research Optimizing clinical monitoring and management guidelines for capivasertib in HR-positive/HER2-negative advanced breast cancer: expert opinion
In the phase 3 CAPItello-291 trial, capivasertib combined with fulvestrant significantly increased progression-free survival in patients with advanced breast cancer with specific genetic alterations, but the authors highlight that managing side effects like diarrhea, rash, and hyperglycemia is crucial for optimizing treatment adherence and outcomes.
research TACRINE
This article lists the clinically important interactions and skin reactions of several drugs and substances, including THA, FK506, tamoxifen, tamsulosin, tartrazine, tea tree oil, temazepam, and temozolomide, but provides no new clinical results.

This study found that 5-alpha reductase inhibitors had the highest association with erectile dysfunction reports among medications analyzed in the FDA's national pharmacovigilance database.
research Drug News
Actemra is approved for a specific artery condition, HIV treatment adherence has improved, women may pay more for a hair loss product, and incorrect dosing of blood thinners can be risky.
research Identification of neprilysin as a potential target of arteannuin using computational drug repositioning
This study identified neprilysin as a potential target of the pharmacological agent arteannuin, which may guide future research into its clinical applications, although experimental verification is needed.
research Inhibition of 5α-reductase in the nucleus accumbens counters sensorimotor gating deficits induced by dopaminergic activation
Finasteride may help improve certain brain function issues linked to dopamine.
research A Randomized Trial of Oral DHEA Treatment for Sexual Function, Well-Being, and Menopausal Symptoms in Postmenopausal Women with Low Libido
In this study, 50 mg/day of DHEA supplementation in postmenopausal women did not significantly improve sexual function compared to a placebo over 26 weeks.
research Citalopram–induced delusions in an older adult
This case report describes a 64-year-old woman who developed delusions after starting citalopram, highlighting citalopram-induced psychosis in older adults as a potential but rare side effect.
research Midazolam Inhibits Hippocampal Long-Term Potentiation and Learning through Dual Central and Peripheral Benzodiazepine Receptor Activation and Neurosteroidogenesis
This study found that midazolam, unlike clonazepam, increased neurosteroid levels and affected synaptic inhibition and plasticity in rat hippocampal neurons, suggesting unique actions via dual receptor activation.
research Experimental Evaluation of 3-meta-Pyridine-1,2,4-Oxadiazole Derivative of Deoxycholic Acid as a Prototype of 5-α-Reductase Inhibitors in In Silico and In Vivo Models
In an animal study, researchers observed that a newly synthesized deoxycholic acid derivative showed similar prostate protection effects to finasteride in Wistar rats while being less toxic.
research Ruolo dei neurosteroidi nella modulazione dopaminergica
In this study, finasteride reduced the severity of dopaminergic behavior manifestations in rats without causing extrapyramidal side effects, unlike other antidopaminergic agents.
research Dutasteride reduces alcohol’s sedative effects in men in a human laboratory setting and reduces drinking in the natural environment
This study found that dutasteride pretreatment reduced certain sedative effects of alcohol and may decrease drinking behavior in adult men, likely by impacting neuroactive steroid levels.
research Gynécomastie et finastéride (Propecia®) : 4 nouveaux cas
This review summarizes the adverse effects associated with 5α‐reductase inhibitors, noting slightly increased rates of decreased libido, erectile and ejaculatory dysfunction, gynecomastia, depression, and anxiety, with further studies needed to explore symptom prevalence and persistence.
research 75810 Long-term efficacy, complete scalp hair regrowth, and normal body hair and nails in patients with alopecia areata (AA) receiving ritlecitinib 50 mg once daily up to 3 years in the ALLEGRO clinical trial program
research The involvement of the neurosteroid allopregnanolone in the antihyperalgesic effect of paroxetine in a rat model of neuropathic pain
In this study, paroxetine's antihyperalgesic effect in a rat model of neuropathic pain was shown to be mediated by increased levels of the neurosteroid allopregnanolone in the spine.
research Depression risk of 5-alpha reductase inhibitors: impact of active-comparator versus non-drug user control groups on risk measurement
This meta-analysis reports that 5-alpha-reductase inhibitors are associated with a 31% increased risk of depression, with varying outcomes depending on the comparator group, highlighting significant heterogeneity across studies.

research Effect of flutamide and two novel synthetic steroids on GABA, glutamine and some oxidative stress markers in rat brain and prostate
This study concluded that 16β-methyl-17α-benzoyloxypregnen-4-en-3,20-dione may be a promising treatment for androgen-dependent diseases and epilepsy due to its antioxidant effects and impact on GABAergic and serotonergic metabolism in rats.
research Adverse Side Effects of 5α‐Reductase Inhibitors Therapy: Persistent Diminished Libido and Erectile Dysfunction and Depression in a Subset of Patients
This review discusses persistent adverse effects of 5α‐reductase inhibitors, like diminished libido and erectile dysfunction, in some patients and highlights the need for patient discussions before therapy, especially for androgenetic alopecia.
