Mean caregiver age was 59.8±14.4 years and 70.9% were women. They spent 10.0±7.1hours per day providing care and 79.8% lived with the patient. Patch instructions were described as easy to follow by 97.1% of the caregivers and 92.1% of them rated patch application as easy or very easy. The most commonly cited disadvantage was adhesion problems (26.8%). Discontinuation of treatment was due to cutaneous reactions in most cases. Overall, 76.5% of the caregivers were satisfied or very satisfied with transdermal treatment and 77.4% considered that its interference with daily activities was minimal or null. The patch was preferred to oral treatment by 94.3% of caregivers. Clinical Global Impression of Change ratings improved according to 61.3% of the caregivers and 53% of the investigators. Few caregivers reported medication forgetfulness.

Cholinesterase (ChE) inhibitors represent the standard therapeutic approach to the treatment of Alzheimer's disease (AD). However, a proportion of patients experience lack or loss of therapeutic benefit with an initial agent, or discontinue due to safety/tolerability issues. In many instances, no alternative treatment is offered once the initial agent has been stopped. Thus, for many patients, the total duration of treatment is relatively short in comparison with the chronic nature of AD. Switching medications is a common therapeutic strategy within many drug classes across many clinical areas following a lack/loss of efficacy or safety/tolerability problems, and is also an increasingly important concept in the management of AD with ChE inhibitors. A number of open-label studies, where patients were switched from donepezil to rivastigmine, have indicated that approximately 50% of patients experiencing a lack/loss of efficacy with donepezil (a selective acetylcholinesterase [AChE] inhibitor) respond to subsequent treatment with rivastigmine (a dual AChE and butyrylcholinesterase inhibitor). In these studies, rivastigmine was well tolerated, and the occurrence of safety/tolerability problems with donepezil was not predictive of similar problems with rivastigmine. In the summer of 2002, leading neurologists and psychiatrists attended a medical experts meeting to discuss the clinical importance of switching ChE inhibitors in AD. The expert panel examined available clinical data, shared clinical experiences, and discussed current clinical guidelines for switching. The panel also aimed to reach consensus on 'whom to switch', 'when to switch' and 'how to switch'. The key findings from that meeting are reported in this review.

Rivastigmine is a very important drug prescribed for the treatment of Alzheimer's disease (AD) symptoms. It is a dual inhibitor, in that it inhibits both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). For our screening program on the discovery of new rivastigmine analogue hits for human butyrylcholinesterase (hBuChE) inhibition, we investigated the interaction of this inhibitor with BuChE using the complimentary approach of the biophysical method, saturation transfer difference (STD)-NMR and molecular docking. This allowed us to obtain essential information on the key binding interactions between the inhibitor and the enzyme to be used for screening of hit compounds. The main conclusions obtained from this integrated study was that the most dominant interactions were (a) H-bonding between the carbamate carbonyl of the inhibitor and the NH group of the imidazole unit of H434, (b) stacking of the aromatic unit of the inhibitor and the W82 aromatic unit in the choline binding pocket via π-π interactions and (c) possible CH/π interactions between the benzylic methyl group and the N-methyl groups of the inhibitor and W82 of the enzyme.

With ageing of populations, the worldwide population of persons with dementia will reach over 81 million by 2040, of which the most common cause is Alzheimer's disease. In recent years, there have been major advances in the understanding of its pathogenesis, methods to diagnose it, and treatment. Magnetic resonance brain imaging, cerebrospinal fluid biomarkers, and Pittsburgh compound B and fluorodeoxyglucose positron emission tomography of the brain can facilitate an accurate diagnosis of Alzheimer's disease in its early stage, and diagnose the mild cognitive impairment stage of Alzheimer's disease. At present, only symptomatic but not disease-modifying drug treatments are available. Donepezil, rivastigmine and galantamine are the currently approved cholinesterase inhibitors for the treatment of mild, moderate, and severe Alzheimer's disease. Overall, cholinesterase inhibitors show beneficial effects on cognition, activity of daily living, behaviour, and overall clinical rating. Memantine is another symptomatic treatment for moderate-to-severe Alzheimer's disease patients. It has a small beneficial effect on cognition, activity of daily living, behaviour, and overall clinical rating. Vitamin E has antioxidant properties, and may be used in some Alzheimer's disease patients without vascular risk factors. Concurrent non-pharmacological and psychosocial management of patients and their caregivers have a very important role. Disease-modifying therapies are still under development, whilst immunotherapy may be a viable option in the near future.

The cholinergic system plays important roles in both learning and addiction. Medications that modify cholinergic tone can have pronounced effects on behaviors reinforced by natural and drug reinforcers. Importantly, enhancing the action of acetylcholine (ACh) in the nucleus accumbens and ventral tegmental area (VTA) dopamine system can either augment or diminish these behaviors. A threshold model is presented that can explain these seemingly contradictory results. Relatively low levels of ACh rise above a lower threshold, facilitating behaviors supported by drugs or natural reinforcers. Further increases in cholinergic tone that rise above a second upper threshold oppose the same behaviors. Accordingly, cholinesterase inhibitors, or agonists for nicotinic or muscarinic receptors, each have the potential to produce biphasic effects on reward behaviors. Pretreatment with either nicotinic or muscarinic antagonists can block drug- or food- reinforced behavior by maintaining cholinergic tone below its lower threshold. Potential threshold mediators include desensitization of nicotinic receptors and biphasic effects of ACh on the firing of medium spiny neurons. Nicotinic receptors with high- and low- affinity appear to play greater roles in reward enhancement and inhibition, respectively. Cholinergic inhibition of natural and drug rewards may serve as mediators of previously described opponent processes. Future studies should evaluate cholinergic agents across a broader range of doses, and include a variety of reinforced behaviors.

Greater participation of ethnically diverse participants in clinical trials for AD would generate additional information on possible differences in metabolism, treatment response, adverse events to therapeutic agents, and could foster the investigation of genetic variability among ethnic groups.

Alzheimer's disease (AD) is the most common neurodegenerative disorder and the most prevalent cause of dementia with ageing. Pharmacological treatment of AD is based on the use of acetylcholinesterase inhibitors, which have beneficial effects on cognitive, functional, and behavioural symptoms of the disease, but their role in AD pathogenesis is unknown. Other pharmacological therapies are becoming available--including the recently approved drug memantine, an NMDA channel blocker indicated for advanced AD. Here, we review clinical features of the available cholinesterase inhibitors (donepezil, rivastigmine, and galantamine) including their pharmacological properties, the evidence for switching from one agent to another, "head to head" studies, and the emerging evidence for the use of memantine in AD. New therapeutic approaches--including those more closely targeted to the pathogenesis of the disease--will also be reviewed. These potentially disease modifying treatments include amyloid-beta-peptide vaccination, secretase inhibitors, cholesterol-lowering drugs, metal chelators, and anti-inflammatory agents.

Two hundred seventy patients with a mean age of 78.5 (SD = 7.56) years and a mean duration of dementia of 3.5 (SD = 2.06) years were included in the study. Sixty-nine percent of patients completed the study with 17.8% discontinuing due to adverse events. Eighty-three percent of patients reported at least 1 adverse event, with the most frequently occurring adverse events affecting the gastrointestinal system (54%). The majority of patients were reported to have either improvement or no decline on the CGIC. A limitation of the study is that the interpretation of the results is based on an overall completion rate of 69%.

Four drugs are licensed in the UK for the management of Alzheimer's disease. These are the cholinesterase inhibitors donepezil, rivastigmine and galantamine, and memantine, which decreases the action of the neurotransmitter glutamate. Cholinesterase inhibitors increase the availability of acetylcholine at the synaptic cleft between neurones by preventing its breakdown by the enzyme acetylcholinesterase. The four drugs are only licensed for Alzheimer's disease, with rivastigmine also licensed for Parkinson's disease. For vascular dementia they have been shown to give modest improvements in cognitive function but not for activities of living and so are not recommended.

Galantamine, a centrally acting cholinesterase (ChE) inhibitor and a nicotinic allosteric potentiating ligand used to treat Alzheimer's disease, is an effective and safe antidote against poisoning with nerve agents, including soman. Here, the effectiveness of galantamine was compared with that of the centrally active ChE inhibitors donepezil, rivastigmine, and (+/-)huperzine A as a pre- and/or post-treatment to counteract the acute toxicity of soman. In the first set of experiments, male prepubertal guinea pigs were treated intramuscularly with one of the test drugs and 30 min later challenged with 1.5 x LD(50) soman (42 microg/kg s.c.). All animals that were pretreated with galantamine (6-8 mg/kg), 3 mg/kg donepezil, 6 mg/kg rivastigmine, or 0.3 mg/kg (+/-)huperzine A survived the soman challenge, provided that they were also post-treated with atropine (10 mg/kg i.m.). However, only galantamine was well tolerated. In subsequent experiments, the effectiveness of specific treatment regimens using 8 mg/kg galantamine, 3 mg/kg donepezil, 6 mg/kg rivastigmine, or 0.3 mg/kg (+/-)huperzine A was compared in guinea pigs challenged with soman. In the absence of atropine, only galantamine worked as an effective and safe pretreatment in animals challenged with 1.0 x LD(50) soman. Galantamine was also the only drug to afford significant protection when given to guinea pigs after 1.0 x LD(50) soman. Finally, all test drugs except galantamine reduced the survival of the animals when administered 1 or 3 h after the challenge with 0.6 or 0.7 x LD(50) soman. Thus, galantamine emerges as a superior antidotal therapy against the toxicity of soman.

The last decade was very fruitful in neuropharmacology and notably in the therapeutic strategies of dementia and Alzheimer's disease (AD). The amount of data, information and breakthroughs is nevertheless difficult to apply in direct relationship with patients. The present review aims at classifying information according to their origins: epidemiology, clinical trials, neurosciences. A guide for drug prescription in Alzheimer's disease is thus warranted and becomes clearer, sure that, in the next future modifications and new strategies will appear. The main goal of the present review is to summarize the state-of-the-art for a non specialist in AD.

Switching patients with Alzheimer's disease from one cholinesterase inhibitor to another represents a viable option for patients not responding to current therapy. The objective of this large U.S.-based study was to evaluate the safety and efficacy of a treatment switch to rivastigmine in patients not responding adequately to or declining on treatment with donepezil.

Ten studies (n = 338 patients) were included. Four trials addressed interventions for excessive daytime sleepiness. Meta-analysis of the three trials evaluating modafinil showed a significant reduction in sleepiness, as assessed by the Epworth Sleepiness Scale (ESS) (- 2.24 points, 95% CI - 3.90 to - 0.57, p < 0.05). In one study, treatment with caffeine was associated with a non-significant improvement of 1.71 points in ESS (95% CI, - 3.57 to 0.13). The six remaining trials assessed interventions for insomnia and REM sleep Behaviour Disorder (RBD). Single study results suggest that doxepin and YXQN granules might be efficacious, while pergolide may be deleterious for insomnia and that rivastigmine may be used to treat RBD in PD patients. However, there is insufficient evidence to support or refute the efficacy of any of these interventions. No relevant side effects were reported.

Alzheimer's disease (AD) is characterized in the brain by the deposition of amyloid protein outside the neuron, resulting in the formation of plaques, and inside the neuron with neurofibrillary tangles. It is not yet known what causes these pathologic changes, although age and genetics are major risk factors. The cholinesterase inhibitors tacrine and donepezil block acetylcholinesterase and therefore preserve the neurotransmitter acetylcholine. Three other investigational cholinesterase inhibitors are rivastigmine, metrifonate, and galanthamine. Existing therapies being studied for use in AD include vitamin E, estrogen preparations, and anti-inflammatory agents. The physician's role is to care for both the AD patient and the family, which are profoundly affected by this disease.

In a multicenter, nonblinded, randomized controlled trial, 264 volunteers with AD were randomly divided into 4 groups of 66; groups 1, 2, 3 and 4 received donepezil, rivastigmine, MLC601 and galantamine, respectively. Subjects underwent a clinical diagnostic interview and a cognitive/functional battery including the Mini-Mental State Examination (MMSE) and Alzheimer's Disease Assessment Scale - Cognitive subscale (ADAS-Cog). Patients were visited every 4 months, and the score of cognition was recorded by the neurologists.

Donepezil is a potent acetylcholinesterase inhibitor used for the treatment of Alzheimer's disease. Although acetylcholinesterase inhibitors are thought to be symptomatic treatment of Alzheimer's disease, it is not clear whether they are effective against progressive degeneration of neuronal cells. In this study, we investigated the neuroprotective effects of donepezil against ischemic damage, N-methyl-d-aspartate (NMDA) excitotoxicity, and amyloid-beta (Abeta) toxicity using rat brain primary cultured neurons. Lactate dehydrogenase (LDH) released into the culture medium was measured as a marker of neuronal cell damage. As an ischemic damage model, we used oxygen-glucose deprivation in rat cerebral cortex primary cultured neurons. Pretreatment with donepezil (0.1, 1 and 10 microM) significantly decreased LDH release in a concentration-dependent manner. However, other acetylcholinesterase inhibitors (galantamine, tacrine and rivastigmine) did not significantly decrease LDH release. In a NMDA excitotoxicity model, pretreatment with donepezil (0.1, 1 and 10 microM) decreased the LDH release in a concentration buy exelon -dependent manner. In binding assay for glutamate receptors, donepezil at 100 microM only slightly inhibited binding to the glycine and polyamine sites on NMDA receptor complex. We further examined the effect of donepezil on Abeta (1-40)- and Abeta (1-42)-induced toxicity in primary cultures of rat septal neurons. Pretreatment with donepezil (0.1, 1 and 10 microM) significantly decreased LDH release induced by Abetas in a concentration-dependent manner. However, other acetylcholinesterase inhibitors (galantamine and tacrine) and NMDA receptor antagonists (memantine and dizocilpine (MK801)) did not significantly decrease LDH release. These results demonstrate that donepezil has protective effects against ischemic damage, glutamate excitotoxicity and Abeta toxicity to rat primary cultured neurons and these effects are not dependent on acetylcholinesterase inhibition and antagonism of NMDA receptors. Thus, donepezil is expected to have a protective effect against progressive degeneration of brain neuronal cells in ischemic cerebrovascular disease and Alzheimer's disease.

A rapid and sensitive buy exelon liquid chromatography-tandem mass spectrometry (LC-MS/MS) method has been developed and validated for the estimation of rivastigmine in human plasma. Rivastigmine was extracted from human plasma by using solid-phase extraction technique. Zolpidem was used as the internal standard. A Betabasic-8 column provided chromatographic separation of analytes followed by detection with mass spectrometry. The mass transition ion-pair was followed as m/z 251.20-->206.10, 86.20 for rivastigmine and m/z 308.10-->235.10 for zolpidem. The method involves a rapid solid-phase extraction from plasma, simple isocratic chromatographic conditions and mass spectrometric detection that enables detection at sub-nanogram levels. The proposed method has been validated for a linear range of 0.2-20.0 ng/ml with a correlation coefficient > or =0.9988. The intra-run and inter-run precision and accuracy were within 10.0%. The overall recoveries for rivastigmine and zolpidem were 86.28% and 87.57%, respectively. The total run time was 2.0 min. The developed method was applied for the determination of the pharmacokinetic parameters of rivastigmine following a single oral administration of a 3 mg rivastigmine capsule in 20 healthy male volunteers.

Most cost-effectiveness studies using simulation modeling have demonstrated that donepezil, rivastigmine, and galantamine are cost effective for the treatment of mild-to-moderate Alzheimer disease (AD). These conclusions are in large part based on the assumption that improvement in cognitive status, or prevention of cognitive and functional decline, reduces the amount of time patients spend institutionalized or receiving other full-time care. However, as discussed in this article, outcomes besides delay to institutionalization affect the costs of AD. In reviews of utilization data from Medicare and managed care organizations, it was noted that hospitalization and post acute care in skilled nursing facilities accounted for the largest amount of excess direct costs, even among patients with mild or moderate AD. These utilization reviews also suggest that many patients with AD and related dementias require inpatient care because they are not able to self-manage comorbid conditions. The improvements in cognitive status and daily functioning associated with acetylcholinesterase inhibitor (AChEI) therapy are expected to translate into improved management of comorbidities and reduced caregiver burden, thus reducing the total cost of care. To confirm these and other economic benefits of AChEIs, pharmacoeconomic outcomes should be evaluated routinely as part of randomized, controlled trials and through well-controlled observational studies buy exelon of AD patients in community and institutional settings.

An isocratic, reversed-phase liquid chromatographic (RPLC) method was developed for the quantitative determination of Rivastigmine hydrogen tartrate, a cholinesterase inhibitor in bulk drugs and in pharmaceutical dosage forms. The developed method is also applicable for the related substance determination of Rivastigmine hydrogen tartrate in bulk drugs. The chromatographic separation was achieved on a Waters X Terra RP18 (250 mm x 4.6 mm, 5 microm) column using aqueous 0.01 M sodium-1-heptane sulphonate (pH: 3.0 with dilute phosphoric acid)-acetonitrile (72:28, v/v) as a mobile phase. The chromatographic resolution between Rivastigmine and its potential impurity, namely (S)-3-(1-dimethylaminoethyl) phenol (Imp 1) was found to be greater than four. Forced degradation studies were performed for Rivastigmine hydrogen tartrate bulk drug using acid (0.5 N hydrochloric acid), base (0.5 N sodium hydroxide), oxidation (3% hydrogen peroxide), heat (60 degrees C) and UV light (254 nm). No degradation was observed for Rivastigmine hydrogen tartrate except in base hydrolysis and the formed degradation product was found to be Imp 1. The mass balance of Rivastigmine hydrogen tartrate was close to 100 in all the stress conditions. The limit of detection (LOD) and limit of quantification (LOQ) of Imp 1 were found to be 100 and 300 ng/ml, respectively, for 10 microl injection volume. The percentage recovery of Imp 1 in bulk drug sample was ranged from 95.2 to 104.3. The active pharmaceutical ingredient was extracted from its finished dosage form (capsule) using water. The percentage recovery of buy exelon Rivastigmine hydrogen tartrate was ranged from 99.2 to 101.3 and 98.6 to 101.5 in bulk and pharmaceutical formulation samples, respectively. Rivastigmine hydrogen tartrate sample solution and mobile phase were found to be stable for at least 48 h. The developed method was validated with respect to linearity, accuracy, precision, robustness and forced degradation studies prove the stability indicating power of the method.

Approximately 10-20% of the direct costs of Alzheimer's disease are attributed to pharmacological treatment. Less than 20% of Alzheimer's disease patients are moderate responders to conventional drugs (e.g., donepezil, rivastigmine, galantamine, memantine) with doubtful cost-effectiveness. In total, 15% of the Caucasian population with Alzheimer's disease are carriers of defective CYP2D6 polymorphic variants that are potentially responsible for therapeutic failures when receiving cholinesterase inhibitors and psychotropic drugs. In addition, structural genomics studies demonstrate that > 100 genes might be involved in Alzheimer's disease pathogenesis, regulating dysfunctional genetic networks leading to premature neuronal death. The Alzheimer's disease population exhibits a higher genetic variation buy exelon rate than the control population, with absolute and relative genetic variations of 40-60% and 0.85-1.89%, respectively. Alzheimer's disease patients also differ from patients with other forms of dementia in their genomic architecture, possibly with different genes acting synergistically to influence the phenotypic expression of biological traits. Functional genomics studies in Alzheimer's disease reveal that age of onset, brain atrophy, cerebrovascular haemodynamics, brain bioelectrical activity, cognitive decline, apoptosis, immune function and amyloid deposition are associated with Alzheimer's disease-related genes. Pioneering pharmacogenomics studies also demonstrate that the therapeutic response in Alzheimer's disease is genotype-specific, with APOE-4/4 carriers as the worst responders to conventional treatments. It is likely that pharmacogenetic and pharmacogenomic factors account for 60-90% of drug variability in drug disposition and pharmacodynamics. The incorporation of pharmacogenomic/pharmacogenetic protocols in Alzheimer's disease may foster therapeutic optimisation by helping to develop cost-effective drugs, improving efficacy and safety, and reducing adverse events and cutting-down unnecessary cost for the industry and the community.

The development of selective reactions that utilize easily available and abundant precursors for the efficient synthesis of amines is a long-standing goal of chemical research. Despite the centrality of amines in a number of important research areas, including medicinal chemistry, total synthesis and materials science, a general, selective and step-efficient synthesis of amines is still needed. Here, we describe a set of mild catalytic conditions utilizing a single copper-based catalyst that enables the direct preparation of three distinct and important amine classes (enamines, α-chiral branched alkylamines and linear alkylamines) from readily available alkyne starting materials with high levels of chemo-, regio- and stereoselectivity. This methodology was applied to the asymmetric synthesis of rivastigmine and the formal synthesis of several other pharmaceutical agents, including Valtrex Brand Name duloxetine, atomoxetine, fluoxetine and tolterodine.

Consistent with the improvement in clinical outcomes, there was an observed increase in quality-adjusted survival time in the Luvox 100 Mg rivastigmine arm of 2.81 quality-adjusted life-days (two-sided p-value 0.13 [90% CI -0.243, 5.86]). Using Canadian price weights, there was an observed increase in cost in the rivastigmine arm of Can 55.76 dollars(two-sided p-value 0.98 [90% CI -3431, 3543]), with a resulting incremental cost-effectiveness ratio of Can 7429 dollars per QALY. Using UK price weights, there was an observed decrease in cost in the rivastigmine arm of pound 26.18 (two-sided p-value 0.99 [90% CI -2407, 2355]).

Rivastigmine has beneficial effects on cognitive functioning in Alzheimer's disease (AD). Effects of cholinesterase inhibitors, particularly rivastigmine, on AD Assessment Scale-cognitive subscale (ADAS-cog) domains and individual items have rarely been analyzed. Results from 4 randomized, double-blind, placebo-controlled, 26-week rivastigmine capsule trials in patients with mild-to-moderate AD were pooled and ADAS-cog domains and individual items were evaluated. Data were available from 878, 1053, and 863 patients in the 1 to 4 mg/d, 6 to 12 mg/d, and placebo groups, respectively. Rivastigmine-treated groups were superior to placebo on total ADAS-cog and memory domain scores (P < or = .0001). Rivastigmine 6 to 12 mg/d was also significantly better versus placebo on language (P < .001) and praxis (P < .001); greatest treatment responses were seen on memory items (P < .0001). Although rivastigmine was associated with dose-dependent improvements in all cognitive domains, largest effects were on memory items. Evaluation of Norvasc And Alcohol ADAS-cog domain scores provides insight into test items most likely to respond to treatment.
