    GlossaryDrug Absorption

    process by which a drug enters the bloodstream from administration

    Drug absorption refers to the process by which a drug enters the bloodstream from its site of administration. This can occur through various routes such as oral, intravenous, or topical application. The efficiency and rate of absorption can be influenced by factors like the drug's formulation, the presence of food in the stomach, and the health of the gastrointestinal tract. Understanding drug absorption is crucial for determining the correct dosage and ensuring the drug's effectiveness.

      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 3 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.

      community What makes breezula different than formula 82f?

      in Question  7 upvotes 4 years ago
      Breezula (clascoterone) and Formula 82F (topical finasteride) are treatments for hair loss that block DHT differently; Breezula competes with DHT at the hormone receptor site without systemic effects, while 82F inhibits the enzyme that converts testosterone to DHT. Breezula may work for those who don't respond to finasteride and vice versa.
