    TLDR Some medications for bladder problems can cause memory issues or mood changes, and doctors should monitor these side effects.
    The document reviewed the cognitive and mood side effects of medications for lower urinary tract symptoms, finding that muscarinic receptor antagonists, especially oral oxybutynin, pose a high risk for cognitive impairment. 5α-reductase inhibitors, used also for androgenetic alopecia, were associated with depressive symptoms and possibly dementia, with these effects potentially persisting after treatment cessation. The evidence for α₁-adrenoceptor antagonists, like tamsulosin, affecting cognition was controversial and inconclusive. The document recommended careful monitoring of mental status by physicians when prescribing these medications and considering alternative treatments for at-risk patients. It also highlighted methodological issues in existing studies and the need for further research, while noting regulatory updates to prescribing information regarding the risk of depressive symptoms with 5α-reductase inhibitors. The document did not specify the number of participants in the studies reviewed.

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 7 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.

      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.

      in Research/Science  639 upvotes 3 weeks ago
      Dutasteride may cause chronic infertility by reducing semen volume and motility, with concerns about irreversible prostate fibrosis. Users consider switching to finasteride or using treatments like minoxidil and microneedling, weighing hair preservation against fertility.
