Download or read book Levodopa pharmacokinetics from stomach to brain written by Maria Nord and published by Linköping University Electronic Press. This book was released on 2019-01-07 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parkinson’s disease (PD) is one of the most common neurodegenerative disorders and it is caused by a loss of dopamine (DA) producing neurons in the basal ganglia in the brain. The PD patient suffers from motor symptoms such as tremor, bradykinesia and rigidity and treatment with levodopa (LD), the precursor of DA, has positive effects on these symptoms. Several factors affect the availability of orally given LD. Gastric emptying (GE) is one factor and it has been shown to be delayed in PD patients resulting in impaired levodopa uptake. Different enzymes metabolize LD on its way from the gut to the brain resulting in less LD available in the brain and more side effects from the metabolites. By adding dopa decarboxylase inhibitors (carbidopa or benserazide) or COMT-inhibitors (e.g. entacapone) the bioavailability of LD increases significantly and more LD can pass the blood-brain-barrier and be converted to DA in the brain. It has been considered of importance to avoid high levodopa peaks in the brain because this seems to induce changes in postsynaptic dopaminergic neurons causing disabling motor complications in PD patients. More continuously given LD, e.g. duodenal or intravenous (IV) infusions, has been shown to improve these motor complications. Deep brain stimulation of the subthalamic nucleus (STN DBS) has also been proven to improve motor complications and to make it possible to reduce the LD dosage in PD patients. In this doctoral thesis the main purpose is to study the pharmacokinetics of LD in patients with PD and motor complications; in blood and subcutaneous tissue and study the effect of GE and PD stage on LD uptake and the effect of continuously given LD (CDS) on LD uptake and GE; in blood and cerebrospinal fluid (CSF) when adding the peripheral enzyme inhibitors entacapone and carbidopa to LD infusion IV; in brain during STN DBSand during oral or IV LD treatment. To conclude, LD uptake is more favorable in PD patients with less severe disease and GE is delayed in PD patients. No obvious relation between LD uptake and GE or between GE and PD stage is seen and CDS decreases the LD levels. Entacapone increases the maximal concentration of LD in blood and CSF. This is more evident with additional carbidopa and important to consider in avoiding high LD peaks in brain during PD treatment. LD in brain increases during both oral and IV LD treatment and the DA levels follows LD well indicating that PD patients still have capacity to metabolize LD to DA despite probable pronounced nigral degeneration. STN DBS seems to increase putaminal DA levels and together with IV LD treatment also increases LD in brain possibly explaining why it is possible to decrease LD medication after STN DBS surgery. Parkinsons sjukdom (PS) är en av de vanligaste s.k. neurodegenerativasjukdomarna och orsakas av förlust av dopamin(DA)producerande nervceller i hjärnan. Detta orsakar motoriska symptom såsom skakningar, stelhet och förlångsammade rörelser. Levodopa (LD) är ett ämne, som kan omvandlas till DA i hjärnan och ge symptomlindring och det är oftast förstahandsval vid behandling av patienter med PS. Flera faktorer påverkar tillgängligheten av LD, bl.a. den hastighet som magsäcken tömmer sig med och denna verkar förlångsammad hos personer med PS vilket ger sämre tillgänglighet av LD i blodet och därmed i hjärnan. LD bryts även ner i hög grad av olika enzym ute i kroppen vilket leder till mindre mängd LD som hamnar i hjärnan och till fler nedbrytningsprodukter som orsakar biverkningar. Tillägg av enzymhämmare leder till ökad mängd LD som kan nå hjärnan och omvandlas till DA. Det anses viktigt att undvika höga toppar av LD i hjärnan då dessa verkar bidra till utvecklandet av besvärliga motoriska komplikationer hos patienter med PS. Om LD ges mer kontinuerligt, exempelvis som en kontinuerlig infusion in i tarmen eller i blodet, så minskar dessa motoriska komplikationer. Inopererande av stimulatorer i vissa delar av hjärnan (DBS) har också visat sig minska dessa motoriska komplikationer och även resultera i att man kan minska LD-dosen. Huvudsyftet med den här avhandlingen är att studera LD hos patienter med PS; i blod och fettvävnad då LD ges i tablettform och se om det finns något samband med LD-upptag och hastigheten på magsäckstömningen (MT) och om kontinuerligt given LD påverkar LD-upptaget eller MT; i blod och i ryggmärgsvätska då enzymhämmarna entakapon och karbidopa tillsätts LD; i hjärna vid behandling med DBS och då LD ges både som tablett och som infusion i blodet. Sammanfattningsvis kan vi se att LD-upptaget är mer gynnsamt hos patienter med PS i tidigare skede av sjukdomens komplikationsfas. MT är förlångsammad hos patienter med PS och det är inget tydligt samband mellan LD-upptag och MT eller mellan MT och sjukdomsgrad. Kontinuerligt given LD minskar LDnivåerna. Enzymhämmaren entakapon ökar den maximala koncentrationen av LD i blod och ryggmärgsvätska och effekten är mer tydlig vid tillägg av karbidopa vilket är viktigt att ta i beaktande vid behandling av PS för att undvika höga toppar av LD i hjärnan. LD ökar i hjärnan då man behandlar med LD i tablettform och som infusion i blodet och DA-nivåerna i hjärnan följer LD väl vilket visar på att patienter med PS fortfarande kan omvandla LD till DA trots trolig uttalad brist av de DA-producerande nervcellerna i hjärnan. DBS verkar öka DA i vissa områden i hjärnan och tillsammans med LD-infusion i blodet verkar det även öka LD i hjärnan och det kan förklara varför man kan sänka LDdosen efter DBS-operation.

This book was released on 2021-06-12 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 50 years have passed since the use of L-dopa in the palliative treatment of Parkinson's disease, but it remains the most common treatment despite inducing severe side effects such as dyskinesia after 4–6 years of use. Numerous preclinical investigations based on endogenous neurotoxin models have promised various therapies for Parkinson's disease, but these efforts have failed when attempting to transfer these successful results to preclinical studies. Although several publications have warned of these failures, the scientific community remains mostly unaware, and there is a need to focus their efforts on potential therapeutics that can slow or halt development of the disease.Clinical Studies and Therapies in Parkinson's Disease: Translations from Preclinical Models analyzes preclinical models based on exogenous neurotoxins and why they have failed. Neuroscientists, neurologists, and neuropharmacologists will benefit greatly from the book's discussion of these newer models, their benefits, and the need for their implementation. This book also provides the basic concepts of dopamine metabolism for students taking courses in neurochemistry, neuroscience, neuropharmacology, biochemistry, and medicine. - Reviews Parkinson's disease classification, pharmacological therapies, and nonmotor and motor symptoms - Analyzes preclinical models of Parkinson's disease therapies based on exogenous neurotoxins and why they have failed - Reviews genetic preclinical models based on genetic mutations and endogenous neurotoxins - Proposes a more physiological model directly related to the metabolism of dopaminergic neurons - Provides the basic concepts and mechanisms of dopamine metabolism

This book was released on 1999-05-11 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expert clinicians and basic scientists with a special interest in Parkinson’s disease review the current state of science and clinical therapeutics of the disease. Therefore these articles represent an authorative review of the current state of knowledge regarding preclinical course and symptomatology, subtypes with their impact on the pathology, genetic alterations, novel mechanisms of neuronal cell death, diagnostic tools and old and novel therapeutic approaches with respect to neuroprotection and neuroregeneration in Parkinson’s disease. Particular emphasis has been placed on a novel antiparkinsonian drug called budipine with various modes of action also influencing altered non dopaminergic systems in Parkinson’s disease. It is evident, that many questions on the cause, course and treatment of Parkinson’s disease are still unanswered and therefore the ideal way to treat a parkinsonian patient remains to be defined.

Download or read book Non Motor Symptoms of Parkinson s Disease written by K. Ray Chaudhuri and published by Oxford University Press, USA. This book was released on 2014 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Patients with Parkinson's disease (PD) are known to suffer from motor symptoms of the disease, but they also experience non-motor symptoms (NMS) that are often present before diagnosis or that inevitably emerge with disease progression. The motor symptoms of Parkinson's disease have been extensively researched, and effective clinical tools for their assessment and treatment have been developed and are readily available. In contrast, researchers have only recently begun to focus on the NMS of Parkinson's Disease, which are poorly recognized and inadequately treated by clinicians. The NMS of PD have a significant impact on patient quality of life and mortality and include neuropsychiatric, sleep-related, autonomic, gastrointestinal, and sensory symptoms. While some NMS can be improved with currently available treatments, others may be more refractory and will require research into novel (non-dopaminergic) drug therapies for the future. Edited by members of the UK Parkinson's Disease Non-Motor Group (PD-NMG) and with contributions from international experts, this new edition summarizes the current understanding of NMS symptoms in Parkinson's disease and points the way towards future research.

Download or read book Run in the Light written by John Mitrofanis and published by Morgan & Claypool Publishers. This book was released on 2019-08-05 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parkinson's disease is a neurological disorder with cardinal motor signs of resting tremor, bradykinesia and lead-pipe rigidity. In addition, many patients display non-motor symptoms, including a diminished sensation of smell, gastrointestinal problems, various disorders of sleep and some cognitive impairment. These clinical features - particularly the motor signs - manifest after a progressive death of many dopaminergic neurones in the brain. Although currently available, conventional therapies can reduce the signs of the disease, the progression of this neuronal death has proved difficult to slow or stop, and the condition is relentlessly progressive. Hence, there is a real need to develop a treatment that is neuroprotective, one that slows the pathology of the disease effectively. At present, there are several neuroprotective therapies in the experimental pipeline, but these are for the patients of tomorrow. This book focuses on two therapies that are readily available for the patients of today. They involve the use of exercise and light (i.e. photobiomodulation, the use of red to infrared light therapy (λ=600-1070nm) on body tissues). The two therapies are tied together in several ways. First, in animal models of Parkinson's disease, they each have been shown to offer the key feature of neuroprotection, stimulating a series of built-in protective mechanisms within the neurones, that helps their survival, to self-protect and/or self-repair. There are also some promising indications of neuroprotection and many beneficial outcomes in parkinsonian patients. Further, both exercise and light therapies are similar in that they are non-invasive and safe to use, with no known adverse side-effects, making their combination with the conventional therapies, such as dopamine replacement drug therapy and deep brain stimulation, all the more feasible. Given the heterogeneity of Parkinson's disease in humans, tackling the condition from a range of different angles - with a number of different therapies - would only serve to enhance the positive outcomes. This book considers the use of exercise and light therapies, proposing that they have the potential to make a powerful "dynamic duo", offering a most effective neuroprotective treatment option to patients.
