Cardarelli, Napoli, Italy. This paper has reviewed evidence from clinical trials of the effectiveness of memantine, donepezil, or the two drugs in association in managing moderate-severe AD.
Double-blind, placebo-controlled randomized aricept RCTs using memantine or donepezil alone or in association versus placebo in moderate-severe Continue reading were reviewed. Analysis done in January considered the years — No evidence was found of advantages of the association of memantine-donepezil.
The heterogeneity of conditions explored by RCTs, the relatively short time of observation 24—52 weeksand namenda different cognitive assessment tools used namenda not allow comparing properly different trials. Alzheimer's disease ADthe most common adult-onset dementia, is associated with very high costs for families and the society, as these patients need support and often institutionalization in the advanced stage [ 1 ].
Treatment, even if it cannot delay the disease progression, has a symptomatic effect on some cognitive, psychological, and behavioral symptoms. The targets of drugs with regulatory indication for symptomatic namenda of AD are the cholinergic system and click glutamatergic systems.
Memantine is a moderate affinity, uncompetitive antagonist of NDMA receptors. It alleviates to some extent the behavioral symptoms of Alzheimer's disease, with benefits on cognitive, functional, and global status [ 3 ].
Memantine activity is explained by the diffusion of NMDA receptors which aricept more abundant in the hippocampus and in the cerebral aricept namenda, the brain areas more largely involved in cognition, learning, and memory.
Namenda or glutamic acid mediates long-term potentiation via NMDA receptors.
Elevated glutamate levels are associated with the aricept namenda of neurotoxicity phenomena and this could explain the beneficial effect of memantine in the blocking of the negative consequences of elevated glutamate levels. Memantine aricept or namenda 7 mg well tolerated; adverse effects are aricept or namenda 7 mg and no more frequent than placebo.
They include dizziness, confusion, somnolence, hallucinations, and nausea which disappear after discontinuation or dose reduction [ 67 ]. Slowing down of the acetylcholine catabolism makes aricept namenda more available.
All have demonstrated a small but measurable aricept benefit [ 910 ]. The use of aricept namenda association of donepezil with memantine for moderate-severe AD is more recent [ aricept or namenda 7 mg ]. Some studies reported that it may be effective to slow down the cognitive and functional decline, reducing therefore the nursing home admissions beyond what is found with single drugs [ 15 ].
The aim of this paper was to review clinical trials using memantine, donepezil, or the two drugs in association in managing moderate-severe AD.
In particular we wanted to answer to the following questions.
Analysis included and compared double-blind, placebo-controlled, randomized controlled trials RCTs evaluating memantine in monotherapy, donepezil in monotherapy, and the association of memantine plus donepezil in managing aricept namenda symptoms of patients with moderate-severe AD.
Our first aim namenda to clarify if the association aricept or namenda 7 mg two drugs might be more beneficial than single treatment.
Medically reviewed on November 10, Patients stabilized on memantine 10 mg twice a day or 28 mg ER once a day and donepezil 10 mg once a day: This drug should be initiated the day following the last dose of memantine and donepezil administered separately.
