PATIENT INSTRUCTIONS FOR NAMENDA/MEMANTINE You have been started on a new medication, called Memantine. This medication is available as immediate release (IR) tablets or extended release (ER) capsules. You will be started at the lowest dose that will then be increased as tolerated to the highest effective dose. IR/ImmediateRelease dosage frequencyis once or twice a day: • Initial dose is 5mg once a day week one; 5mg twice a day week 2; 10mg in the morning and 5 mg at night week 3; to the maximum dose 10mg twice a day. ER/Extended Release dosage frequencyis once a day: • Initial dose is 7mg daily week one; 14mg daily week two; 21mg week three; to maximum dose of 28mg per day This medicine is most oftenprescribed for patients with moderate to severe memory loss fromAlzheimer's disease, Lewy body disease or vascular dementia. It may be started in addition to another medication you may be taking like Donepezil, Rivastigmine or Galantamine. How does thismedication work?. This medication helps many patients with moderate or severe dementia, inattention, or irritation; and to engage with others. Some patients may also show an improvement in agitation. Note: This medication does not improve memory Possible Side Effects? Usually this medication is well tolerated by the majority of patients. However, like all medications, there are potential side effects. • The most common are drowsiness and confusion. These side effectssometimes resolve with time and are usually dose related. So many patients do not experience these side effectson a lower dose. • Other side effectsmay include (usually much less than 10%) dizziness, headache and constipation. Call with any questions or concerns. Patient Follow-Up 2 - 3 month follow-up visit with your VA provider. .

In addition, growing evidence points to the existence of molecular mechanisms that keep alcohol consumption in check and that confer resilience for the development of AUD which we define herein as the STOP signaling pathways. In this review, we focus on examples of the GO and the STOP intracellular signaling pathways and discuss our current knowledge of how manipulations of these pathways may be used for the treatment of AUD.

The Use of Psychedelic Drugs in the Treatment of Problematic Drug and Alcohol Use
Tripping up addiction: The use of psychedelic drugs in the treatment of problematic drug and alcohol use Short Title: Illicit drugs in the treatment of addiction Celia Morgan 1,3, Amy McAndrew1, Tobias Stevens1, David Nutt2, Will Lawn1,3 1. Psychopharmacology and Addiction Research Centre, University of Exeter, UK 2. Centre for Neuropsychopharmacology, Imperial College London, UK 3. Clinical Psychopharmacology Unit, University College London, UK Address Corrrespondence to: Celia Morgan Psychopharmacology and Addiction Research Centre Washington Singer Laboratory University of Exeter Perry Road, Exeter Devon UK EX4 4QG Key words: addiction, psychedelics, ketamine, ibogaine, ayahuasca, LSD , psilocybin, neurogenesis, 1 Highlights: Psilocybin may reduce alcohol and tobacco use in addicted samples. Ibogaine and ayahuasca have shown promise in the treatment of various addictions through observational studies. Ketamine has been used to treat alcohol dependence and reduces cocaine self- administration in the human laboratory. Randomised controlled trials are greatly needed to further test the efficacy of all of these compounds. Psychedelic drugs may have their therapeutic qualities due to anti-depressant effects, stimulating neuroplasticity and long-term psychological changes. 2 Abstract Psychedelic drugs have been used as treatments in indigenous cultures for thousands of years. Yet, due to their legal status, there has been limited scientific research into the therapeutic potential of these compounds for psychiatric disorders. In the absence of other effective treatments however, researchers have begun again to systematically investigate such compounds and there is now evidence pointing to the use of psychedelic drugs in the treatment of addiction. In this review we focus on human evidence for the effectiveness of preparations used by indigenous cultures in the Amazon (ayahausca) and Africa (ibogaine) and worldwide (psilocybin), and more recently synthetised drugs such as the serotonergic hallucinogen LSD and the dissociative anaesthetic ketamine.

Identification of Genes Regulated by Memantine and MK-801 in Adult Rat Brain by Cdna Microarray Analysis
Neuropsychopharmacology (2004) 29, 1070–1079 & 2004 Nature Publishing Group All rights reserved 0893-133X/04 $25.00 www.neuropsychopharmacology.org Identification of Genes Regulated by Memantine and MK-801 in Adult Rat Brain by cDNA Microarray Analysis ´ ´1 1 ,1 Marketa Marvanova , Merja Lakso and Garry Wong* 1AI Virtanen Institute for Molecular Sciences, Department of Neurobiology, Laboratory of Functional Genomics and Bioinformatics, University of Kuopio, Kuopio, Finland In this study, we monitored gene expression profiles using cDNA microarrays after an acute systemic administration of the high affinity N-methyl-D-aspartate (NMDA) uncompetitive antagonist MK-801 (1 mg/kg; 4 h), and the clinically used moderate affinity antagonist memantine (25 mg/kg; 4 h) in adult rat brains. From a microarray containing 1090 known genes, 13 genes were regulated by both treatments of which 12 were upregulated and one was downregulated. In addition, 28 and 34 genes were regulated (X1.5- or p0.67- fold change) by either memantine or MK-801, respectively. Genes commonly regulated by both treatments and not previously reported were confirmed by in situ hybridization (ISH) and include regenerating liver inhibitory factor-1 (RL/IF-1), GDP-dissociation inhibitor 1 2 þ þ þ (GDI-1), neural visinin Ca -binding protein 2 (NVP-2), neuromedin B receptor, and Na /K transporting ATPase 2b. ISH with memantine (5–50 mg/kg) revealed regulation of these genes in other cortical and hippocampal regions. RL/IF-1 induction occurred at 1 h and returned to basal levels by 8 h, consistent with the profile of an immediate early gene.

The tablets also contain the following inactive ingredients: microcrystalline cellulose, lactose monohydrate, colloidal silicon dioxide, talc and magnesium stearate. In addition the following inactive ingredients are also present as components of the film coat: hypromellose, triacetin, titanium dioxide, FD&C yellow #6 and FD&C blue #2 (5 mg tablets), iron oxide black (10 mg tablets). Namenda oral solution contains memantine hydrochloride in a strength equivalent to 2 mg of memantine hydrochloride in each mL. The oral solution also contains the following inactive ingredients: sorbitol solution (70%), methyl paraben, propylparaben, propylene glycol, glycerin, natural peppermint flavor #104, citric acid, sodium citrate, and purified water. CLINICAL PHARMACOLOGY Mechanism of Action and Pharmacodynamics Persistent activation of central nervous system N-methyl-D-aspartate (NMDA) receptors by the excitatory amino acid glutamate has been hypothesized to contribute to the symptomatology of Alzheimer’s disease. Memantine is postulated to exert its therapeutic effect through its action as a low to moderate affinity uncompetitive (open-channel) NMDA receptor antagonist which binds preferentially to the NMDA receptor-operated cation channels.

Date of revision: 2600 Alfred-Nobel July 8th, 2016 Suite 400 St-Laurent, QC H4S 0A9 Control No. 181785 2 NAME OF DRUG Pr Ebixa® Memantine Hydrochloride Tablets 10 mg THERAPEUTIC CLASSIFICATION N-methyl-D-aspartate (NMDA) receptor antagonist ACTION AND CLINICAL PHARMACOLOGY Persistent activation of the central nervous system N-methyl-D-aspartate (NMDA) receptors by the excitatory amino acid glutamate has been hypothesized to contribute to the symptomatology of Alzheimer’s disease. Memantine is postulated to exert its therapeutic effect through its action as a low to moderate affinity uncompetitive (open channel) NMDA receptor antagonist, which binds preferentially to the NMDA receptor-operated cation channels. It blocks the effects of pathologically elevated sustained levels of glutamate that may lead to neuronal dysfunction. There is no clinical evidence that memantine prevents or slows neurodegeneration or alters the course of the underlying dementing process in patients with Alzheimer’s disease. Memantine exhibits low to negligible affinity for other receptors (GABA, benzodiazepine, dopamine, adrenergic, noradrenergic, histamine and glycine) or voltage-dependent Ca2+, Na+ or K+ channels. In addition, it does not directly affect the acetylcholine receptor or cholinergic transmission, which have been implicated in the cholinomimetic side effects (e.g., increased gastric acid secretion, nausea and vomiting) seen with acetylcholinesterase inhibitors. Memantine showed antagonist effects at the 5HT3 receptor with a potency similar to that for the NMDA receptor. 3 In vitro studies have shown that memantine does not affect the reversible inhibition of acetylcholinesterase by donepezil or galantamine.
