Glossary Nonsteroidal Antiandrogens

medications that block male hormones without activating their receptors

Nonsteroidal Antiandrogens (NSAA) are medications that block the action of androgens (male hormones like testosterone) by binding to androgen receptors without activating them. They are commonly used in the treatment of conditions like prostate cancer and androgenic alopecia (hair loss) by preventing androgens from stimulating the growth of cancer cells or hair follicles.

community Has anyone find a way to stop/limit ru58841 to go systematic ?

in Finasteride/Dutasteride 4 upvotes 1 year ago

RU58841 is a strong non-steroidal antiandrogen for hair loss but may cause cardiovascular issues in some users. Alternatives like Pyrilutamide and Breezula are suggested due to better safety profiles and lower systemic risks.

community Severe dry eye: finasteride vs dutasteride

8 upvotes 5 years ago

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.

community Which 2026 hair‑loss treatments have the strongest evidence so far? (minoxidil/finasteride vs. clascoterone, PP405, Re:You’s NV‑623/624, AMP‑303, RU58841)

44 upvotes 3 months ago

Minoxidil and finasteride are the only FDA-approved treatments for androgenetic alopecia, while newer treatments like clascoterone, PP405, NV-623/624, AMP-303, and RU58841 are still experimental with varying levels of evidence. Clascoterone shows the most promise due to strong human data, while AMP-303 has notable early human trial results; RU58841 lacks human data and remains experimental.

community Study: There is 70x Higher Unconjugated DHT in Feces Compared To Blood Levels in Young Adults - Gut Microbiota Manages DHT Recycling and Metabolism

in Research/Science 194 upvotes 1 year ago

Gut microbiota significantly influences androgen metabolism, impacting hair loss treatments like finasteride. Probiotics, dietary changes, and fecal microbiota transplants may help manage DHT levels and improve hair health.

community Is this broscience? From More Plates, More Dates

in Research/Science 21 upvotes 2 years ago

The conversation discusses whether finasteride's reduction of DHT and increase in scalp testosterone contribute to hair follicle miniaturization. Some participants argue testosterone does not cause miniaturization, while others suggest that even with reduced DHT, other androgens like testosterone may still contribute to hair loss.

Experimental topical anti-androgen, also known as KX-826

Is pyrilutamide a safer alternative to oral antiandrogens like finasteride? Pyrilutamide (KX-826) is an unapproved, investigational topical antiandrogen whose safety data come from short-term sponsor announcements, not peer-reviewed studies. No study has compared it with finasteride, so there is no evidence that it is safer.
