Finasteride Induces Epigenetic Alteration of TMPRSS2 Gene Expression: A Potential Role in Severe Acute Respiratory Syndrome Coronavirus 2 Inhibition

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.

Dutasteride reduces DHT more effectively than finasteride, but finasteride is more commonly used and approved for hair loss. Users have mixed opinions on dutasteride's effectiveness, with some experiencing better results and others facing side effects or no improvement.

Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.

Dutasteride may not effectively stop scalp hair loss and can cause thinning of facial and body hair, including eyebrows. Users suggest considering other causes like autoimmune conditions or vitamin deficiencies and exploring treatments like finasteride or minoxidil.

A 15-year-old is concerned about hair loss, possibly at Norwood 2 or 3, and is using shampoos and conditioners recommended by a trichologist. Suggestions include considering topical minoxidil and consulting a doctor about topical anti-DHT treatments like finasteride or RU58841, but avoiding 5-alpha-reductase inhibitors at this age.

Finasteride can impact neurosteroids, potentially causing depression and other side effects in some users. Despite these concerns, many continue using it for hair loss, with some switching to topical applications to mitigate side effects.
