Microencapsulation of Poorly Water-Soluble Finasteride in Polyvinyl Alcohol/Chitosan Microspheres as a Long-Term Sustained Release System for Potential Embolization Applications

Topical finasteride with hydroxypropyl chitosan shows significantly less serum absorption and minimal DHT reduction compared to oral finasteride. Users need the specific chitosan formulation to avoid side effects seen with regular ethanol+PG solutions.

Topical finasteride in a liposomal formulation reduces systemic absorption compared to ethanol solutions. The user is seeking sources for such products, noting that popular options like morr-f are not liposomal.

Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.

A peptide-based delivery system for finasteride shows promise in reducing systemic side effects while maintaining hair growth effectiveness. Combining this with other treatments like minoxidil and RU58841 could enhance results with lower systemic absorption.

A user is making a homemade topical finasteride solution by dissolving crushed finasteride tablets in ethanol and PG. They are unsure if the final solution maintains the intended concentration after filtering and are considering adding more ethanol to ensure accuracy.

The conversation is about using distilled water as a solvent for topical finasteride to reduce systemic absorption. The user is considering avoiding ethanol and propylene glycol to achieve this.
