Application of Polarizable Continuum Modeling to Assess Minoxidil Solubility in Mixed Solvents

A minoxidil solution with only ethanol and minoxidil may not be properly absorbed without additional ingredients like propylene glycol or vegetable glycerin. It's suggested to use a reputable brand and test the product for authenticity.

RU-58841 does not dissolve well in common Minoxidil solutions due to water content, requiring a 70/30 ethanol/propylene glycol mix. Users report using separate solutions for RU-58841 and finasteride/Minoxidil for better results.

A user discusses their experience with dissolving high concentrations of minoxidil in various ethanol/PG ratios and mentions difficulties with combining it with RU58841. They note that a 5% minoxidil solution remains stable, while higher concentrations tend to precipitate.

The conversation discusses two methods for making topical finasteride: using ethanol and propylene glycol or mixing it with topical minoxidil. The focus is on solubility and absorption, with a suggestion to crush pills finely and possibly mix with minoxidil at a slightly elevated temperature.

Minoxidil can be used with isopropyl alcohol to create topical spironolactone. Spironolactone may dissolve better in ethanol or propylene glycol.

The conversation is about the effectiveness of Minoxidil formulations with different alcohol and propylene glycol (pg) ratios. The user finds that a formulation with 20% pg and 80% ethanol dries faster but is concerned about absorption time.
