    Pharmacodynamics : Adapalene is a chemically stable retinoid-like compound. 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


  • Mechanism of action : Mechanistically, adapalene binds to specific retinoic acid nuclear receptors (gamma and beta) and retinoid X 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 may normalize the differentiation of

    follicular epithelial cells resulting in decreased microcomedone formation.

    Why is this medication prescribed? Adapalene is used to treat acne. Adapalene is in a class of medications called retinoid-like compounds. It works by stopping pimples from forming under the surface of

    the skin.

    How should this medicine be used? Adapalene comes as a gel, a solution (liquid), and a

    cream to apply to the skin. The solution comes in a glass bottle with an applicator and as individual pledgets

    (medicated wipes for one time use). It is usually applied once a day at bedtime. Follow the directions on your prescription label carefully, and ask your doctor or

    pharmacist to explain any part you do not understand. Apply adapalene exactly as directed. Do not apply more or less of it or apply it more often than prescribed by your doctor. Applying more adapalene or applying

    adaplene more often than recommended will not speed up or improve results, but it may irritate your skin.

    Adapalene controls acne but does not cure it. Your acne may get worse during the first few weeks of treatment, and it may take 8-12 weeks or longer before you feel the full benefit of adapalene. Pimples can take 6-8 weeks to form under the skin, and during the first weeks of your treatment, adapalene may bring these pimples to the skin surface. Continue to use adapalene even if your acne worsens or you do not see much improvement at first. Do not stop using adapalene without talking to

    your doctor. Do not apply adapalene to skin that is sunburned,

    broken, or covered with eczema (a skin disease). If you

  • have any of these conditions, do not apply adapalene until your skin has healed.

    Be careful not to get adapalene in your eyes, nose, or mouth. If you do get adapalene in your eyes, wash them with plenty of water and call your doctor. Your eyes may

    become irritated, swollen, or infected. To use the cream, gel, or solution, follow these steps: Gently wash the affected skin with a mild soap or

    soapless cleanser and pat dry with a soft towel. Do not use harsh or abrasive cleansers, and do not scrub your

    skin vigorously. Ask your doctor or pharmacist to recommend a gentle cleanser.

    If you are using the gel or cream, use your fingers to spread a thin film of medication over the affected area. If you are using a pledget, remove it from the foil pouch

    and gently wipe the entire affected area. If you are using the glass bottle of solution, apply a thin layer to the

    affected area using the applicator provided. You may feel a slight warmth or stinging in the place

    where you applied adapalene. This feeling is normal and should go away by itself in a short time.

    If you used a pledget, throw it away after use. Do not save it to use again.
