Glossary Androgen Receptor Antagonists

block male hormones like testosterone from affecting tissues

Androgen Receptor Antagonists, also known as antiandrogens, are medications that block the action of androgens, which are male sex hormones like testosterone. These drugs work by binding to androgen receptors, preventing androgens from exerting their effects on tissues, and are commonly used in the treatment of conditions like prostate cancer, androgenic alopecia (male-pattern baldness), and certain types of acne.

community Is there any role for topical DHT antagonists, or does a 5-AR inhibitor remove the need for them as therapy

2 upvotes 1 year ago

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.

community Anyone know by what percentage Pyrilutamide or Ru decrease your androgens?

in Chat 1 upvotes 1 year ago

Pyrilutamide and RU58841 are androgen receptor antagonists that block receptors without significantly reducing testosterone or DHT levels. Any indirect effect on androgen levels is likely negligible.

community How is the GT20029 different to pyrilutamide as an androgenic antagonist

1 year ago

GT20029 and pyrilutamide are both androgen antagonists but work differently; GT20029 degrades the androgen receptor, while pyrilutamide blocks DHT from binding. GT20029 is expected to have similar efficacy to CosmeRNA.

community Is there a topical androgen receptor blocker so we don't have to fuck with the enzyme and destroy our allopregnanolone, but go and hit the end target straight?

in Treatment 44 upvotes 2 years ago

The conversation discusses topical androgen receptor blockers for hair loss, mentioning Clascoterone, Pyrilutamide, GT20029, and RU58841. Ketoconazole's effectiveness and application methods are also debated.

community Pyrilutamide for Hair Loss!? (Ft. Steve Cook)

in Satire 4 upvotes 4 months ago

Pyrilutamide is discussed as a potential hair loss treatment, acting as an androgen receptor antagonist. The conversation questions if it can maintain hair long-term without using finasteride.

learn Clascoterone

a novel topical treatment that inhibits DHT on androgen receptors

learn Pyrilutamide

highly targeted anti-androgen that might have minimal systemic effects

learn Spironolactone

powerful topical and oral anti-androgen used mostly by women

learn Bicalutamide

a nonsteroidal anti-androgen, most commonly used orally for women

Can bicalutamide stop DHT from shrinking your hair follicles? Bicalutamide blocks androgens at the receptor rather than lowering DHT, and some dermatologists prescribe it off-label for women with pattern hair loss. The published evidence is retrospective case series and one small pilot study, with no randomized trial; it is a prescription drug that requires liver monitoring and is contraindicated in pregnancy.

learn Overview

learn GT20029

What is GT20029 and how does it work as a topical anti-androgen for hair loss? GT20029 is a topical anti-androgen that degrades androgen receptors to combat hair loss.

learn Fluridil

How is Fluridil different from other DHT blockers like finasteride? Fluridil is a topical androgen-receptor blocker applied to the scalp, while finasteride is an oral 5-alpha-reductase inhibitor that lowers DHT throughout the body. Finasteride is FDA-approved and far better studied; Fluridil rests on one 43-man trial and is not licensed as a hair-loss medicine, so its long-term safety and effect size are unknown.

learn KX-826

Kintor Pharmaceutical: KX-826, a New Name in Hair Loss Research KX-826 (pyrilutamide) is an experimental topical androgen receptor blocker from Kintor Pharmaceutical. It is not approved as a medicine anywhere; the company reports that its China Phase III trial met its primary endpoint at 24 weeks, but the trial data has been released through corporate announcements rather than peer-reviewed journals and long-term safety is unknown.

learn Exosomes

What does Fluridil do on the scalp, and how does it block the DHT hormone? Fluridil blocks DHT by binding to androgen receptors in hair follicles, preventing hair loss.
