Benign Prostatic Hyperplasia Pharmacotherapy And Incident Ocular Surface Disease: Comparative Risk Of Alpha-Blockers Vs 5-Alpha Reductase Inhibitors

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.

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

Androsterone may help with sexual and affective dysfunction from finasteride by replacing disrupted neurosteroids without increasing androgenic side effects. Controlled testing is needed to confirm its effectiveness and safety.

Woman uses antiandrogens for hair thinning prevention, experiences severe dry eye with finasteride. Asks if dutasteride could be better despite potential for worse dry eye.

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.

A 27-year-old male is experiencing a recurring pattern of hair loss after 5 months of using oral minoxidil and finasteride, despite initial success. He is considering using topical androgen receptor blockers like RU58841, pyrilutamide, or clascoterone to address potential androgen receptor hypersensitivity.
