INDICATIONS AND USAGE Adapalene Cream, 0.1% is indicated for the topical treatment of acne vulgaris.

DOSAGE AND ADMINISTRATION Adapalene Cream, 0.1% should be applied to affected areas of the skin, once daily at nighttime. A thin film of the cream should be applied to the skin areas where acne lesions appear, using enough to cover the entire affected areas lightly. A mild transitory sensation of warmth or slight stinging may occur shortly after the application of Adapalene Cream, 0.1%.

ADVERSE REACTIONS In controlled clinical trials, local cutaneous irritation was monitored in 285 acne patients who used Adapalene Cream, 0.1% once daily for 12 weeks. The frequency and severity of erythema, scaling, dryness, pruritus and burning were assessed during these studies. The incidence of local cutaneous irritation with Adapalene Cream, 0.1% from the controlled clinical studies is provided in the following table: Incidence of Local Cutaneous Irritation with Adapalene Cream, 0.1% from Controlled Clinical Studies (N=285) None Mild Moderate Severe Erythema 52% (148) 38% (108) 10% (28) ‹1% (1) Scaling 58% (166) 35% (100) 6% (18) ‹1% (1) Dryness 48% (136) 42% (121) 9% (26) ‹1% (2) Pruritus (persistent) 74% (211) 21% (61) 4% (12) ‹1% (1) Burning/Stinging (persistent) 71% (202) 24% (69) 4% (12) ‹1% (2) Other reported local cutaneous adverse events in patients who used Adapalene Cream, 0.1% once daily included: sunburn (2%), skin discomfort-burning and stinging (1%) and skin irritation (1%). Events occurring in less than 1% of patients treated with Adapalene Cream, 0.1% included: acne flare, dermatitis and contact dermatitis, eyelid edema, conjunctivitis, erythema, pruritus, skin discoloration, rash, and eczema.

Drug Interactions As Adapalene Cream, 0.1% has the potential to produce local irritation in some patients, concomitant use of other potentially irritating topical products (medicated or abrasive soaps and cleansers, soaps and cosmetics that have a strong drying effect, and products with high concentrations of alcohol, astringents, spices or lime rind) should be approached with caution. Particular caution should be exercised in using preparations containing sulfur, resorcinol, or salicylic acid in combination with Adapalene Cream, 0.1%. If these preparations have been used, it is advisable not to start therapy with Adapalene Cream, 0.1% until the effects of such preparations in the skin have subsided.

Mechanism of Action: Adapalene acts on retinoid receptors. Biochemical and pharmacological profile studies have demonstrated that adapalene is a modulator of cellular differentiation, keratinization, and inflammatory processes all of which represent important features in the pathology of acne vulgaris. Mechanistically, adapalene binds to specific retinoic acid nuclear receptors but does not bind to the cytosolic receptor protein. Although the exact mode of action of adapalene is unknown, it is suggested that topical adapalene normalizes the differentiation of follicular epithelial cells resulting in decreased microcomedone formation.
