Galantamine hydrobromide (GAL) is a reversible acetylcholinesterase inhibitor, with properties to increase the concentration of acetylcholine in several brain structures. The aim of this study is to determine the effect of new galantamine peptide esters: 3,4-dichlorophenyl-alanil-leucil-glycine-galantamine (GAL-LEU) and 3,4-dichlorophenyl-alanil-valil-glycine-galantamine (GAL-VAL), on locomotor...

Alzheimer’s disease (AD) is the common cause of dementia affecting the elderly people. Among the various therapeutic approaches, cholinesterase inhibitors (ChEIs) are the first group of compounds that have produced modest improvements in cognitive function of AD patients. Galantamine, one of the ChEIs, has been approved by the US FDA for the treatment of mild or moderate AD. The objective of th...

AIMS To elucidate the efficacy of galantamine on cognition and behavioral and psychological symptoms of dementia (BPSD) in outpatients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) who have switched from donepezil to galantamine. MATERIALS AND METHODS We performed an uninterrupted switch from donepezil to galantamine without a washout period or dose titration in 44 ambulat...

Diisopropylfluorophosphate exerts its toxic effect by irreversibly inhibiting acetylcholinesterase. This results in over-stimulation of central and peripheral cholinergic activity. The aim of the present study was to evaluate the possible preventive effects of acute treatment with reversible acetylcholinesterase inhibitor galantamine against the signs of cholinergic toxic syndrome provoked by d...

INTRODUCTION Gln-1062 (Memogain) is a pharmacologically inactive prodrug of galantamine. Owing to its lipophilic nature, it preferentially enters the brain, where it is cleaved into active galantamine. Gln-1062 is expected to have fewer peripheral side effects than other cholinesterase inhibitors, with improved effectiveness. METHODS This was a double-blind, comparator and placebo-controlled,...

This review was conducted in order to determine the efficacy of donepezil and galantamine in the treatment of cognitive symptoms of Alzheimer's disease, and also to determine whether galantamine was a superior pharmacological intervention. Meta-analytic methods were used to analyse the data from eight empirical studies which met the inclusion criteria specified. By finding the mean effect sizes...

Galantamine is a natural product belonging to the isoquinoline alkaloid family of compounds. It was first discovered and isolated in the 1950s from Galanthus nivalis (common snowdrop) and Galanthus woronowii (Caucasian snowdrop), members of the Amaryllidaceae family (Marco and do Carmo Carreiras, 2006). Alzheimer’s disease (AD) is named after Dr. Alois Alzheimer, who first identified the diseas...

In this study, the patch-clamp technique was used to determine the effects of galantamine, a cholinesterase inhibitor and a nicotinic allosteric potentiating ligand (APL) used for treatment of Alzheimer's disease, on synaptic transmission in brain slices. In rat hippocampal and human cerebral cortical slices, 1 microM galantamine, acting as a nicotinic APL, increased gamma-aminobutyric acid (GA...

Pharmacologic treatments for Alzheimer's disease include the cholinesterase inhibitors donepezil, galantamine, and rivastigmine. We reviewed their evidence by searching MEDLINE, Embase, The Cochrane Library, and the International Pharmaceutical Abstracts from 1980 through 2007 (July) for placebo-controlled and comparative trials assessing cognition, function, behavior, global change, and safety...

BACKGROUND/AIMS The purpose of this systematic review was to compare the safety and tolerability of the cholinesterase inhibitors (ChEIs) donepezil, rivastigmine and galantamine for treating mild to moderate Alzheimer's disease (AD) patients in routine clinical practice. METHODS Electronic databases (Cochrane Library, Medline, EMBASE; accessed October 2008) and manual bibliographic searches w...
