Pharmacology
Acne is a multifactorial skin condition characterized by excess sebum production, epithelial hyperkeratinization, proliferation of the skin commensal bacteria, and inflammation. Circulating and locally synthesized natural ligands, testosterone and dihydrotestosterone (DHT), serve as causative factors in both males and females. Upon binding of DHT, the DHT-androgen receptor complex dimerizes and translocates to the nucleus where it promotes the transcription of genes involved in acne pathogenesis, including proliferation and differentiation of sebocytes, excess sebum production, and inflammatory cytokine production. Clascoterone is a potent antagonist at ARs and competes for androgens in binding to the receptor, thereby inhibiting downstream signalling of ARs that promote acne.
Androgenetic alopecia is also an androgen-dependent and highly genetic condition. Dihydrotestosterone (DHT) binds to ARs expressed on dermal papilla cells (DPC) in the scalp to induce AR-mediated transcription of genes that contribute to androgenic alopecia. By blocking the interaction between DHT and aARs, clascoterone inhibits AR-regulated transcription and DHT-induced IL-6 synthesis.
Dosage & Administration
cream twice per day in the morning and evening to the affected area. Avoid accidental transfer of Clascoterone cream into eyes, mouth, or other mucous membranes. If contact with mucous membranes occurs, this should be rinsed thoroughly with water or as directed by physician.
Use in Children and Adolescents: Safety and effectiveness of Clascoterone cream for the topical treatment of acne vulgaris have not been established in pediatric patients under 12 years of age

Side Effects
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In two identical multicenter, randomized, double-blind, vehicle-controlled trials, 1421 subjects 12 years and older with facial acne vulgaris applied Winclas cream or vehicle twice daily for 12 weeks. Overall, 62% of the subjects were female, and 38% were male, 91% of the patients were Caucasian, and the mean age was 19.7 years.
Local skin reactions (edema, erythema/redness, pruritus, scaling/dryness, skin atrophy, stinging/burning, striae rubrea, telangiectasia) were observed during the 12-week treatment and occurred in a similar percentage of subjects treated with vehicle.
Pregnancy & Lactation
Precautions & Warnings
- Local Irritation: Pruritus, burning, skin redness or peeling may be experienced with Winclas cream. If these effects occur discontinue or reduce the frequency of application of Winclas cream.
- Hypothalamic-pituitary-adrenal (HPA) axis suppression may occur during or after treatment with Winclas.
- Paediatric patients may be more susceptible to systemic toxicity.
- Hyperkalemia: Elevated potassium levels are observed in some subjects during the clinical trials
