to 23 months, who showed normal adrenal function by Cortrosyn test before starting treatment, and were treated for approximately 3 weeks over a mean body surface area of 39% (range 15% to 99%). The criteria for suppression were: basal cortisol level of less than or equal to 5 mcg/dL, 30-minute poststimulation level of less than or equal to 18 mcg/dL, or an increase of less than 7 mcg/dL. Follow-up testing 2 to 4 weeks after stopping treatment, available for 8 of the patients, demonstrated suppressed HPA axis function in 3 patients, using these same criteria. Long-term use of topical corticosteroids has not been studied in this population (see CLINICAL PHARMACOLOGY – Pharmacokinetics).
Because of a higher ratio of skin surface area to body mass, pediatric patients are at a greater risk than adults of HPA axis suppression and Cushing’s syndrome when they are treated with topical corticosteroids. They are, therefore, also at greater risk of adrenal insufficiency during and/or after withdrawal of treatment. Pediatric patients may be more susceptible than adults to skin atrophy, including striae, when they are treated with topical corticosteroids. Pediatric patients applying topical corticosteroids to greater than 20% of body surface are at higher risk of HPA axis suppression.
HPA axis suppression, Cushing’s syndrome, linear growth retardation, delayed weight gain, and intracranial hypertension have been reported in pediatric patients receiving topical corticosteroids. Manifestations of adrenal suppression in children include low plasma cortisol levels, and an absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema.
Mometasone Furoate, USP Ointment 0.1% should not be used in the treatment of diaper dermatitis.Geriatric Use
Clinical studies of Mometasone Furoate, USP Ointment 0.1% included 310 subjects who were 65 years of age and over and 57 subjects who were 75 years of age and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients. However, greater sensitivity of some older individuals cannot be ruled out.
