This review outlines drug repurposing as an efficient, low-cost strategy to identify new uses for existing drugs, highlighting various computational and experimental approaches as well as publicly available databases to aid in personalized pharmacotherapy.

In this study, pregnenolone was found to dose-dependently reduce L-DOPA-induced dyskinesias in a rat model of Parkinson's disease, suggesting its potential as a therapeutic target for these dyskinesias.

Finasteride reduces gambling symptoms in Parkinson's patients.

This study suggests that the 5α-reductase inhibitor finasteride modulates sensorimotor gating in rats by affecting D1 and D3 receptors, but not D2 receptors, with varying effects based on genetic strain.

Finasteride reduces certain behaviors caused by D1-like receptor agonists but not by D2-like receptor agonists in mice.

Finasteride may help improve certain brain function issues linked to dopamine.

In this study, finasteride reduced the severity of dopaminergic behavior manifestations in rats without causing extrapyramidal side effects, unlike other antidopaminergic agents.

This study found that in animal models of Tourette syndrome, stress-induced tic-like behaviors and sensorimotor gating deficits were reduced by finasteride, suggesting a role for neurosteroids like allopregnanolone.

This study found that in rodent models, the ability of D1 dopamine receptor activation to impair sensory gating is facilitated by 5α-reductase type 1, which produces allopregnanolone.

This study found that both finasteride and dutasteride significantly reduced L-DOPA-induced dyskinesia in a rat model of Parkinson's disease, with dutasteride showing greater effectiveness at lower doses.

This study found that in sleep-deprived rats, increased 5α-reductase expression and activity in the prefrontal cortex contributed to psychosis- and mania-like symptoms, which finasteride ameliorated in a dose-dependent manner.

In this review, the researchers reported that 5α-reductase inhibitors demonstrated neuroprotective effects and reduced dyskinesias in animal models of Parkinson's disease, suggesting their potential for repurposing to manage symptoms in men with PD.

This study found that isoallopregnanolone reduced stress-induced tic-like behaviors and sensorimotor gating deficits in a mouse model of Tourette syndrome, suggesting potential therapeutic properties comparable to existing treatments like haloperidol and finasteride.

This study observed that minimal doses of the arotinoid RO 13-6298 successfully treated two cases of severe psoriasis and psoriatic arthritis unresponsive to traditional therapies, despite some side effects.

This report discusses a case of localized hypertrichosis that developed after an elderly male with Alzheimer's disease started oral rivastigmine therapy, suggesting a potential link between the drug and hair growth.

This article provides regulatory updates, legal briefs, and industry news, reporting no new clinical findings.

This article compares cabergoline and bromocriptine for treating hyperprolactinemic amenorrhea and reports no specific findings.

This study found that cromakalim and pinacidil significantly inhibited porcine detrusor muscle contractions, suggesting these ATP-sensitive potassium channel openers may have potential in treating certain bladder diseases.

This review discusses the potential role of steroid 5α-reductase inhibitors in treating neuropsychiatric disorders related to dopaminergic hyperreactivity but reports no new clinical results.

This study found that acute sleep deprivation enhanced 5α-reductase expression and activity in the rat prefrontal cortex, and finasteride treatment reduced associated psychosis- and mania-like behaviors.

This study found that Dutasteride, a 5α-reductase inhibitor, demonstrated neuroprotective effects by preventing the MPTP-induced decline of dopaminergic markers in a Parkinson's disease mouse model.

This study found that finasteride blocked the progesterone-induced increase in spike-wave discharges in rats, suggesting that this effect of progesterone is mediated by its metabolite allopregnanolone.

This case report suggests that long-acting injectable risperidone may induce hirsutism in some patients, and clinicians should monitor for this potential side effect when prescribing this antipsychotic.

This study found that dutasteride may help prevent enteric neuronal damage in an animal model of Parkinson's disease, highlighting its potential for drug repurposing to address neuroinflammation.

This study suggests that finasteride may inhibit the enzyme phenylethanolamine N-methyltransferase, which could contribute to its sexual and psychological side effects.

Blocking CYP17A1 enzyme may help improve certain brain function issues related to dopamine.

This review discusses the role of neuro(active)steroids, particularly those in the 5α reductase pathway, in modulating dopamine signaling and their impact on neuropsychiatric disorders characterized by dopamine imbalances, including addiction, schizophrenia, and Parkinson's Disease.

Propranolol affects heart rate and renin levels in minoxidil-treated patients.

This study found that inhibiting the enzyme 5α-reductase with finasteride counteracted stress-induced prepulse inhibition deficits in socially isolated rats by altering neuroactive steroid concentrations in the brain.
