Crisaborole

Introduction: What is Crisaborole?

Crisaborole is a topical medication primarily used to treat mild to moderate atopic dermatitis, commonly known as eczema. It is a nonsteroidal antiinflammatory drug (NSAID) that works by inhibiting specific pathways in the immune system, helping to reduce inflammation and alleviate symptoms associated with eczema. Approved by the FDA in 2016, Crisaborole is available in the form of an ointment and is designed for direct application to affected skin areas.

Uses of Crisaborole

Crisaborole is primarily indicated for the treatment of atopic dermatitis in patients aged two years and older. It is particularly beneficial for individuals who may not respond well to traditional treatments, such as topical corticosteroids, or for those who prefer to avoid steroids due to potential side effects. Crisaborole helps to relieve itching, redness, and inflammation associated with eczema, improving the overall quality of life for patients.

How It Works

Crisaborole functions by inhibiting the enzyme phosphodiesterase 4 (PDE4), which plays a crucial role in the inflammatory process. By blocking PDE4, Crisaborole increases the levels of cyclic adenosine monophosphate (cAMP) in immune cells. Elevated cAMP levels lead to a reduction in the release of proinflammatory cytokines, thereby decreasing inflammation and itching. In simpler terms, Crisaborole helps calm the skin's immune response, reducing the symptoms of eczema.

Dosage and Administration

Crisaborole is available as a 2% ointment. The standard dosage for adults and children aged two years and older is to apply a thin layer of the ointment to the affected areas of the skin twice daily. It is important to gently rub the ointment into the skin until it is fully absorbed. Patients should wash their hands after applying the medication, unless the hands are the treated area. It is essential to follow the prescribing physician's instructions regarding the duration of treatment.

Side Effects of Crisaborole

Common side effects of Crisaborole may include:

• Application site pain
• Burning or stinging sensation
• Itching
• Redness

Serious side effects are rare but can occur. Patients should seek medical attention if they experience:

• Severe allergic reactions (rash, itching, swelling)
• Signs of infection (fever, chills, persistent redness)

Drug Interactions

Crisaborole has a low potential for drug interactions due to its topical application and minimal systemic absorption. However, patients should inform their healthcare provider about all medications they are taking, including over-the-counter drugs and supplements. It is particularly important to discuss the use of other topical medications or treatments for eczema to avoid potential irritation or adverse effects.

Benefits of Crisaborole

Crisaborole offers several clinical and practical advantages:

• Nonsteroidal: Unlike traditional corticosteroids, Crisaborole does not carry the risk of skin thinning or other steroid-related side effects.
• Safe for long-term use: It can be used continuously without the same concerns associated with prolonged steroid use.
• Easy application: The ointment formulation allows for straightforward application to affected areas.
• Effective for sensitive skin: Crisaborole is suitable for use in sensitive areas of the body, such as the face and neck.

Contraindications of Crisaborole

Crisaborole should be avoided in individuals who have a known hypersensitivity to the drug or any of its components. Pregnant or breastfeeding women should consult their healthcare provider before using Crisaborole, as the effects on fetal development or nursing infants are not fully understood. Additionally, patients with severe liver disease should use Crisaborole with caution.

Precautions and Warnings

Before using Crisaborole, patients should inform their healthcare provider about any existing medical conditions, particularly skin infections or allergies. It is advisable to perform a patch test on a small skin area to check for any adverse reactions before applying it to larger areas. Regular follow-up appointments may be necessary to monitor the treatment's effectiveness and any potential side effects.
