In recent years, epidemiological, clinical, and biological evidence has drawn the attention on the influence of sex and gender on Alzheimer's disease (AD). Nevertheless, not enough attention has been paid to their impact on treatment outcomes. The present study is aimed at systematically retrieve, review and discuss data coming from available randomized placebo-controlled trials (RCTs) on currently marketed treatments for AD (i.e., cholinesterase inhibitors [ChEIs] and memantine) in order to describe possible sex and gender differences in their efficacy, safety and tolerability...

INTRODUCTION: Although four kinds of Alzheimer's disease (AD) drugs are available at present there was only one drug until 2011 in Japan. This study aimed to elucidate prescription trends of these medications for AD in Japanese outpatients before and after the new drug releases in 2011. METHODS: This descriptive study of pharmacy claims databases analyzed outpatient prescription data from community pharmacies across Japan. The study patients were 20 years or older and first administered medications for AD (donepezil, memantine, rivastigmine, or galantamine) between January 2010 and September 2014...

Age-dependent memory deterioration has been well documented and yet an increase in rat hippocampal LTP upon aging has been reported. This poses the question of whether the enhanced LTP is a cause or an attempt to compensate the memory deficits described in aged rats. Hippocampal slices from young, adult and aged Wistar rats were pre-incubated, with an NMDA receptor (NMDAR) antagonist, memantine (1 μM, 4 h), and hippocampal LTP was evaluated. The results show that memantine significantly decreases the larger LTP magnitude recorded in hippocampal slices from aged rats without compromising LTP recorded in slices from young and adult animals...

Alzheimer's disease (AD) is the most common cause of dementia in the elderly. Pharmacological treatment of AD includes Anticholinesterase Inhibitors (AChEIs) for mild-moderate AD, and memantine for severe AD. These drugs provide mainly symptomatic short-term benefits without clearly influencing the progression of the disease. Pioglitazone (AD4833) is an insulin sensitizer of the thiazolidinedione class of nuclear Peroxisome-Proliferator Activated Receptor γ (PPARγ) agonists. It binds to PPARγ, affecting gene transcription and reducing inflammation...

Early use of memantine in the treatment of Lewy body dementia (LBD) is a common type of major neurocognitive disorder (NCD), which is difficult to treat. The use of memantine can be an early treatment strategy. This is illustrated by a case of an 80-year-old patient whose cognition, motor skills and perception disorders reacted favourably to treatment with memantine. The beneficial effect, however, was soon lost after the treatment was discontinued, but reappeared after the medication was reintroduced.

Memantine is a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist used in the treatment of moderate to severe dementia including the symptoms of Alzheimer's disease (AD). It is administered orally but compliance, swallowing problems and the routine use of multiple medications in elderly AD patients means that an alternative route of administration would be of interest. The aim of the present study was to develop memantine hydrochloride occlusive transdermal therapeutic systems (TTS) for passive and iontophoretic delivery across the skin...

Alzheimer's disease (AD) is a progressive neurodegenerative disorder and currently there is no efficient treatment. The classic drug-design strategy based on the "one-molecule-one-target" paradigm was found to be ineffective in the case of multifactorial diseases like AD. A novel multi-target-directed ligand strategy based on the assumption that a single compound consisting of two or more distinct pharmacophores is able to hit multiple targets has been proposed as promising. Herein, we investigated 7-methoxytacrine - memantine heterodimers developed with respect to the multi-target-directed ligand theory...

BACKGROUND: A large, prospective, 2-year, randomized study in patients with mild-to-moderate Alzheimer's disease or mixed dementia demonstrated reductions in mortality and cognitive/functional decline in galantamine-treated patients. A post-hoc analysis was conducted to study the effect of (the presence or absence of) concomitant memantine use on treatment outcome. METHODS: Randomized patients (N = 2045) were divided into subgroups based on memantine use. Analyses included demographic and clinical characteristics (age, nursing home placement, Mini-Mental State Examination (MMSE) and Disability Assessment for Dementia (DAD) scores) and mortality endpoints...

Ischemia is one of the most prominent risk factors of neurodegenerative diseases such as Alzheimer's disease. The effects of oxygen and glucose depletion in hippocampal tissue due to ischemia can be mimicked in vitro using the oxygen and glucose deprivation (OGD) model. In this study, we applied OGD on acute rat hippocampal slices in order to design an elementary yet quantitative histological technique that compares the neuroprotective effects of (l)-carnitine to known neuroprotectors, such as the N-methyl-d-aspartate (NMDA) receptor antagonist memantine and the gamma-aminobutyric acid (GABA)-B receptor agonist baclofen...

Whether Neo-adjuvant chemotherapy can affect patients' postoperative brain function is not clear. In this study, we investigated the effect of preoperative cisplatin treatment on postoperative cognitive function and its possible mechanism in rats. Moreover, we also tested whether the NMDAR inhibitor memantine could attenuate cisplatin-induced alterations. 12-month-oldSprague-Dawley rats randomly received an intraperitoneal injection of either cisplatin once a week at a dose of 3mg/kg for three consecutive weeks or an equivalent volume of normal saline...

RATIONALE: The N-methyl-D-aspartate (NMDA) receptor has been recently identified as an important mediator of impulsive choice, as assessed in delay discounting. Although discounting is independently influenced by sensitivity to reinforcer magnitude and delayed reinforcement, few studies have examined how NMDA receptor ligands differentially affect these parameters. OBJECTIVES: The current study examined the effects of various NMDA receptor ligands on sensitivity to reinforcer magnitude and delayed reinforcement in a delay-discounting procedure...

A developing body of data has drawn attention to the N-methyl-d-aspartate (NMDA) receptor antagonists as potential drugs for the treatment of major depressive disorder (MDD). We investigated the possibility of synergistic interactions between the antidepressant sertraline with the uncompetitive NMDA receptor antagonist, memantine. The present study was aimed to evaluate behavioural and molecular effects of the chronic treatment with memantine and sertraline alone or in combination in rats. To this aim, rats were chronically treated with memantine (2...

Current pharmacological recommendations for the treatment of Alzheimer's disease (AD) include the cholinesterase inhibitors and the N-methyl-D-aspartate antagonist, memantine. However, these medications only manage symptoms of AD, and do not target Aβ plaques and neurofibrillary tangles. As such, there is a need to develop effective and safe disease modifying treatments that directly target AD pathology and alter the course of AD progression. Areas covered: This review evaluates ongoing phase 2 and 3 clinical trials, as well as those completed or published over the past five years...

The capability of memantine, a noncompetitive antagonist of the NMDA receptors, to prevent impairments of cognitive functions in rats was investigated in the lithium-pilocarpine model of epilepsy. After status epilepticus, rats exhibited impaired exploratory behavior and spatial memory, and a decline of extinction of orienting behavior. Memantine administration prevented these disturbances. Thus, the blockade of the NMDA receptors immediately after status epilepticus allowed prevention of the development of the possible cognitive impairments...

Currently available data indicate superior therapeutic effects of combination treatment for Alzheimer dementia with memantine and acetylcholine esterase inhibitors in certain clinical contexts. Out of five randomized, placebo-controlled, double-blind trials two showed superior therapeutic effects in comparison to monotherapy with acetylcholinesterase inhibitors regarding various domains. Recently published meta-analyses and cost-benefit analyses also showed positive results. Recently published German guidelines for dementia treatment also take these new data into account and recommend combination treatment in patients with severe dementia on stable donepezil medication...

Phantom limb pain (PLP) occurs in up to 85% of patients who have undergone an amputation and remains difficult to treat. Memantine is a N-Methyl-d-aspartate receptor antagonist that has shown benefit in pain syndromes. The objective of this systematic review is to evaluate the evidence for the use of memantine in the treatment of acute and chronic PLP. MEDLINE (1956 to May 2016) and Embase (1957 to May 2016) were queried for articles that characterized the clinical outcomes of patient(s) treated with memantine for PLP...

WHAT IS KNOWN AND OBJECTIVE: Current treatments for depressive disorders are far from optimum. This study was planned to evaluate possible antidepressant effects and safety of memantine, a selective N-methyl-d-aspartate receptor antagonist, in humans. METHODS: Sixty-six outpatients with the diagnosis of moderate-to-severe major depressive disorder, based on DSM-V diagnostic criteria, were recruited to participate in a parallel, randomized, controlled trial. Sixty-two participants completed 6 weeks of treatment with either memantine (20 mg/day) plus sertraline (200 mg/day) or placebo plus sertraline (200 mg/day)...
