Is flurandrenolide a steroid?
Yes, flurandrenolide is a topical corticosteroid, a synthetic steroid applied to the skin to alleviate redness, itching, swelling, and discomfort from various skin conditions. It requires a prescription and is available as a cream, ointment, lotion, and medicated tape. Brand names include Cordran, Cordran SP, and Cordran Tape.
How Flurandrenolide Works
Flurandrenolide's effectiveness stems from its anti-inflammatory, anti-itch (antipruritic), and blood vessel-narrowing (vasoconstrictive) properties. It reduces swelling, redness, and itching by activating natural skin substances and inhibiting the release of inflammatory chemicals like kinins, histamine, and prostaglandins. It also stabilizes cellular membranes, preventing the release of inflammation-causing enzymes. This action helps calm the skin's immune response.
Understanding Potency and Formulations
Topical steroid potency is categorized in classes from I (super potent) to VII (least potent). Flurandrenolide's strength varies by formulation:
- Cordran Tape (4 mcg/cm²): A very potent, Class I corticosteroid. The tape acts as an occlusive dressing, enhancing absorption and effectiveness, and is often used for dry, scaling, or hard-to-treat localized lesions.
- Cream, Ointment, and Lotion (0.05% and 0.025%): These forms generally have medium potency. The 0.05% ointment can sometimes be considered high-range, while the 0.05% cream is mid-range.
Conditions Treated with Flurandrenolide
Flurandrenolide is used for inflammatory and itchy skin conditions that respond to corticosteroids.
Flurandrenolide vs. Hydrocortisone: A Potency Comparison
Compared to milder hydrocortisone, flurandrenolide is significantly stronger. The table below shows the differences:
| Feature | Flurandrenolide | Hydrocortisone (1%) |
|---|---|---|
| Potency Class | Class I (Tape), Class IV/V (Cream/Ointment) | Class VII (Least Potent) |
| Strength | Very High to Medium | Low |
| Availability | Prescription-only | Over-the-counter and prescription |
| Common Use | Moderate to severe, localized dermatoses | Mild inflammatory skin conditions |
Side Effects and Important Precautions
Like all corticosteroids, flurandrenolide can cause side effects. Local reactions at the application site, such as burning, itching, irritation, or dryness, are common initially.
More severe systemic side effects can occur with prolonged use, high doses, extensive application areas, or use with occlusive dressings like the tape. These happen when the medication is absorbed into the bloodstream.
Potential Systemic Side Effects:
- HPA Axis Suppression: Absorption can suppress the HPA axis, affecting stress response and metabolism. Symptoms may include unusual tiredness, weight loss, and dizziness. Children are particularly susceptible.
- Cushing's Syndrome: Long-term high cortisol exposure can cause weight gain (especially in the face and upper back), skin thinning, and mood changes.
- Hyperglycemia: Blood sugar levels may increase.
Local Skin Side Effects (with long-term use):
- Skin thinning (atrophy)
- Stretch marks (striae)
- Acne-like breakouts
- Rash around the mouth (perioral dermatitis)
- Changes in skin color
It is vital to use flurandrenolide precisely as prescribed and only for the duration instructed by a physician. Avoid using it on the face, groin, or underarms unless specifically directed by a doctor.
Conclusion
Flurandrenolide is definitively a steroid, a potent topical corticosteroid used for inflammatory skin conditions. Its anti-inflammatory and anti-itch properties make it effective. However, its medium to very high potency requires medical supervision to minimize the risk of significant local and systemic side effects.
