CLINICAL RATIONALE

Atopic Dermatitis

Atopic dermatitis is a chronic, pruritic, inflammatory skin disease. Clinical features include skin dryness, erythema, oozing and crusting, and lichenification. Pruritus is responsible for much of the disease burden for patients. The goals of treatment are to reduce symptoms of pruritus and dermatitis, prevent exacerbations, and minimize therapeutic risks.(4) Initial nonpharmacological therapy for atopic dermatitis, as recommended by American Academy of Dermatology (AAD) guidelines, is avoidance of soaps with alkaline pH and use of moisturizing agents. Recommended topical therapy for atopic dermatitis, indicated when nonpharmacologic interventions have failed, includes topical corticosteroids (TCS) and topical calcineurin inhibitors (TCI).(6,7) Proactive, once to twice weekly application of mid-potency TCS for up to 40 weeks has not demonstrated adverse events in clinical trials. AAD notes that mid- to higher-potency topical corticosteroids are appropriate for short courses to gain rapid control of symptoms, but long-term management should use the least-potent corticosteroid that is effective. TCIs (e.g., pimecrolimus, tacrolimus) are recommended by the AAD as second-line therapy, and are particularly useful in selected clinical situations such as recalcitrance to steroids; for sensitive areas (face, anogenital, skin folds); for steroid-induced atrophy; and when there is long-term uninterrupted topical steroid use.(6) Prescribing information for Elidel® (pimecrolimus) cream and Protopic® (tacrolimus) ointment indicate evaluation after 6 weeks if symptoms of atopic dermatitis do not improve.(9,10) While topical doxepin does provide short-term decrease in pruritus, it is not recommended for atopic dermatitis by the AAD guidelines due to the risk of absorption and contact dermatitis.(6)

Lichen Simplex Chronicus

Lichen simplex chronicus is a form of chronic neurodermatitis that presents as dry, patchy areas of skin that are scaly and thick.(5,8) The root of the disorder may be both a primary symptom reflective of a psychological component, or secondary to other cutaneous issues such as eczema or psoriasis. (8) Patients typically complain of intense pruritus in the affected areas. (8) The treatment of lichen simplex chronicus centers on the discontinuation of the itch/scratch cycle. Topical corticosteroids and topical emollients are commonly used therapies.(5,8) Efficacy of topical calcineurin inhibitors for unresponsive patients has been cited by some studies. Doxepin is also an option for local treatment of pruritis.(8)
