Development of Stable and Simple Finasteride 333-μg/mL Suspensions That Minimize Occupational Exposure

The conversation discusses a topical finasteride therapy with hydrocortisone butyrate, estrone base, and breviline. A user suggests oral finasteride as a superior option.

The conversation discusses enhancing a 1% topical finasteride solution for hair retention and regrowth with additional ingredients like melatonin, caffeine, and adenosine, while considering stability and efficacy. Concerns are raised about the stability of topical finasteride, with suggestions to use oral finasteride or obtain fresh formulations from a trusted pharmacy.

A user stopped finasteride after 15 years due to severe side effects, which improved after quitting. They maintained most of their hair and are considering alternatives like topical treatments or RU58841.

The conversation discusses using Rogain foam as a solvent for topical finasteride due to an allergy to propylene glycol. The foam's ingredients, including alcohol SD 40B, are considered suitable for dissolving finasteride for easier application without skin irritation.

The user has been mixing finasteride with stemoxydine for hair loss and is considering switching to a less expensive product with a different ingredient list. They are questioning if the new product's higher water content compared to alcohol will affect the finasteride's solubility.

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.
