Introduction
- Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by dry, itchy, inflamed skin.
- Flare-ups can be triggered by allergens, irritants, or stress.
- Medicines for eczema aim to reduce inflammation, control itching, and manage flare-ups.
Types of Medicines for Eczema
1. Topical Corticosteroids
- Examples: Hydrocortisone, Betamethasone, Mometasone, Clobetasol.
- Mechanism: Reduce inflammation and itching by suppressing the immune response.
- Use: First-line treatment for mild to severe eczema.
- Forms: Creams, ointments, lotions.
2. Topical Calcineurin Inhibitors
- Examples: Tacrolimus (Protopic), Pimecrolimus (Elidel).
- Mechanism: Suppress the immune system to reduce inflammation.
- Use: Second-line treatment for moderate to severe eczema, especially on sensitive areas like the face.
3. Topical PDE-4 Inhibitors
- Example: Crisaborole (Eucrisa).
- Mechanism: Reduces inflammation by inhibiting the PDE-4 enzyme.
- Use: Mild to moderate eczema.
4. Antihistamines
- Examples: Loratadine, Cetirizine, Diphenhydramine.
- Mechanism: Block histamine to reduce itching.
- Use: Provide symptomatic relief from itching, especially at night.
5. Systemic Corticosteroids
- Examples: Prednisone, Methylprednisolone.
- Mechanism: Suppress inflammation throughout the body.
- Use: Severe eczema flare-ups; short-term use only due to side effects.
6. Biologic Therapies
- Example: Dupilumab (Dupixent).
- Mechanism: Targets specific immune pathways (IL-4 and IL-13) to reduce inflammation.
- Use: Moderate to severe eczema unresponsive to topical treatments.
7. Immunosuppressants
- Examples: Cyclosporine, Methotrexate, Azathioprine.
- Mechanism: Suppress the immune system to reduce severe eczema.
- Use: For patients with chronic severe eczema unresponsive to other therapies.
8. Antibiotics
- Examples: Cephalexin, Doxycycline.
- Use: Treat secondary bacterial infections during eczema flare-ups.
9. Antifungals
- Examples: Ketoconazole, Terbinafine.
- Use: For eczema complicated by fungal infections.
10. Moisturizers and Emollients
- Examples: Petroleum jelly, Ceramide-based creams.
- Mechanism: Hydrate and protect the skin barrier.
- Use: Daily maintenance to prevent flare-ups.
