Isolation stress in rats reduces brain enzyme levels, affecting dopamine function.

This meta-analysis concluded that 5α-reductase inhibitors may increase the risk of mild depression, particularly with dutasteride, in patients treated for benign prostatic hyperplasia and androgenic alopecia.

This article reviews ongoing concerns about the safety of 5α-reductase inhibitors like finasteride, highlighting the lack of long-term data on persistent depression and sexual side effects after drug discontinuation; no new clinical results are reported.

In this study involving a mouse model, researchers reported that intranasal delivery of protein-based CRISPR/dCas9 nanoparticles targeting the gene *Sirt1* reduced cerebral edema and increased survival following ischemic stroke, with no significant toxicity observed.

In this case study, a 29-year-old male experienced chronic pelvic pain and erectile dysfunction after finasteride use, with no effective relief from pharmacological and procedural interventions, prompting a shift towards pain education and behavioral strategies due to a possible nociplastic pain mechanism.

This policy brief reports that post-drug syndromes like Post-Finasteride Syndrome are largely overlooked in current pharmacovigilance systems, which prioritize acute drug reactions, resulting in inadequate recognition and management of persistent medication-induced conditions.

This study found that 5-alpha-reductase inhibitor monotherapy for symptomatic benign prostatic hyperplasia showed some clinical benefit over placebo but was linked to a higher incidence of sexual side effects.

The study found that ondansetron decreased alcohol consumption only in adult rats that experienced altered neuroactive steroid levels from early post-natal finasteride exposure, suggesting increased 5HT3 receptor sensitivity in these rats.

This review discusses various herbal and pharmaceutical products, including their purported uses and possible interactions, but reports no new research findings.

This study developed a Neusilin® US2-based solid self-nanoemulsifying drug delivery system for finasteride that showed improved stability and drug delivery, with complete dissolution comparable to standard Propecia® tablets.

This study suggests that using opioids along with 5αRI may reduce opioid use disorder risk in humans, supporting similar findings from animal studies.

This study observed that androgenic alopecia patients taking finasteride had altered neuroactive steroid levels and persistent depression symptoms even after stopping the treatment.

This study reported that cognitive biopsy diagnosed prostate cancer in 44% of patients with at least one previous negative biopsy, with higher detection rates in lesions classified as PI-RADS 4 and 5.

This study found that chronic treatment with EE/LNG in female rats decreased brain concentrations of allopregnanolone, leading to reduced social and sexual behaviors; progesterone administration reversed these effects, except when finasteride was used to block the increase.

Using hair loss drugs finasteride and dutasteride may cause sexual side effects.

This review discusses sexual dysfunction as a potential side effect of drugs for Benign Prostatic Hyperplasia and Lower Urinary Tract Symptoms and reports no new clinical results; it emphasizes the need for methodologically robust studies.

This study found that neuroactive steroids like DHEA and pregnenolone influence cocaine-induced appetence in mice through their interaction with the ς₁ receptor, suggesting a role in individual vulnerability to addiction.

This policy brief found that post-drug syndromes are under-recognized in current pharmacovigilance systems, leading to inadequate risk assessments and prolonged patient harm from persistent drug-induced conditions.

This study found that NIMP-R14-conjugated nanoparticles, loaded with roflumilast, effectively targeted neutrophils to reduce inflammation and improve symptoms in a mouse model of psoriasiform dermatitis, suggesting potential for targeted therapy in autoimmune skin diseases.

This study found that a complex extract of Polygonatum sibiricum and Nelumbinis semen improved menopause symptoms in an ovariectomized rat model by enhancing blood lipid metabolism and reducing osteoporosis, without increasing risks of side effects like endometriosis, unlike conventional hormone-replacement therapy.

This review discusses the impact of 5α-reductase inhibitors on sexual function and presents results from a meta-analysis of randomized controlled trials, without reporting new clinical findings.

In this study, finasteride was found to significantly reduce DHT levels and affect spermatogenic markers in rats, while DA-9401 co-treatment indicated potential ameliorative effects.

This study identified significant changes in the expression of nine proteins in the nucleus accumbens of rats treated with finasteride, suggesting potential novel targets for its neuropsychiatric effects.
