Topical Use of Systemic Drugs in Dermatology: A Comprehensive Review

A user is seeking a pharmacy to compound a topical solution containing Minoxidil, Finasteride, Alfatradiol, Melatonin, Latanoprost, and either RU58841 or Pyrilutamide. They prefer a professional compounding lab over DIY methods.

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 topical treatment called 1961, containing multiple products, is discussed for its compatibility with finasteride. It is suggested that 1961 does not negatively affect finasteride's effectiveness and may even enhance its absorption.

The conversation is about making a topical solution from clascoterone powder, with references to using a RU58841 mixing guide for guidance. Concerns about product authenticity and bulk purchase requirements are also discussed.

The conversation is about obtaining custom-compounded topical finasteride in Germany due to side effects from oral finasteride. The user seeks a lower concentration solution separate from minoxidil, and others suggest self-mixing or trying alternatives like dutasteride.

Users discuss making topical finasteride solutions by dissolving crushed tablets in ethanol and propylene glycol, with concerns about residue affecting effectiveness. They also mention using minoxidil and oral finasteride, noting some hair regrowth and no side effects from topical use.
