Unlike other N-methyl-D-aspartate receptor (NMDAR) antagonists, clinical trials have shown that memantine is clinically tolerated and effective in the treatment of Alzheimer's disease. The mechanism for memantine tolerability, however, remains contentious but may be partly explained by its uncompetitive antagonism. The specific site of memantine block in the NMDAR channel interacts with magnesi...
BACKGROUND Memantine is effective in the treatment of behavioral disturbances in patients with Alzheimer's disease. It has not yet been fully determined which behavioral disturbances respond best to memantine. METHODS We conducted a meta-analysis of memantine vs control (placebo or usual care) for the treatment of individual behavioral disturbances (delusion, hallucination, agitation/aggressi...
BACKGROUND Memantine has been used off-label to treat frontotemporal lobar degeneration (FTD). A previous 26-week open-label study suggested a transient, modest benefit on neuropsychiatric symptoms as measured by the neuropsychiatric inventory (NPI). We aimed to determine whether memantine is an effective treatment for FTD. METHODS We did a randomised, parallel group, double-blind, placebo-co...
Delayed cerebral vasospasm is an important pathological feature of subarachnoid hemorrhage (SAH). The cause of vasospasm is multifactorial. Impairs nitric oxide availability and endothelial nitric oxide synthase (eNOS) dysfunction has been reported to underlie vasospasm. Memantine, a low-affinity uncompetitive N-methyl-d-aspartate (NMDA) blocker has been proven to reduce early brain injury afte...
introduction: in this study, the effect of memantine administration into the nucleus accumbens on the metabolic changes induced by acute stress in female mice was evaluated. methods: intra-accumbens unilateral or bilateral canulation was performed. one week after recovery, a group of animals were given memantine (1, 0.5, and 0.1 μg/mouse) five min before stress induction intra-accumbally, and t...
Introduction: Ischemic stroke is amongst the top four causes of mortality and the leading cause of disability in the world. The aim of this study was to evaluate the efficacy of a high dose memantine on neurological function of patients with ischemic stroke.Methods: In a randomized, 2 armed, open-label study, patients with mild to moderate cerebral thromboembolic event (CTEE) who admitted to Im...
Background and purpose: Memantine is a medication used to treat moderate to severe Alzheimer’s disease. Memantine targeting the glutamatergic system specifically N-Methyl-D-Aspartate offer a novel approach in treatment of psychiatric disorders such as schizophrenia and schizoaffective disorder. The purpose of this study was to evaluate the efficacy and safety of memantine in combination with an...
OBJECTIVE To investigate the effects of memantine, an N-methyl-d-aspartate (NMDA) receptor antagonist, on cognitive impairments in patients with chronic schizophrenia. METHODS A 12-week, placebo-controlled trial was conducted to determine the effectiveness of memantine as an adjunctive treatment with conventional antipsychotic medications in 26 patients with chronic schizophrenia. The subject...
BACKGROUND/AIMS In a post-marketing observational study, the efficacy and tolerability of memantine were examined in patients with moderate to severe Alzheimer's disease. METHODS The patients were treated with 20 mg/day of memantine for a 6-month period. The efficacy of memantine was evaluated using the Mini-Mental State Examination, the Nurses' Observation Scale for Geriatric Patients (NOSGE...
Preformulation studies regarding a physico-chemical evaluation of memantine, a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist, are presented in this work. This characterization of memantine is pre-required for the formulation of a parenteral solution. The water solubility, the thermal behavior and the chemical stability in aqueous solution, depending on the pH, temperature, UV ...
