Despite the impressive increase of knowledge on acne etiology accumulated during the last 20 years, few efforts have been overtaken to introduce new therapeutic regiments targeting the ideal treatment of acne. The increasing emergence of microbial resistance associated with antibiotics, teratogenicity, particularly associated with systemic isotretinoin, and the need for an adverse drug profile, which can be tolerated by the patient, make the need of new pathogenesis relevant anti-acne agents an emerging issue...

RATIONALE: Social isolation of rats immediately after weaning is thought to represent an animal model of anxiety-like disorders. Socially isolated virgin females showed a significant decrease in allopregnanolone levels, associated with increased anxiety-related behavior compared with group-housed rats. OBJECTIVES: The present study investigates whether post-weaning social isolation affects maternal behavior and assesses neuroactive steroid levels in adult female rats during pregnancy and postpartum...

Tourette syndrome (TS) is a neuropsychiatric disorder characterized by multiple tics and sensorimotor abnormalities, the severity of which is typically increased by stress. The neurobiological underpinnings of this exacerbation, however, remain elusive. We recently reported that spatial confinement (SC), a moderate environmental stressor, increases tic-like responses and elicits TS-like sensorimotor gating deficits in the D1CT-7 mouse, one of the best-validated models of TS. Here, we hypothesized that these adverse effects may be mediated by neurosteroids, given their well-documented role in stress-response orchestration...

Androgenetic alopecia (AGA) is a common form of scalp hair loss that affects up to 50% of males between 18-40 years old. Several molecules are commonly used for the treatment of AGA, acting on different steps of its pathogenesis (Minoxidil, Finasteride, Serenoa repens) and show some side effects. In literature, on the basis of hypertrichosis observed in patients treated with analogues of prostaglandin PGF2α, was supposed that prostaglandins would have an important role in the hair growth: PGE and PGF2α play a positive role, while PGD2 a negative one...

OBJECTIVE: The objective of this study was to assess the efficacy of tamsulosin and finasteride monotherapies, and their combination in men with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: This is a prospective single-blind randomized study of ninety men with BPH who were managed using drugs. The International Prostate Symptom Score (IPSS), peak urinary flow rate, and prostate volume were measured as parameters for assessment at the beginning, 3 months, and 6 months of the study...

RESULTS: Compared with the model group(MG), Motherwort total alkaloid high, medium dose group(HD, MD) could significantly reduced the pathological changes of the prostate (P < 0.01); Finasteride(FG) and Motherwort total alkaloid low dose group(LD) could significantly reduce the pathological changes of the prostate (P < 0...

Neonatal neuroactive steroids levels are crucial for brain development. Alterations of neonatal neuroactive steroids levels induce anxiolytic-like effects and improve exploration in novel environments in adulthood. These behavioural traits, i.e. sensation/novelty seeking, anxiety or impulsivity, are associated with vulnerability to drug use and abuse. Adolescence is also recognized as a particularly critical developmental phase to contribute to vulnerable phenotype. However, the influence of neuroactive steroids during development in the vulnerability to drug addiction has been poorly studied...

Benign prostatic hyperplasia (BPH) is the most common cause of lower urinary tract symptoms (LUTS) in older men. In this regard, recent studies have attempted to define the relationships between prostatic fibrosis, LUTS, and increased expression of transforming growth factor β1 (TGF β1) in BHP. Therapeutic approaches for BPH such as 5-α-reductase inhibitors and alpha-adrenergic blocking agents increase TGF β1 expression in the prostatic tissue. Here, we investigated the effects of the 5-α-reductase inhibitor-finasteride-on rat ventral prostate tissue, especially with regard to the tissue distribution and gene expression of fibrillar collagens...

BACKGROUND: Finasteride and dutasteride are competitive inhibitors of 5α-reductase enzymes and are commonly used to treat symptomatic benign prostatic hyperplasia (BPH). OBJECTIVE: To compare the efficacy and safety of finasteride and dutasteride in terms of clinically important outcomes. DATA SOURCES: A literature search was performed using the search terms "prostatic hyperplasia", "prostatic hypertrophy", "dutasteride", "finasteride", "quality of life", "adverse drug reaction", and "mortality"...

Despite their efficacy in the treatment of benign prostatic hyperplasia, the popularity of inhibitors of 5α-reductase (5ARIs) is limited by their association with adverse sexual side effects. The aim of this study was to review and meta-analyze currently available randomized clinical trials evaluating the rate of sexual side effects in men treated with 5ARIs. An extensive Medline Embase and Cochrane search was performed including the following words: 'finasteride', 'dutasteride', 'benign prostatic hyperplasia'...

OBJECTIVE: We determined the role of the neurosteroid-sensitive δ subunit-containing γ-aminobutyric acid A receptors (δ-GABARs) in epileptogenesis. METHODS: Status epilepticus (SE) was induced via lithium pilocarpine in adult rats, and seizures were assessed by continuous video-electroencephalography (EEG) monitoring. Finasteride was administered to inhibit neurosteroid synthesis. The total and surface protein expression of hippocampal δ, α4, and γ2 GABAR subunits was studied using biotinylation assays and Western blotting...

Androgenetic alopecia (AGA) is characterized by a progressive and patterned transformation of thick, pigmented terminal scalp hairs into short, hypo-pigmented vellus-like hairs. The use of Minoxidil and Finasteride to treat AGA are often associated with complications in safety and efficacy. However, herbal remedies are deemed to have lesser side effects in many societies. This study aims to identify potential hair growth properties of individual compounds from a Chinese proprietary medicine known as Yangxue Shengfa capsule (YSC), used in China for many years for improving AGA...

This study aimed to evaluate the inhibitory effects and explore mechanisms of chlorogenic acid against testosterone-induced benign prostatic hyperplasia (BPH) in mice. Benign prostatic hyperplasia model was induced in experimental groups by daily subcutaneous injections of testosterone propionate (7.5mg/kg/d) consecutively for 14 d. A total of 60 mice were randomly divided into six groups: (Group 1) normal control group, (Group 2) benign prostatic hyperplasia model control group, (Group 3) benign prostatic hyperplasia mice treated with finasteride at a dose of 1mg/kg, (Group 4) benign prostatic hyperplasia mice treated with chlorogenic acid at dose levels of 0...

Recent reports show that, in patients treated with finasteride for male pattern hair loss, persistent side effects including sexual side effects, depression, anxiety and cognitive complaints may occur. We here explored the psychiatric and andrological features of patients affected by post-finasteride syndrome (PFS) and verified whether the cerebrospinal fluid (CSF) and plasma levels of neuroactive steroids (i.e., important regulators of nervous function) are modified. We found that eight out of sixteen PFS male patients considered suffered from a DSM-IV major depressive disorder (MDD)...

The neurosteroid allopregnanolone (3α, 5α-tetra-hydroprogesterone: ALLO) elicits anxiolytic, anticonvulsant, and hypnotic anesthetic effects in vivo similar to those induced by other positive allosteric modulators of the GABAA receptor. Endogenous ALLO has been shown to be rapidly elevated in the brain by acute stress paradigms, such as immobilization, in animal models. The present study was designed to ascertain the role of neurosteroid biosynthesis in the anxiety-like behavior induced by immobilization stress...

BACKGROUND: Androgenetic alopecia, or male pattern hair loss, is a hair loss disorder mediated by dihydrotestosterone, the potent form of testosterone. Currently, minoxidil and finasteride are Food and Drug Administration (FDA)-approved, and HairMax LaserComb, which is FDA-cleared, are the only treatments recognized by the FDA as treatments of androgenetic alopecia. OBJECTIVE: This systematic review and meta-analysis assesses the efficacy of nonsurgical treatments of androgenetic alopecia in comparison to placebo for improving hair density, thickness, growth (defined by an increased anagen:telogen ratio), or subjective global assessments done by patients and investigators...
