Bladder hyperreflexia is a common non-motor feature of Parkinson's disease. We now report on the contractility of the isolated primate detrusor strips devoid of nerve input and show that following MPTP, the amplitude and frequency of spontaneous contraction was increased. These responses were unaffected by dopamine D1 and D2 receptor agonists A77636 and ropinirole respectively. Contractions by exogenous carbachol, histamine or ATP were similar and no differences in the magnitude of noradrenaline-induced relaxation were seen in detrusor strip obtained from normal and MPTP-treated common marmosets (Callithrix jacchus)...

Gum Ghatti (GG) is a water soluble complex polysaccharide obtained from Anogeissus latifolia. Due to its non toxic and excellent emulsifying characteristics, it was widely used in different pharmaceutical preparations. Currently another facet was explored for its utility as release retardant polymer in oral controlled drug delivery system. As GG solely was incapable of forming microspheres therefore modification of GG to Sodium carboxymethyl (NaCMGG) derivative was done by carboxymethylation process and its gel forming capacity was explored by the use of trivalent cation (Aluminium chloride) which results into complete microbead system in a complete aqueous environment for controlled delivery of Ropinirole Hydrochloride (RHCl)...

Parkinson's disease (PD) patients are at a higher risk of malnutrition. The prevalence has been estimated to 0-24%, while 3%-60% of PD patients are reported to be at risk of malnutrition. To date, there is no clear explanation for malnutrition in these patients. The aim of this study was to determine the prevalence of malnutrition and to analyze factors that influence its appearance. The Mini Nutritional Assessment (MNA) was used to determine normal nutritional status; at risk of malnutrition; and already malnourished status...

Ramón Cacabelos
Parkinson's disease (PD) is the second most important age-related neurodegenerative disorder in developed societies, after Alzheimer's disease, with a prevalence ranging from 41 per 100,000 in the fourth decade of life to over 1900 per 100,000 in people over 80 years of age. As a movement disorder, the PD phenotype is characterized by rigidity, resting tremor, and bradykinesia. Parkinson's disease -related neurodegeneration is likely to occur several decades before the onset of the motor symptoms. Potential risk factors include environmental toxins, drugs, pesticides, brain microtrauma, focal cerebrovascular damage, and genomic defects...

Phencyclidine (PCP), a noncompetitive N-methyl d-aspartate (NMDA) receptor antagonist, provides the most complete pharmacologic model of schizophrenia in humans and animals. Acute PCP causes hyperlocomotion, disrupts prepulse inhibition (PPI), and increases social avoidance in rats. We have previously shown that repeated treatment with the dopamine (DA) D2-like receptor agonists, quinpirole or ropinirole, prevents agonist-induced PPI disruption. In the present study, we examined whether repeated ropinirole treatment similarly attenuates the effects of PCP in a more complete model of schizophrenia symptoms and examined the effect of repeated D2-like agonist treatment on locomotion, PPI, and social interaction after acute PCP challenge...

Levodopa-induced dyskinesia (LID) is a disabling motor complication occurring in Parkinson's disease patients (PD) after long-term l-DOPA treatment. Although its etiology remains unclear, there is accumulating evidence that LID relies on an excessive dopamine receptor transmission, particularly at the downstream signaling of D1 receptors. We previously reported that the pharmacological blockade of 5-alpha reductase (5AR), the rate limiting enzyme in neurosteroids synthesis, rescued a number of behavioral aberrations induced by D1 receptor-selective and non-selective agonists, without inducing extrapyramidal symptoms...

OBJECTIVE: To make evidence-based recommendations regarding restless legs syndrome (RLS) management in adults. METHODS: Articles were classified per the 2004 American Academy of Neurology evidence rating scheme. Recommendations were tied to evidence strength. RESULTS AND RECOMMENDATIONS: In moderate to severe primary RLS, clinicians should consider prescribing medication to reduce RLS symptoms. Strong evidence supports pramipexole, rotigotine, cabergoline, and gabapentin enacarbil use (Level A); moderate evidence supports ropinirole, pregabalin, and IV ferric carboxymaltose use (Level B)...

BACKGROUND: Restless legs syndrome (RLS) is defined as the spontaneous movement of the limbs (mainly legs) associated with unpleasant, sometimes painful sensation which is relieved by moving the affected limb. Prevalence of RLS among people on dialysis has been estimated between 6.6% and 80%. RLS symptoms contribute to impaired quality of life and people with RLS are shown to have increased cardiovascular morbidity and mortality.Various pharmacological and non-pharmacological interventions have been used to treat primary RLS...

PURPOSE: Some studies have suggested a potential risk of heart failure in patients with Parkinson's disease receiving dopamine (DA) agonists. However, the results are conflicting. We used VigiBase®, the World Health Organization (WHO) Global Individual Case Safety Reports (ICSRs) database, to investigate a potential signal strengthening of heart failure with DA agonists in Parkinsonian patients older than 45 years. METHODS: A case/non-case (disproportionality) analysis was performed in Vigibase® using ICSRs registered between 1978 and May 2016...
