Simultaneous Spectrophotometric Determination of Finasteride and Tadalafil in Recently FDA Approved Entadfi Capsules

The conversation discusses using very low dose topical finasteride to achieve specific serum DHT reduction percentages. It concludes that finasteride dosage increases linearly between 5-30% DHT reduction but requires exponential increases for reductions up to 70%.

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.

A Dutasteride Simulator predicts serum dutasteride, serum DHT, and scalp DHT levels using models from research papers. It simulates various dosing schedules to determine steady-state effects and visualizes outcomes, including hair growth-related scalp DHT suppression.

Switching from finasteride to a generic dutasteride led to unexpectedly high DHT levels, prompting a switch to a reputed brand and consideration of softgel capsules for better absorption. The user plans to retest DHT levels and may return to finasteride if issues persist.

Serum DHT levels and their variations when using dutasteride for hair loss treatment.

Topical dutasteride 0.05% is more effective for hair growth than oral finasteride 1mg, with minimal DHT reduction. The formulation uses castor oil and MCTs for better absorption but is not widely available until 2028.
