    GlossaryPharmacokinetic Studies

    investigate how drugs move through and are processed by the body

    Pharmacokinetic Studies, often abbreviated as PK Studies, investigate how a drug is absorbed, distributed, metabolized, and excreted in the body. These studies help determine the appropriate dosage and frequency to ensure the drug's efficacy and safety.

      Hair loss treatments discussed include Dutasteride with Ketoconazole, tissue engineering strategies, and androgenetic alopecia therapies. Massage doubles follicular retention, improving treatment effectiveness.

      community Are we underestimating systemic absorption with homemade/generic Topical Fin? (HPCH vs. PG/Ethanol formulations)

      in Research/Science  5 upvotes 2 months ago
      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.
      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.
