research New Drugs: Dutasteride
Dutasteride is approved to help manage prostate enlargement.
research Synthesis, Characterization and Evaluation of 5α, 6β-Dihalo Androsterone Derivatives as 5α-Reductase Inhibitors
Compound 7b is a promising candidate for treating benign prostatic hyperplasia and prostate cancer.
research Determination Method for Steroid 5α-Reductase Activity Using Liquid Chromatography/Atmospheric Pressure Chemical Ionization–Mass Spectrometry
A new method was developed to measure and assess the activity and inhibition of the enzyme steroid 5α-reductase.
research Prostatakarzinom
5α-reductase inhibitors lower overall prostate cancer risk but not high-grade cancer risk; longer-term screening and new treatments show promise.
research Clinical application of 5α-reductase inhibitors
5α-reductase inhibitors, like finasteride and dutasteride, effectively treat BPH, male baldness, and hirsutism, with potential for acne and prostate cancer prevention.
research Re: Association of Treatment with 5α-Reductase Inhibitors with Time to Diagnosis and Mortality in Prostate Cancer
Treatment with 5α-reductase inhibitors is linked to a delay in prostate cancer diagnosis and may affect survival rates.
research Depression risk of 5-alpha reductase inhibitors: A systematic review and meta-analysis with a focus on comparator groups
5-alpha reductase inhibitors may increase depression risk by 31%, but results vary based on comparison groups.
research Drug–Drug Coamorphous System of Tadalafil and Finasteride for Enhanced Pharmaceutical Performance
Combining tadalafil and finasteride improves their solubility and effectiveness.
research Serenoa repens induced erectile dysfunction: Underdiagnosis and phytovigilance
Saw palmetto may cause erectile dysfunction and needs better safety monitoring.
research Finasteride interferes with prostaglandin-induced CatSper signalling in human sperm
Finasteride may affect male fertility by interfering with specific sperm signaling.
research 5α-Reductase Inhibitors (5ARIs) and Male Reproduction
5α-Reductase inhibitors can negatively affect male sexual function and, in some cases, significantly reduce sperm count, but these effects may be reversible.
research Finasteride: The First 5α-Reductase Inhibitor
Finasteride treats enlarged prostate and baldness, but may cause limited urinary improvement and sex-related side effects.
research Testosterone, cytochrome P450, and cardiac hypertrophy
Heart-specific steroid metabolism is crucial in cardiac hypertrophy.
research Chemical Mechanism of the Covalent Modification of 5.alpha.-Reductases by Finasteride as Probed by Secondary Tritium Isotope Effects
Finasteride modifies 5-alpha-reductases through a two-step process, affecting inhibitor potency and possibly causing side effects.
research Finasteride Inhibits Human Prostate Cancer Cell Invasion through MMP2 and MMP9 Downregulation
Finasteride may reduce prostate cancer spread by lowering certain enzyme levels.
research Effects of prasugrel versus clopidogrel on coronary microvascular function in patients undergoing elective percutaneous coronary intervention: A randomized double-blind study
Prasugrel is better than clopidogrel at preventing heart damage and improving blood flow in small heart vessels during heart artery procedures.
research Effect of MK-386, a novel inhibitor of type 1 5 alpha-reductase, alone and in combination with finasteride, on serum dihydrotestosterone concentrations in men
research Abietic Acid from Resina Pini of Pinus Species as a Testosterone 5.ALPHA.-Reductase Inhibitor
Abietic acid from pine resin can effectively inhibit testosterone 5α-reductase.
research No increased risk of CV events with dutasteride vs finasteride
Dutasteride and finasteride have equal safety for treating BPH without increased heart risk.
research Comparison of combination therapy with tamsulosin and dutasteride or finasteride in patients with benign prostatic hyperplasia: a randomized clinical trial
Dutasteride is slightly better than finasteride for treating BPH but has fewer sexual side effects.
research Synthesis of mimics of steroid A ring as potential enzyme inhibitors
Mimicking the steroid A-ring may help create effective enzyme inhibitors for prostate disease treatment.
research A model for the turnover of dihydrotestosterone in the presence of the irreversible 5α-reductase inhibitors GI198745 and finasteride
Both drugs lower DHT levels, with GI198745 being more effective.
research COMPARISON OF FINASTERIDE AND ALPHA‐BLOCKERS AS INDEPENDENT RISK FACTORS FOR ERECTILE DYSFUNCTION
Age and other health issues affect erectile dysfunction more than finasteride or alpha-blockers.
research Development of a new gas chromatography–mass spectrometry (GC–MS) methodology for the evaluation of 5α-reductase activity
A new method was developed to accurately measure enzyme activity related to prostate health.
research Dutasteride/finasteride
research Generation of comparative pharmacophoric model for steroidal 5α-reductase I and II inhibitors: A 3D-QSAR study on 6-azasteroids
The study created a model to help design new inhibitors for steroidal 5α-reductase enzymes.
research The 5α-reductase inhibitor Dutasteride but not Finasteride protects dopamine neurons in the MPTP mouse model of Parkinson’s disease
Dutasteride protects dopamine neurons in Parkinson's mice, but Finasteride doesn't.
research The expression of inducible nitric oxide synthase (iNOS) in the testis and epididymis of rats with a dihydrotestosterone (DHT) deficiency
DHT deficiency increases iNOS expression in rat testis and epididymis.
