Female considering adding topical anti-androgen, seeks advice on RU58841 or pyrilutamid's binding affinity compared to spironolactone.

New hair loss treatments PP405 and VDPHL01 are discussed with skepticism and hope, alongside existing treatments like minoxidil and finasteride. Users express frustration over limited progress since the 1980s but remain cautiously optimistic.

PP405 shows initial promise for treating androgenetic alopecia, with safety confirmed in early trials, but skepticism remains due to limited data. Further trials are needed to determine its true efficacy and potential market impact.

RU58841, an anti-androgenic compound, showed early promise for treating alopecia but faced challenges after its patent in 1997. Despite advancing to Phase II trials, safety concerns and financial struggles led Aventis to abandon its development. Proskelia, which later merged into ProStrakan, couldn't prioritize the drug, leading to its eventual stagnation and failure to reach the market.

Pyrilutamide is a selective AR antagonist with a high binding affinity, making it effective in competing with DHT for androgen receptors. The 1% concentration is more effective than the 0.5%, but the latter may suffice for mild hair loss; the drug is considered a good option for those avoiding 5AR blockers due to side effects.

RU58841 lacks FDA approval due to financial and safety concerns, including potential cardiological side effects. The company abandoned further research, and users report adverse effects like heart palpitations and gynecomastia.

The conversation discusses the potential benefits of adding Vitamin B6 (P-5-P) to topical hair loss treatments like RU58841, finasteride, or minoxidil. The user suggests that Vitamin B6 might enhance these treatments by naturally lowering scalp prolactin.

P-1075 is a more potent hair growth agent than Minoxidil, but it poses significant heart risks, making it unsafe for use. Despite promising results in macaques, concerns about its cardiotoxicity in rats have halted its development.

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.

The user is applying topical finasteride with stemoxydine for hair loss and has noticed hair thickening but no regrowth after two months. They also report high SHBG and prolactin levels and a lack of morning erections, even on low doses of medication.

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.

Hair loss treatments, specifically about the effectiveness of RU58841 compared to Pyrilutamide. Molecular weights and side effects were discussed in terms of efficacy and cost-effectiveness.

Hmi115, a prolactin receptor blocker, showed promise for hair growth, but results from Phase 2 trials have not been published. ABS-201, an AI-based analog, is expected to begin trials in December 2025, while commercialization of treatments like PP-405 is anticipated around 2027.

The FDA policy change may speed up approval for hair loss drugs like PP405, VDPHL-01, and Breezula by potentially eliminating the need for a second confirmatory Phase 3 trial. Approval timelines could be as early as 2028 for some treatments if Phase 3 results are strong.

PP405 shows promise for hair follicle reactivation with minimal side effects. Users recommend continuing Minoxidil and Finasteride until more results are confirmed.

Pyrilutamide is believed to be more effective than RU58841 and 1 mg finasteride in treating hair loss, with no systemic hormonal effects and the potential to block more than 31% of scalp DHT. It may also antagonize scalp testosterone due to its action as an androgen receptor antagonist.

Oral PTD-DBM was discussed as a potential hair loss treatment, but it was deemed ineffective in humans despite promising results in mice. The conversation concluded that trying it without VPA might be unwise.

The conversation is about comparing the effectiveness of fluridil and clascoterone in preventing hair loss and inquiring about their use as standalone treatments. There is a question about the concentration of the fluridil brand for efficacy.

PP405 is a new drug in Phase 2 trials for hair loss, generating cautious optimism among users. Some users are currently using finasteride and experiencing side effects, while others are skeptical about unapproved products being sold.

The efficacy of degrading the androgen receptor through dermal application in DP cells, a delivery system for topical drugs that involves dissolving microneedles, and rosemary oil as an alternative anti-androgen.

PP405 is a potential hair loss treatment showing promise, especially for men with severe balding. Some are hopeful it will be a game-changer for those who cannot tolerate finasteride or minoxidil, despite skepticism about the outcomes.

The user experienced a decrease in libido after long-term use of Finasteride and wonders if it's related to the medication. Responses suggest that hormonal changes and libido fluctuations are normal and may not be solely due to Finasteride.

The FDA will now require only one clinical trial for drug approval, potentially speeding up the release of hair loss treatments like PP405. Pelage is expected to present full results of PP405 Phase 2a trials and move to Phase III in mid-2026.

The safety of combining alfatradiol and fluridil with finasteride as a potential treatment for male pattern baldness, which is approved in the European Union. Other treatments such as minoxidil and RU58841 were also discussed.

RU58841, a potential hair loss treatment, was not commercialized due to marketability issues and lack of long-term safety data. Concerns about its formulation and delivery methods further complicate its use.

The potential accuracy and trustworthiness of websites selling Pyrilutamide, a drug related to hair loss treatments such as Minoxidil, Finasteride, and RU58841; and whether Pyrilutamide is four times stronger than RU58841.

Clascoterone in Winlevi, a topical AR antagonist, is being re-examined due to concerns about HPA axis suppression in adolescents, but it's unlikely to be banned for adult use in androgenetic alopecia (AGA). The European Medicines Agency recommended refusing Winlevi for acne vulgaris, but this may not affect Breezula's approval for AGA.

Hope Medicine's HMI-115 is expected to be released in 2027, with phase 3 trials currently recruiting. Concerns include the safety of targeting prolactin and the potential cost of the treatment.

Finasteride's effectiveness and side effects may vary based on male phenotypes, with some users noting differences in response related to body and facial hair characteristics. Some users report success with lower doses, while others experience side effects, suggesting individual variability in response to the treatment.

The conversation discusses hair loss treatments, focusing on a new slow-release oral minoxidil compared to topical minoxidil and finasteride. The results show that twice-daily dosing of the new treatment is slightly more effective than once-daily, but concerns about cost, side effects, and the accuracy of reported results remain.
