Description:
Crisaborole is a topical medication that is utilized primarily in the treatment of atopic dermatitis, also known as eczema. It is classified as a non-steroidal phosphodiesterase 4 (PDE4) inhibitor, which works by modulating the inflammatory response in the skin.
Mechanism of Action
Crisaborole inhibits the enzyme phosphodiesterase 4, leading to an increase in intracellular levels of cyclic adenosine monophosphate (cAMP). Elevated levels of cAMP help to reduce inflammation by suppressing the production of pro-inflammatory cytokines and mediators in the skin. This action contributes to the reduction of symptoms such as itching, redness, and swelling associated with atopic dermatitis.
Indications
Crisaborole is specifically indicated for:
Atopic Dermatitis: Crisaborole is used for the topical treatment of mild to moderate atopic dermatitis in patients aged 2 years and older. It is suitable for use in various anatomical locations, including sensitive areas like the face and neck.
Administration
Crisaborole is formulated as a 2% ointment and is applied topically to the affected areas of the skin. Patients are typically advised to apply a thin layer of the ointment to the affected skin areas twice daily. It's important to wash hands before and after applying the medication and to avoid using occlusive dressings unless instructed by a healthcare provider.
Side Effects
Common side effects of crisaborole may include:
Application Site Reactions: This can manifest as pain, itching, or erythema (redness) at the site of application.
Headache: Some patients may experience headaches, although this is generally less common.
Serious side effects are rare, but any signs of an allergic reaction should prompt immediate medical attention.
Contraindications and Precautions
Crisaborole is generally well-tolerated, but it should not be used in individuals with a known hypersensitivity to crisaborole or any components of the formulation.
Precautions:
Avoid Eyes and Mouth: Patients should avoid getting crisaborole in their eyes or mouth, and it should not be applied to infected skin.
Pregnancy and Breastfeeding: While there are no well-defined contraindications, it's essential for pregnant or breastfeeding women to discuss the use of crisaborole with their healthcare provider.
Conclusion
Crisaborole is an effective non-steroidal treatment option for managing mild to moderate atopic dermatitis in adults and children as young as 2 years old. Its mechanism of action targets the underlying inflammation associated with the condition, providing relief from symptoms without the risks associated with topical corticosteroids. As always, patients should follow their healthcare provider's instructions and report any concerning side effects or lack of improvement during treatment.
