desonide 0.5 MG/ML Otic Solution

INDICATIONS AND USAGE Desonide Gel, 0.05% is indicated for the treatment of mild to moderate atopic dermatitis in patients 3 months of age and older. Patients should be instructed to use Desonide Gel, 0.05% for the minimum amount of time as necessary to achieve the desired results because of the potential for Desonide Gel, 0.05% to suppress the hypothalamicpituitary-adrenal (HPA) axis [see Warnings and Precautions ( 5.1 )]. Treatment should not exceed 4 consecutive weeks [see Dosage and Administration ( 2 )]. Desonide Gel, 0.05% is a corticosteroid indicated for the topical treatment of mild to moderate atopic dermatitis in patients 3 months of age and older. ( 1 )

DOSAGE AND ADMINISTRATION Apply a thin layer to the affected areas two times daily and rub in gently. Discontinue use when control is achieved. If no improvement is seen within 4 weeks, reassessment of diagnosis may be necessary. Treatment beyond 4 consecutive weeks is not recommended. Do not use with occlusive dressings. Avoid contact with eyes or other mucous membranes. For topical use only. Not for oral, ophthalmic, or intravaginal use. • Apply as a thin layer to the affected areas two times daily and rub in gently. ( 2 ) • Therapy should be discontinued when control is achieved. ( 2 ) • If no improvement is seen within 4 weeks, reassessment of diagnosis may be necessary. ( 2 ) • Should not be used with occlusive dressings. ( 2 ) • Treatment beyond 4 consecutive weeks is not recommended. ( 2 ) • For topical use only. Not for oral, ophthalmic, or intravaginal use. ( 2 )

WARNINGS AND PRECAUTIONS • Topical corticosteroids can produce reversible hypothalamic pituitary adrenal (HPA) axis suppression, Cushing’s syndrome and unmask latent diabetes. ( 5.1 ) • Systemic absorption may require evaluation for HPA axis suppression. ( 5.1 ) • Modify use should HPA axis suppression develop ( 5.1 ) • Potent corticosteroids, use on large areas, prolonged use or occlusive use may increase systemic absorption ( 5.1 ) • Local adverse reactions may include atrophy, striae, irritation, acneiform eruptions, hypopigmentation, and allergic contact dermatitis and may be more likely with occlusive use or more potent corticosteroids. ( 5.2 , 5.4 , 6 ) • Children may be more susceptible to systemic toxicity when treated with topical corticosteroids. ( 5.1 , 8.4 ) 5.1 Effects on Endocrine System Systemic absorption of topical corticosteroids can produce reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for clinical glucocorticosteroid insufficiency. This may occur during treatment or upon withdrawal of the topical corticosteroid. The effect of Desonide Gel, 0.05% on HPA axis function was investigated in pediatric subjects, 6 months to 6 years old, with atopic dermatitis covering at least 35% of their body, who were treated with Desonide Gel, 0.05% twice daily for 4 weeks. One of 37 subjects (3%) displayed adrenal suppression after 4 weeks of use, based on the cosyntropin stimulation test. As follow-up evaluation of the subject’s adrenal axis was not performed, it is unknown whether the suppression was reversible [see Use In Specific Populations ( 8.4 ) and Clinical Pharmacology ( 12.2 )]. Pediatric patients may be more susceptible than adults to systemic toxicity from equivalent doses of Desonide Gel, 0.05% due to their larger skin surface-to-body mass ratios [see Use In Specific Populations ( 8.4 )]. Because of the potential for systemic absorption, use of topical corticosteroids may require that patients be periodically evaluated for HPA axis suppression. Factors that predispose a patient using a topical corticosteroid to HPA axis suppression include the use of more potent steroids, use over large surface areas, use over prolonged periods, use under occlusion, use on an altered skin barrier, and use in patients with liver failure. An ACTH stimulation test may be helpful in evaluating patients for HPA axis suppression. If HPA axis suppression is documented, an attempt should be made to gradually withdraw the drug, to reduce the frequency of application, or to substitute a less potent steroid. Manifestations of adrenal insufficiency may require supplemental systemic corticosteroids. Recovery of HPA axis function is generally prompt and complete upon discontinuation of topical corticosteroids. Cushing’s syndrome, hyperglycemia, and unmasking of latent diabetes mellitus can also result from systemic absorption of topical corticosteroids. Use of more than one corticosteroid-containing product at the same time may increase the total systemic corticosteroid exposure. 5.2 Local Adverse Reactions with Topical Corticosteroids Local adverse reactions may be more likely to occur with occlusive use, prolonged use or use of higher potency corticosteroids. Reactions may include skin atrophy, striae, telangiectasias, burning, itching, irritation, dryness, folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, and miliaria. Some local adverse reactions may be irreversible. 5.3 Concomitant Skin Infections If concomitant skin infections are present or develop during treatment, an appropriate antifungal or antibacterial agent should be used. If a favorable response does not occur promptly, use of Desonide Gel, 0.05% should be discontinued until the infection is adequately controlled. 5.4 Skin Irritation If irritation develops, Desonide Gel, 0.05% 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.

CONTRAINDICATIONS Desonide Gel, 0.05% is contraindicated in those patients with a history of hypersensitivity to any of the components of the preparation. History of hypersensitivity to any of the components of the preparation.

CLINICAL PHARMACOLOGY Like other topical corticosteroids, desonide 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 . 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. Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease processes in the skin may increase percutaneous absorption. Studies performed with desonide cream, 0.05% and desonide ointment, 0.05% indicate that they are in the low range of potency as compared with other topical corticosteroids.
