community Topical Finasteride with Chitosan: an overlooked solution?

in Finasteride/Dutasteride 5 upvotes 3 years ago

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.

community Are we underestimating systemic absorption with homemade/generic Topical Fin? (HPCH vs. PG/Ethanol formulations)

in Research/Science 5 upvotes 6 months ago

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.
