Rivastigmine
Rivastigmine, sold under the brand name Exelon among others, is an acetylcholinesterase inhibitor used for the treatment of dementia associated with Alzheimer's disease and with Parkinson's disease. Rivastigmine can be administered orally or via a transdermal patch; the latter form reduces the prevalence of side effects, which typically include nausea and vomiting. Rivastigmine is eliminated through the urine, and appears to have relatively few drug-drug interactions. It was patented in 1985 and came into medical use in 1997. Medical uses Rivastigmine is indicated for the treatment of dementia of the Alzheimer's type; and for the treatment of dementia associated with Parkinson's disease. Rivastigmine capsules, liquid solution and patches are used for the treatment of mild to moderate dementia of the Alzheimer's type, and for mild to moderate Parkinson's disease dementia. Rivastigmine has demonstrated treatment effects on the cognitive (thinking and memory), functional (act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cholinesterase Inhibitor
Cholinesterase inhibitors (ChEIs), also known as anti-cholinesterase, are chemicals that prevent the breakdown of the neurotransmitter acetylcholine or butyrylcholine by cholinesterase. This increases the amount of the acetylcholine or butyrylcholine in the Chemical synapse#Structure, synaptic cleft that can bind to Muscarinic acetylcholine receptor, muscarinic receptors, Nicotinic acetylcholine receptor, nicotinic receptors and others. This group of inhibitors is divided into two subgroups, acetylcholinesterase inhibitors (AChEIs) and Butyrylcholinesterase#Inhibitors, butyrylcholinesterase inhibitors (BChEIs). ChEIs may be used as drugs for Alzheimer's disease, Alzheimer's and myasthenia gravis, and also as chemical weapons and insecticides. Side effects when used as drugs may include Anorexia (symptom), loss of appetite, nausea, vomiting, Diarrhea#Definition, loose stools, Dream, vivid dreams at night, dehydration, rash, bradycardia, peptic ulcer disease, seizures, weight los ...

Marta Weinstock-Rosin
Marta Weinstock-Rosin (born 1935; Hebrew: מרתה וינשטוק-רוזין) is an Austrian-born Israeli neuropharmacologist, best known as the developer of rivastigmine (Exelon). Early life and education Weinstock-Rosin was born in Vienna. After her father was arrested for being Jewish, the family fled Austria for England in 1939, shortly before the war. Her early days in England were difficult. Her father was arrested as a citizen of an enemy state, and her mother had no skills and didn't speak English. Food was a challenge to find and much of her time was spent in air raid shelters. At age 12 she looked up the word "pharmacologist" in an encyclopedia and decided that research, drug development and chemistry would be her career. She had to fight the system to succeed. She had to go to a boys class to study physics, as it wasn't offered in her girls school; also, her father disapproved of her medical plans, as he was afraid she would never get married. She received a PharmD ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donepezil
Donepezil, sold under the brand name Aricept among others, is a medication used to treat dementia of the Alzheimer's type. It appears to result in a small benefit in mental function and ability to function. Use, however, has not been shown to change the progression of the disease. Treatment should be stopped if no benefit is seen. It is taken by mouth or via a transdermal patch. Donepezil is a centrally acting reversible acetylcholinesterase inhibitor and structurally unrelated to other anticholinesterase agents. Common side effects include nausea, trouble sleeping, aggression, diarrhea, feeling tired, and muscle cramps. Serious side effects may include abnormal heart rhythms, urinary incontinence, and seizures. Donepezil was approved for medical use in the United States in 1996. It is available as a generic medication. In 2022, it was the 146th most commonly prescribed medication in the United States, with more than 3million prescriptions. Medical uses Alzheimer's di ...

Antidementia Agents
Dementia is a syndrome associated with many neurodegenerative diseases, characterized by a general decline in cognitive abilities that affects a person's ability to perform activities of daily living, everyday activities. This typically involves problems with memory, thinking, behavior, and motor control. Aside from memory impairment and a thought disorder, disruption in thought patterns, the most common symptoms of dementia include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum (measurement), continuum over several stages. Dementia is a life-limiting condition, having a significant effect on the individual, their caregivers, and their social relationships in general. A diagnosis of dementia requires the observation of a change from a person's usual mental functioning and a greater cognitive decline than might be caused by the normal aging process. Several diseases and injuries to the brain, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acetylcholinesterase Inhibitors
Acetylcholinesterase inhibitors (AChEIs) also often called cholinesterase inhibitors, inhibit the enzyme acetylcholinesterase from Hydrolysis, breaking down the neurotransmitter acetylcholine into choline and acetate, thereby increasing both the level and duration of action of acetylcholine in the central nervous system, Autonomic ganglion, autonomic ganglia and neuromuscular junctions, which are rich in acetylcholine receptors. Acetylcholinesterase inhibitors are one of two types of cholinesterase inhibitors; the other being Butyrylcholinesterase#Inhibitors, butyryl-cholinesterase inhibitors. Acetylcholinesterase is the primary member of the cholinesterase, cholinesterase enzyme family. Acetylcholinesterase inhibitors are classified as reversible, irreversible, or quasi-irreversible (also called pseudo-irreversible). Mechanism of action Organophosphates Organophosphates like TEPP, tetraethyl pyrophosphate (TEPP) and sarin inhibit cholinesterases, enzymes that hydrolyze the ...

Physostigmine
Physostigmine (also known as eserine from ''éséré'', the West African name for the Calabar bean) is a highly toxic parasympathomimetic alkaloid, specifically, a reversible cholinesterase inhibitor. It occurs naturally in the Calabar bean and the fruit of the Manchineel tree. The chemical was synthesized for the first time in 1935 by Percy Lavon Julian and Josef Pikl. It is available in the U.S. under the trade names Antilirium and Isopto Eserine, and as eserine salicylate and eserine sulfate. Today, physostigmine is most commonly used for its medicinal value. However, before its discovery by Robert Christison, Sir Robert Christison in 1846, it was much more prevalent as an ordeal poison. The positive medical applications of the drug were first suggested in the gold medal-winning final thesis of Thomas Richard Fraser at the University of Edinburgh in 1862. Medical uses Physostigmine, an acetylcholinesterase inhibitor, can be used to treat glaucoma and delayed gastric emptyin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alzheimer's Disease
Alzheimer's disease (AD) is a neurodegenerative disease and the cause of 60–70% of cases of dementia. The most common early symptom is difficulty in remembering recent events. As the disease advances, symptoms can include problems with language, disorientation (including easily getting lost), mood swings, loss of motivation, self-neglect, and behavioral issues. As a person's condition declines, they often withdraw from family and society. Gradually, bodily functions are lost, ultimately leading to death. Although the speed of progression can vary, the average life expectancy following diagnosis is three to twelve years. The causes of Alzheimer's disease remain poorly understood. There are many environmental and genetic risk factors associated with its development. The strongest genetic risk factor is from an allele of apolipoprotein E. Other risk factors include a history of head injury, clinical depression, and high blood pressure. The progression of the di ...
