Flumethasone: From Inflammatory Skin Conditions to Alopecia Areata
One-Sentence Summary
Flumethasone is a corticosteroid, originally used for inflammatory and immune-mediated skin conditions such as eczema, dermatitis and cutaneous lupus erythematosus. The TxGNN model predicts it may be effective for alopecia areata, but there are currently no registered clinical trials and no publications supporting this direction, so the prediction rests on the model alone.
Quick Overview
| Item | Content |
|---|---|
| Original Indication | Inflammatory skin conditions (e.g. atopic eczema, contact dermatitis, seborrhoeic dermatitis, discoid lupus erythematosus, primary cutaneous T-cell lymphoma); the licence records compiled for this report contain no indication text |
| Predicted New Indication | Alopecia areata |
| TxGNN Prediction Score | 99.93% |
| Evidence Level | L5 |
| UK Market Status | Marketed |
| Number of Marketing Authorisations | 2 |
| Recommended Decision | Hold |
Why is This Prediction Reasonable?
Currently, detailed mechanism of action data is not available. Based on known information, flumethasone is a corticosteroid, and its efficacy in inflammatory skin disease is established. Mechanistically, it may be applicable to alopecia areata.
Alopecia areata is an autoimmune, T-cell-mediated disease of the hair follicle. Topical and intralesional corticosteroids are an established therapy class for it, so a glucocorticoid anti-inflammatory and immunosuppressive effect is biologically plausible.
However, the very high score probably reflects similarity to other corticosteroids rather than flumethasone-specific data. No trial or literature data for flumethasone itself were available, so this remains a hypothesis.
Other predicted indications were considered, and none has supporting evidence:
- Alopecia mucinosa, Quinquaud’s folliculitis decalvans and primary cutaneous B-cell lymphoma have a plausible anti-inflammatory or lympholytic rationale, but only as adjunctive or symptomatic therapy.
- Telogen effluvium, hereditary hypotrichosis with recurrent skin vesicles, atrichia with papular lesions, and the rare syndromic alopecias (including alopecia with antibody deficiency, and alopecia with intellectual disability and hypergonadotropic hypogonadism) have little or no pharmacological rationale. In antibody deficiency, immunosuppression could be harmful.
- Alopecia universalis with onychodystrophy and vitiligo involves autoimmune components, but alopecia universalis responds poorly to topical steroids.
UK Market Information
| Marketing Authorisation Number | Product Name | Dosage Form | Approved Indication |
|---|---|---|---|
| 1201010F0BBAAAA | Locorten-Vioform Ear Drops | Ear drops (not specified in the data) | Not available |
| 1201010F0AAAAAA | Flumetasone/Clioquinol Ear Drops 0.02%/1% | Ear drops | Not available |
Both authorisations are valid single-ingredient records. The numbers above are as recorded in the data compiled for this report and are not in standard PL format. The products are ear preparations, so any use for scalp or skin conditions would be outside the marketed route and would need a route-compatibility assessment.
Safety Considerations
- Conditions flagged in the knowledge graph (not label text): The knowledge graph links flumethasone to contraindication-type associations with pituitary hormone deficiency and hypogonadotropic hypogonadism conditions, and with skin atrophy, telangiectasia, capillary disease and hereditary haemorrhagic telangiectasia. Skin atrophy is a recognised effect of topical corticosteroids and is relevant to any prolonged use on the scalp or skin. These associations need verification against the product label.
No drug interaction data were found.

Conclusion and Next Steps
Decision: Hold
Rationale: The prediction for alopecia areata is biologically plausible at the corticosteroid class level, but there are no flumethasone-specific trials or publications (Evidence Level L5). The only UK products are ear preparations, and the label-based safety information has not been obtained.
To proceed, the following is needed:
- Product label (SmPC) warnings and contraindications, which are required before safety screening can proceed
- Mechanism of action data for flumethasone
- A literature and trial search for flumethasone, or comparison with established topical corticosteroids, in alopecia areata
- Route and formulation assessment, since the marketed products are ear drops
- Verification of the knowledge-graph contraindication associations against the label
