A pharmacokinetic study of intravenously and orally administered memantine was run on 12 pigs. The blood samples were collected up to 12 hours after drug administration. The memantine plasma levels were determined using a validated method of liquid chromatography coupled with mass spectrometry detection. Six pharmacokinetic models were screened and the best one describing the absorption and dis...
Alzheimer's disease (AD) is the most common cause of dementia, accounting for 25 million cases worldwide. Until recently, the pharmacotherapy of AD was limited to the use of cholinesterase inhibitors (ChEIs) that are approved only for the mild to moderate stages of the illness. Memantine, an NMDA receptor antagonist has been found to be effective, both as monotherapy and in combination with don...
Role of glutamate and advantages of combining memantine with a 5HT6 ligand in a model of depression.
BACKGROUND It is a well-known fact that 5HT6 ligands increase glutamate levels. In the current study we investigated whether a 5HT6 antagonist, SB399885 would show antidepressant like property at a dose which would significantly increase the glutamate levels. Further we studied if the combination of a 5HT6 antagonist and N-methyl-D-aspartate (NMDA) antagonist, memantine would restore the antide...
BACKGROUND Previous cost-effectiveness studies of cholinesterase inhibitors have modeled Alzheimer's disease (AD) progression and treatment effects through single or global severity measures, or progression to "Full Time Care". This analysis evaluates the cost-effectiveness of donepezil versus memantine or no treatment in Germany by considering correlated changes in cognition, behavior and func...
PURPOSE To determine, using electrophysiological measures of visual system function, whether oral daily dosing of memantine is both safe and effective to reduce the injury associated with experimental glaucoma in primates. METHODS Argon laser treatment of the anterior chamber angle was used to induce chronic ocular hypertension (COHT) in the right eye of 18 macaque monkeys. Nine animals were ...
BACKGROUND AND OBJECTIVE Dextromethorphan/quinidine (DMQ) is the first agent indicated for the treatment of pseudobulbar affect. Dextromethorphan, the active ingredient, is a low-affinity, uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist. This study evaluated the potential for a drug-drug interaction (DDI) of DMQ with memantine, which is also an NMDA receptor antagonist. METHODS ...
IMPORTANCE Although vitamin E and memantine have been shown to have beneficial effects in moderately severe Alzheimer disease (AD), evidence is limited in mild to moderate AD. OBJECTIVE To determine if vitamin E (alpha tocopherol), memantine, or both slow progression of mild to moderate AD in patients taking an acetylcholinesterase inhibitor. DESIGN, SETTING, AND PARTICIPANTS Double-blind, ...
OBJECTIVES Recent studies have confirmed the contribution of the central nervous system (CNS) to the pathogenesis of Complex Regional Pain Syndrome (CRPS), because animal models of neuropathic pain syndromes demonstrate an overexpression of N-methyl-D-aspartate-receptors in the CNS. The aim of this work was to study the influence of a central acting drug-the N-methyl-D-aspartate receptor antago...
The present study evaluated the effects of once-daily memantine (20 mg) treatment on cognition and communication in patients with moderate to severe Alzheimer's disease (AD). In a multicenter, single-arm open-label study, outpatients diagnosed with AD (MMSE < 20; n = 97) were titrated from 5 mg to 20 mg once-daily memantine over 4 weeks. Once-daily memantine treatment (20 mg) was then continued...
N-(2-Indanyl)-glycinamide hydrochloride (CHF3381) is a novel low-affinity, noncompetitive N-methyl-d-aspartate receptor antagonist. The current study compared the antinociceptive effects of CHF3381 with those of gabapentin and memantine in in vitro and in vivo models of pain. In isolated rat spinal cord, CHF3381 and memantine, but not gabapentin, produced similar inhibition of the wind-up pheno...
