objective: in the present study, we examined the effects of memantine administration within the nucleus accumbens on the alterations in brain and adrenal volumes and weight ratios induced by stress from electric foot shock. methods: a group of mice received various doses of memantine (0.1, 0.5 and 1 mg/kg) prior to induction of stress. another group underwent intra-accumbal cannulation after an...

objective(s):breast cancer is an important leading cause of death from cancer. stathmin and tau proteins are regulators of cell motility, and their overexpression is associated with the progression and bad prognosis of breast cancer. memantine, an n-methyl-d-aspartate (nmda) receptor antagonist, is the potential inhibitor of tau protein in neurons. this study determines the effect of memantine ...

OBJECTIVE To determine whether treatment with memantine plus vitamin D is more effective than memantine or vitamin D alone in improving cognition among patients with Alzheimer disease (AD). METHODS We studied 43 white outpatients (mean 84.7 ± 6.3 years; 65.1% women) with a new diagnosis of AD, who had not taken anti-dementia drugs or vitamin D supplements. We prescribed memantine alone (n = 1...

Although memantine blocks sodium currents and produces local skin anesthesia, spinal anesthesia with memantine is unknown. The purpose of the study was to evaluate the local anesthetic effect of memantine in spinal anesthesia and its comparison with a widely used local anesthetic lidocaine. After intrathecally injecting the rats with five doses of each drug, the dose-response curves of memantin...

Aim: The aim of this study is to evaluate the effect of memantine on negative symptoms in patients with schizophrenia and schizoaffective. Methods: This is a double- blind randomized clinical trial. 58 patients participated in the study, 29 patients were randomly assigned to the memantine group and 29 patients to the placebo group. For assessing negative signs, and we used scale for the assess...

Objective. Glutamate, an excitatory neurotransmitter in the central nervous system (CNS), may play a role in the development of anxiety. Memantine partially blocks N-methyl-D-aspartate (NMDA) receptors' glutamate channels located in the CNS. This paper evaluates memantine as an augmentation therapy for treatment of anxiety. Methods. 15 consecutive partially responding anxious patients were trea...

Introduction: Memantine as N-Methyl-D-aspartic acid (NMDA) receptor antagonist is used in some neurological disorders. It has been reported that memantine has modulatory effects on the somatosensory information processing in healthy subjects. This study investigated the effect of memantine on electrophysiological properties of barrel cortex neurons in male rats. Methods: Single unit recording ...

Ketamine is an NMDA receptor (NMDAR) antagonist that elicits rapid antidepressant responses in patients with treatment-resistant depression. However, ketamine can also produce psychotomimetic effects that limit its utility as an antidepressant, raising the question of whether the clinically tolerated NMDAR antagonist memantine possesses antidepressant properties. Despite its similar potency to ...
