Treatment of Male Rats with Finasteride, an Inhibitor of 5alpha-Reductase Enzyme, Induces Long-Lasting Effects on Depressive-Like Behavior, Hippocampal Neurogenesis, Neuroinflammation, and Gut Microbiota Composition

research Treatment of Male Rats with Finasteride, an Inhibitor of 5alpha-Reductase Enzyme, Induces Long-Lasting Effects on Depressive-Like Behavior, Hippocampal Neurogenesis, Neuroinflammation, and Gut Microbiota Composition

37 citations , September 2018 in “Psychoneuroendocrinology”

This study found that finasteride treatment in male rats led to enduring effects on depressive-like behavior, hippocampal neurogenesis and neuroinflammation, and gut microbiota composition after withdrawal.

research The Risk of Dementia with the Use of 5 Alpha Reductase Inhibitors

18 citations , June 2017 in “Journal of the neurological sciences”

In this study, the use of 5 alpha reductase inhibitors was associated with an increased risk of dementia during the first two years of treatment, but the risk was not significant with longer exposure.

research Investigation of the Plausibility of 5-Alpha-Reductase Inhibitor Syndrome

33 citations , January 2016 in “Skin appendage disorders”

This review examines medical literature on postfinasteride syndrome and reports no new results; the authors call for more controlled studies on permanent sexual dysfunction and mood changes linked to 5-alpha-reductase inhibitors.

research Effects of Subchronic Finasteride Treatment and Withdrawal on Neuroactive Steroid Levels and Their Receptors in the Male Rat Brain

33 citations , December 2015 in “Neuroendocrinology”

This study found that subchronic finasteride treatment in male rats altered neuroactive steroid levels and steroid receptor expression in the brain, with some changes persisting after drug withdrawal.

research Appropriateness of Oral Drugs for Long-Term Treatment of Lower Urinary Tract Symptoms in Older Persons: Results of a Systematic Literature Review and International Consensus Validation Process (LUTS-FORTA 2014)

111 citations , June 2015 in “Age and Ageing”

This study classified dutasteride, fesoterodine, and finasteride as beneficial for older or frail elderly patients, while suggesting caution or avoidance of α-blockers and antimuscarinics in this group.

Patients Treated for Male Pattern Hair Loss with Finasteride Show Altered Levels of Neuroactive Steroids in Cerebrospinal Fluid and Plasma After Discontinuation

research Patients Treated for Male Pattern Hair Loss with Finasteride Show Altered Levels of Neuroactive Steroids in Cerebrospinal Fluid and Plasma After Discontinuation

61 citations , April 2014 in “The Journal of Steroid Biochemistry and Molecular Biology”

This study reports that men with androgenic alopecia experience altered neuroactive steroid levels associated with persistent depression symptoms even after stopping finasteride treatment.

research Side Effects of 5-Alpha Reductase Inhibitors: A Comprehensive Review

35 citations , April 2013 in “Sexual medicine reviews”

This review found that 5α-reductase inhibitors are associated with slightly increased rates of sexual dysfunction, gynecomastia, and mood disorders, but the true significance and persistence of these effects remain unclear.
