Reference Label Set Id: Clobetasol propionate gel, cream and ointment contain the active compound clobetasol propionate, a synthetic corticosteroid, for topical dermatologic use. Clobetasol, an analog of prednisolone, has a high degree of glucocorticoid activity and a slight degree of mineralocorticoid activity. Clobetasol propionate is a white to cream-colored crystalline powder insoluble in water.
Each gram of the 0. Like other topical corticosteroids, clobetasol propionate 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 A 2 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 A 2. 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 has not been demonstrated to increase penetration; however, occlusion of hydrocortisone for 96 hours markedly enhances penetration. Topical corticosteroids can be absorbed from normal intact skin. Greater absorption was observed for the clobetasol propionate gel formulation as compared to the cream formulation in in vitro human skin penetration studies.
Studies performed with clobetasol propionate gel, cream and ointment indicate that they are in the super-high range of potency as compared with other topical corticosteroids. Clobetasol propionate gel, cream and ointment are super-high potency corticosteroid formulations indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid responsive dermatoses.
Treatment beyond 2 consecutive weeks is not recommended, and the total dosage should not exceed 50 g per week because of the potential for the drug to suppress the hypothalamic-pituitary-adrenal HPA axis.
Use in pediatric patients under 12 years of age is not recommended. As with other highly active corticosteroids, therapy should be discontinued when control has been achieved. If no improvement is seen within 2 weeks, reassessment of the diagnosis may be necessary. Clobetasol propionate gel, cream and ointment are contraindicated in those patients with a history of hypersensitivity to any of the components of the preparations.
Clobetasol propionate is a highly potent topical corticosteroid that has been shown to suppress the HPA axis at doses as low as 2 g per day. Systemic absorption of topical corticosteroids can produce reversible HPA axis suppression with the potential for glucocorticosteroid insufficiency after withdrawal from treatment. Manifestations of Cushing's syndrome, hyperglycemia, and glucosuria can also be produced in some patients by systemic absorption of topical corticosteroids while on therapy.
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. Patients receiving superpotent corticosteroids should not be treated for more than 2 weeks at a time and only small areas should be treated at any one time due to the increased risk of HPA suppression.
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. If irritation develops, clobetasol propionate should be discontinued and appropriate therapy instituted.
Allergic contact dermatitis with corticosteroids is usually diagnosed by observing 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 clobetasol propionate should be discontinued until the infection has been adequately controlled. Clobetasol propionate gel, cream, and ointment should not be used in the treatment of rosacea or perioral dermatitis and it should not be used on the face, groin, or axillae.
Patients using topical corticosteroids should receive the following information and instructions:. The following tests may be helpful in evaluating patients for HPA axis suppression: ACTH stimulation test, A.
Long-term animal studies have not been performed to evaluate the carcinogenic potential of clobetasol propionate. Clobetasol propionate was non-mutagenic in three different test systems: Corticosteroids have been shown to be teratogenic in laboratory animals when administered systemically at relatively low dosage levels. Some corticosteroids have been shown to be teratogenic after dermal application to laboratory animals. Clobetasol propionate has not been tested for teratogenicity when applied topically; however, it is absorbed percutaneously, and when administered subcutaneously it was a significant teratogen in both the rabbit and mouse.
Clobetasol propionate has greater teratogenic potential than steroids that are less potent. These doses are approximately 1.
Abnormalities seen included cleft palate and skeletal abnormalities. These doses are approximately 0. Abnormalities seen included cleft palate, cranioschisis, and other skeletal abnormalities.
There are no adequate and well-controlled studies of the teratogenic potential of clobetasol propionate in pregnant women. Clobetasol propionate gel, cream or ointment should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
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 either clobetasol propionate gel, cream or ointment is administered to a nursing woman. Safety and effectiveness of clobetasol propionate gel, cream, and ointment in pediatric patients have not been established. Use in children under 12 years of age is not recommended. 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 or after withdrawal of treatment. HPA axis suppression, Cushing's syndrome, linear growth retardation, delayed weight gain and intracranial hypertension have been reported in children 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. Clinical studies of clobetasol propionate drug products in US clinical trials did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.
In general, dose selection for an elderly patient should be cautious. In a controlled clinical trial with clobetasol propionate gel, the only reported adverse reaction that was considered to be drug related was a report of burning sensation 1.
Less frequent adverse reactions were itching, skin atrophy, and cracking and fissuring of the skin. In controlled clinical trials, the most frequent adverse events reported for clobetasol propionate ointment were burning sensation, irritation, and itching in 0.
Less frequent adverse reactions were stinging, cracking, erythema, folliculitis, numbness of fingers, skin atrophy, and telangiectasia. Cushing's syndrome has been reported in infants and adults as a result of prolonged use of topical clobetasol propionate formulations. The following additional local adverse reactions have been reported with topical corticosteroids, and they may occur more frequently with the use of occlusive dressings and higher potency corticosteroids.
These reactions are listed in an approximately decreasing order of occurrence: Apply a thin layer of clobetasol propionate gel, cream or ointment to the affected skin areas twice daily and rub in gently and completely.
Clobetasol propionate gel, cream and ointment are super-high potency topical corticosteroids; therefore, treatment should be limited to 2 consecutive weeks, and amounts greater than 50 g per week should not be used. If no improvement is seen within 2 weeks, reassessment of diagnosis may be necessary. Clobetasol propionate gel, cream or ointment should not be used with occlusive dressings. Pharmacokinetics The extent of percutaneous absorption of topical corticosteroids is determined by many factors, including the vehicle and the integrity of the epidermal barrier.
