概括
在患有帕金森病痴呆症 (PDD) 的患者中,安布罗克索尔被发现是安全的,并且耐受性良好,证明了目标参与. 然而,该研究并未证实Ambroxol的存在.
科学领域:
- 神经退行性疾病的神经退行性疾病
- 药理学 药理学是指药理学的学科.
- 临床试验中的临床试验.
背景情况:
- 贝塔-葡萄糖核糖酶 (GBA) 的遗传变异是帕金森病痴呆症 (PDD) 的危险因素.
- 增加GBA水平可以降低α-synuclein,这是一种关键蛋白质,与帕金森病有关.
- 安布罗克索尔作为GBA的陪伴者,增强其水平.
研究的目的:
- 评估Ambroxol在PDD患者中的安全性和耐受性.
- 评估Ambroxol在改善或减缓认知衰退方面的疗效.
- 收集关于Ambroxol在PDD中的作用的药理学数据.
主要方法:
- 一个52周,第二阶段,双盲,安慰剂控制,随机的临床试验.
- 纳入标准:50岁以上的PDD患者患有轻度至中度痴呆症,至少在1年前被诊断出来.
- 干预措施:低剂量安布罗克索尔 (525毫克/天),高剂量安布罗克索尔 (1050毫克/天) 或安慰剂.
主要成果:
- 阿姆布罗克索尔是安全的,耐受性良好,与安布罗克索尔组相比,安布罗克索尔组的胃肠道不良事件更多.
- 药理学数据显示,Ambroxol在血和脑脊液中达到治疗度.
- 虽然Ambroxol组的GBA水平升高,但两组之间没有观察到认知结果 (ADAS-Cog-13,CGIC) 的显著差异.

Parkinson's Disease: Treatment
389
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Alzheimer's Disease: Treatment
265
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Peripherally and Centrally Acting Muscle Relaxants: A Comparison
3.7K
Skeletal muscle relaxants can target the central nervous system [CNS] to reduce muscle tension or act directly at the neuromuscular junction to induce temporary paralysis. These two classes of muscle relaxants are called centrally acting muscle relaxants and peripherally acting muscle relaxants. They differ in their action, mechanism, administration route, and clinical uses.
Centrally acting muscle relaxants can be further divided into spasmolytic and antispasmodic drugs. Spasmolytic...
