    GlossaryPhosphodiesterase Inhibitors

    block enzymes that break down cyclic nucleotides

    Phosphodiesterase Inhibitors (PDE Inhibitors or PDEIs) are a class of drugs that block the action of phosphodiesterase enzymes, which are responsible for breaking down cyclic nucleotides like cAMP and cGMP. By inhibiting these enzymes, PDE inhibitors can increase the levels of these cyclic nucleotides, leading to various therapeutic effects such as vasodilation, anti-inflammatory actions, and improved cardiac function. These drugs are used to treat conditions like erectile dysfunction, pulmonary hypertension, and certain types of heart failure.

      community Does caffeine inhibit 5-α-reductase?

      in Treatment  4 upvotes 6 years ago
      Caffeine may promote hair growth and potentially inhibit 5-α-reductase activity in hair follicles, but its effectiveness and systemic impact remain unclear. Users discuss using topical caffeine solutions, with some experiencing no side effects compared to finasteride.

      community Could creatine trigger faster hairloss?

      in Research/Science  29 upvotes 1 year ago
      Creatine is reported by many to increase hair loss, though no scientific evidence supports this. Some use finasteride and minoxidil to manage hair loss, while others avoid creatine due to personal experiences.

      community Does anyone know of the actual effectiveness of the DP2 inhibitors?

      in Question  4 upvotes 8 years ago
      Setipiprant and Fevipiprant are questioned for their effectiveness in hair maintenance, with skepticism due to lack of convincing results beyond vellus hair growth. The user is satisfied with Minoxidil and Finasteride but is curious about the potential of DP2 inhibitors.
      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 1 year ago
      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.

      community VDPHL01 phase-2/3 results comparison

      in Research/Science  128 upvotes 2 weeks ago
      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.

      community Similar 5ar inhibitors to fin?

      in Finasteride/Dutasteride 4 years ago
      Natural vitamins like pumpkin seed oil, saw palmetto, and ecklonia cava are discussed for their potential to lower DHT levels. They may work similarly to finasteride but are significantly weaker.

      community P5P supplementation for fin sides.

      P5P supplementation helped reverse finasteride side effects, particularly by lowering prolactin levels and restoring sensitivity. The user experienced significant improvement within a day and full recovery in a few days.

      community DLQ01: A Better "Minoxidil" PGF2a synthetic analogue.

      in Research/Science  3 upvotes 1 year ago
      DLQ01, a prostaglandin F2α analog, shows promise for hair growth by directly stimulating PGE2/PGF receptors without needing conversion, and can be combined with minoxidil and retinoids like tretinoin for enhanced effectiveness. Minoxidil's efficacy may be reduced by COX-1 inhibitors, but using prostaglandin analogs like Latanoprost or Bimatoprost can help maintain its effectiveness.

      community What is fluridil binding affinity?

      in Treatment  4 upvotes 4 years ago
      Fluridil is hard to obtain and only available in Slovakia and Czechia, with no systemic side effects but possibly limited effectiveness compared to finasteride. The original poster is using finasteride and minoxidil without success and is considering trying fluridil despite its cost.

      community How would you react if PP405 isn't successful in phase 3 trials?

      in Chat  23 upvotes 5 months ago
      People are discussing their reactions if PP405 fails in phase 3 trials, with some expressing skepticism and others holding onto hope for future treatments like GT20029 and Breezula.

      community EU Shouldn't Ban Fin & Dut: PFS is NOT REAL.

      in Research/Science  11 upvotes 1 year ago
      Finasteride and Dutasteride do not cause depression or "Post Finasteride Syndrome," with concerns often linked to the nocebo effect and preexisting mental health issues. The EU is unlikely to ban these drugs, but access may become more restricted due to ongoing debates.

      community PYRILUTAMIDE PHASE 3 RESULTS : No statistical significance

      in Research/Science  127 upvotes 2 years ago
      The phase 3 trial results for Pyrilutamide showed no significant difference from the control treatment in increasing hair count, leading to the company halting its development. Users discussed their disappointment and skepticism about hair loss treatments, with some mentioning other treatments like Minoxidil, Finasteride, and RU58841.

      community I'm very skeptical about pyrilutamide

      in Product  2 upvotes 2 months ago
