The objective of the current review was to update the previous evidence-based medicine review of treatments for restless legs syndrome published in 2008. All randomized, controlled trials (level I) with a high quality score published between January 2007 and January 2017 were reviewed. Forty new studies qualified for efficacy review. Pregabalin, gabapentin enacarbil, and oxycodone/naloxone, which did not appear in the previous review, have accrued data to be considered efficacious. Likewise, new data enable the modification of the level of efficacy for rotigotine from likely efficacious to efficacious...

Over 300 chiral drug substances lack official United States Pharmacopeia (USP) methods for the enantiomeric purity determination. Because enantiomeric analysis typically requires specialized methods for each drug compound, developing protocols for each of these 300+ substances would be an expensive and laborious endeavor. Alternatively, if a detector capable of determining the enantiomeric composition without chiral separation could be used with certain drug compounds, this could be implemented relatively rapidly into official testing monographs...

OBJECTIVE: This study aimed to systematically review the effects of currently prescribed antiparkinson medication on cognition in patients with mild-to-moderate Parkinson's disease (PD) who were either cognitively intact or mildly impaired. METHODS: English- and French-language studies published between 1969 and 2017 were accessed via MedLine, PsychNET, EMBASE and EBSCO databases. Methodological quality (MQ) was evaluated with the quality assessment instrument of the Cochrane Collaboration Depression, Anxiety and Neurosis Review (scores from 0% to 44% indicate very low quality; scores from 45% to 64% indicate low quality; scores from 65% to 84% indicate medium quality; and scores from 85% to 100% indicate high quality)...

The main adverse effects of dopaminergic drugs used in Parkinson's disease are hypotension, somnolence, hallucinations and impulse control disorder. Less common is leg edema. We report on a 68-year-old male receiving levodopa and pramipexole consulting for severe leg edema lasting two years, whose etiology was not ascertained with multiple lab tests. This edema subsided substantially when pramipexole was discontinued and the dose of levodopa was increased to treat motor symptoms.

The antiparkinsonian ropinirole and pramipexole are D3 receptor- (D3R-) preferring dopaminergic (DA) agonists used as adjunctive therapeutics for the treatment resistant depression (TRD). While the exact antidepressant mechanism of action remains uncertain, a role for D3R in the restoration of impaired neuroplasticity occurring in TRD has been proposed. Since D3R agonists are highly expressed on DA neurons in humans, we studied the effect of ropinirole and pramipexole on structural plasticity using a translational model of human-inducible pluripotent stem cells (hiPSCs)...

STUDY OBJECTIVES: The objective of this study is to assess adherence and persistence of ropinirole, pramipexole, and gabapentin; to investigate factors associated with non-adherence and non-persistence in restless legs syndrome (RLS) patients. METHODS: We used the 2008-2014 Marketscan® Research Databases to conduct a retrospective data analysis. The study included newly diagnosed RLS patients who initiated ropinirole, pramipexole, or gabapentin therapy. During 365 days of follow-up, mean medication possession ratios (MPRs) for adherence and the proportion of adherent users were calculated...

Parkinson's disease (PD) is one of the most severe neurodegenerative diseases with unknown pathogenesis and currently unsuccessful therapies. Recently, neuroprotection via sphingosine-1-phosphate (S1P)-dependent signalling has become a promising target for the treatment of neurodegenerative disorders. Our previous study demonstrated down-regulation and inhibition of the S1P-synthesizing enzyme sphingosine kinase 1 (SPHK1) in a PD cellular model. Moreover, we have previously identified a neuroprotective effect of fingolimod (FTY720), a first S1P receptor modulator utilized in the clinic...

Effective treatment of Parkinson's disease (PD) involves administration of therapeutic agents with complementary mechanisms of action in order to replenish, sustain or substitute endogenous dopamine. The objective of this study was to investigate anodal co-iontophoresis of pramipexole (PRAM; dopamine agonist) and rasagiline (RAS; MAO-B inhibitor) in vitro and in vivo. Passive permeation of PRAM and RAS (20 mM each) across porcine skin after 6 h was 15.7 ± 1.9 and 16.0 ± 2.9 µg/cm2 , respectively...

Background: The altered expression and function of dopamine receptor D3 (D3R) in patients and animal models have been correlated with depression disease severity. However, the morphological alterations and biological effects of D3R in the brain after inflammation-induced depressive-like behavior remain elusive. Methods: In the present study, we ascertained the changes of D3R expression in the brain regions after depressive-like behavior induced by peripheral administration of lipopolysaccharide (LPS)...

BACKGROUND: Impulse control disorders (ICDs) comprise abnormal behaviors frequently found in patients with Parkinson's disease (PD) receiving antiparkinsonian medication. ICDs in PD would develop when dopaminergic treatment overstimulates the dopamine receptor D3 (DR3). Here we studied whether DR3 gene (DRD3) is associated to ICD in PD patients with early-onset (EOPD). METHODS: We performed association analysis of the rs6280 DRD3 single nucleotide variation (SNV) (Ser9Gly) in a clinical sample of 126 non early-onset PD (NEOPD) and 73 EOPD (age at onset < 45)...

Parkinson's disease is prevalent worldwide but mainly affects the elderly and is rarely seen in women of child-bearing age. The clinical signs and symptoms, the physiological changes of pregnancy, and drug interactions, pose unique challenges for the anaesthetic management of patients with Parkinson's disease who present for delivery. A 36-year-old primigravid woman at 36 weeks' gestation, with Parkinson's disease, presented for pre-anaesthesia assessment prior to elective caesarean section. Her Parkinson's disease had been diagnosed four years previously and was treated with Sinemet (levodopa/carbidopa) and pramipexole...

Julio Quezada, Keith A Coffman
Tourette syndrome (TS) is a neurodevelopmental disorder of unknown etiology characterized by spontaneous, involuntary movements and vocalizations called tics. Once thought to be rare, TS affects 0.3-1% of the population. Tics can cause physical discomfort, emotional distress, social difficulties, and can interfere with education and desired activities. The pharmacologic treatment of TS is particularly challenging, as currently the genetics, neurophysiology, and neuropathology of this disorder are still largely unknown...

Restless legs syndrome (RLS) is commonly treated with the dopamine agonists pramipexole, and rotigotine, which target the inhibitory dopamine receptor subtype D3R. While initially highly effective, these compounds lose their efficacy in treating RLS over time, and long-term therapy regularly leads to a worsening of the symptoms (augmentation). This dopamine agonist-induced augmentation has become a prime concern in the treatment of RLS, and while alternate therapies are being proposed, the mechanisms leading to augmentation remain opaque...

BACKGROUND: Spasticity and spasms are distressing features of the upper motor neuron syndrome (UMNS) following spinal cord injuries (SCI) or multiple sclerosis (MS), and have common therapeutic implications. Despite an increase of antispastic drugs and strategies, sometimes up to the surgical implant of intrathecal baclofen pump, some patients still complain of disabling spasms, which poses diagnostic and therapeutic challenges. Although clinically similar, flexor spasms due to pyramidal tract disruption must be clearly differentiated from periodic limb movements (PLM), often accompanying restless leg syndrome (RLS) and occurring during sleep...
