Abstract: BACKGROUND: Alopecia is a chronic dermatological disorder affecting men and women worldwide. Given the high incidence and significant impact on patients' well-being, options for managing and treating alopecia are essential. Topical available options remain limited and oral products may result in adverse effects. TrichoFoam™ is a ready-to-use foaming vehicle developed for compounding pharmacies and formulated with gentle, non-irritating, and sensory-pleasant ingredients. OBJECTIVE: The purpose of this study was to assess topical foams' physicochemical and microbiological stabilities of formulations compounded with TrichoFoam™ as the ready-touse vehicle. METHODS: HPLC analyses were conducted in a bracketed study covering concentrations of 0.1% to 2.0% of caffeine, 0.01% to 0.1% of clobetasol propionate, 0.1% to 0.25% of dutasteride, 0.25% to 0.50% of nicotinamide, and 0.25% to 2.5% of progesterone compounded with TrichoFoam™. Antimicrobial Effectiveness Testing was conducted at the beginning and end of the studies. RESULTS: Most formulations presented a beyond-use date of at least 90-180 days, except for clobetasol propionate, which showed compatibility for 14 days, and dutasteride 0.25%, which showed a BUD of 30 days. CONCLUSION: This validates the stability of the active pharmaceutical ingredients from different pharmacological classes with TrichoFoam™, suggesting that this ready-to-use vehicle can be an excellent alternative for personalized alopecia treatment.
