Development of a Doxazosin and Finasteride Transdermal System for Combination Therapy of Benign Prostatic Hyperplasia

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.

The conversation discusses the need for a localized 5-alpha reductase inhibitor that only affects the scalp without systemic side effects, similar to pyrilutamide's approach. Current treatments like topical liposomal finasteride and dutasteride are mentioned, but concerns about their systemic effects and lack of research are highlighted.

Topical androgen receptor antagonists may not be necessary if 5-AR inhibitors like finasteride or dutasteride effectively reduce DHT levels. Combining a 5-AR inhibitor with a topical androgen antagonist could potentially enhance treatment, but oral use of androgen antagonists is too risky due to severe side effects.

A 27-year-old male with Norwood grade 5 hair loss is using dutasteride and a hair serum with Redensyl, Anagain, Procapil, and Capilia Longa, but is hesitant to use oral minoxidil due to past allergic reactions to topical minoxidil. He plans to try dutasteride alone for 3 months before considering adding oral minoxidil.

The conversation discusses using Duodart (dutasteride + tamsulosin) for hair loss, with side effects like frequent urination and ejaculation issues leading to discontinuation. The user switched to German Avodart and experienced mood and erection side effects, considering adjusting the dosage to three times a week.

Switching to dutasteride as a hair loss prevention treatment, along with minoxidil, dermarolling and nizoral shampoo, and the potential benefits and side effects of using finasteride and/or dutasteride in combination with topical anti-androgens like RU58841.
