OBJECTIVE
Scopolamine butylbromide (SB), a muscarinic receptor antagonist, is used commonly in gastric X-ray examination in the physical check-up in Japan. This study describes clinical features of SB-induced headache.
METHODS
SB-induced headache was defined as headache that started within 20
Scopolamine (Sco) can induce amyloid β (Aβ) deposition, oxidative stress, synaptic dysfunction, and learning/memory impairment as observed in Alzheimer's disease (AD), the most common form of dementia affecting more than 25 million elderly people worldwide. Herein we explored the protective effect
Major depressive disorder (MDD) is a recurring psychiatric illness that causes substantial health and socioeconomic burdens. Clinical reports have revealed that scopolamine, a nonselective muscarinic acetylcholine receptor antagonist, produces rapid antidepressant effects in individuals with MDD.
Humanin, a short bioactive peptide, inhibits cell death in a variety of cell-based death models through Humanin receptors in vitro. In vivo, Humanin ameliorates both muscarinic receptor antagonist-induced memory impairment in normal mice and memory impairment in Alzheimer's disease (AD)-relevant
Depression is a common, debilitating mood disorder, but currently available antidepressants have several major drawbacks. Both ketamine and scopolamine attract more and more attention due to their rapid and sustained antidepressant activities. However, the molecular and cellular mechanism that
Current medications for depression typically require weeks of treatment before significant clinical improvement is observed, and are only effective in a relatively small subset of patients. Recent human clinical studies have demonstrated that ketamine, an NMDA receptor antagonist, and scopolamine, a
We investigated the effects of zerumbone (1 and 10 mg/kg) against hyperactivity, anxiety and memory impairment in scopolamine-induced dementia in Sprague-Dawley rats.Open field tests, elevated plus maze and Morris water maze were performed to assess general Vascular endothelial dysfunction plays a key role in the pathogenesis of Alzheimer's disease (AD). Patients with AD have displayed decreased circulating endothelial progenitor cells (EPCs) which repair and maintain the endothelial function. Transplantation of EPCs has emerged as a promising approach
The development of agents that affect two or more relevant targets has drawn considerable attention in treatment of AD. Diallyl disulfide (DADS), an active principle of garlic, has been reported to prevent APP processing by amyloidogenic pathway. Recently, we have reported a new series of DADS
Scopolamine produces rapid and significant symptom improvement in patients with depression, and most notably in patients who do not respond to current antidepressant treatments. Scopolamine is a nonselective muscarinic acetylcholine receptor antagonist, and it is not known which one or more of the
Some clinical studies indicate that scopolamine may induce a rapid antidepressant effect. Although scopolamine is a muscarinic antagonist, it seems that not only cholinergic but also glutamatergic and GABAergic systems might be involved in the mechanism of its antidepressant activity in animal
Clinical studies have shown that the muscarinic receptor antagonist scopolamine induces a potent and rapid antidepressant effect relative to conventional antidepressants. However, potential undesirable effects, including memory impairment, partially limit the use of scopolamine in psychiatry. In the
The Salicornia europaea L. (SE) plant is a halophyte that has been widely consumed as a seasoned vegetable, and it has been recently reported to counteract chronic diseases related to oxidative and inflammatory stress. In this study, we performed an initial phytochemical analysis with in vitro
Embelin (2,5-dihydroxy-3-undecyl-1,4-benzoquinone) is one of the active components (2.3%) found in Embelia ribes Burm fruits. As determined via in vitro AChE inhibition assay, embelin can inhibit the acetylcholinesterase enzyme. Therefore, embelin can be utilized as a therapeutic compound, after
