    study of how drugs move through the body

    Pharmacokinetics (PK) is the study of how a drug moves through the body over time. It involves four main processes: absorption (how the drug enters the bloodstream), distribution (how the drug spreads through the body's tissues), metabolism (how the body breaks down the drug), and excretion (how the drug is eliminated from the body). Understanding PK helps in determining the appropriate dosage and frequency of medication to ensure its effectiveness and safety.

      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 2 months 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.
