Insights

Ondansetron did not improve cognitive decline in Alzheimer disease patients. The drug was safe and well-tolerated, but showed no significant cognitive benefits in this clinical trial.

Area of Science:

  • Neuroscience
  • Clinical Pharmacology
  • Geriatric Medicine

Background:

  • Alzheimer disease is a progressive neurodegenerative disorder characterized by cognitive decline.
  • Current treatments offer limited efficacy in halting or reversing cognitive impairment.
  • Investigating novel therapeutic agents for Alzheimer disease is crucial.

Purpose of the Study:

  • To evaluate the efficacy and safety of ondansetron in patients with Alzheimer disease.
  • To determine if ondansetron can mitigate or reverse cognitive decline associated with Alzheimer disease.

Main Methods:

  • A multicenter, double-blind, placebo-controlled clinical trial was conducted.
  • 185 patients with Alzheimer disease were enrolled.
  • Participants received either ondansetron (20 microg/day or 100 microg/day) or a placebo.

Main Results:

  • Ondansetron was well-tolerated by patients.
  • No serious drug-related side effects were observed.
  • The study did not demonstrate significant cognitive improvement in patients treated with ondansetron compared to placebo.

Conclusions:

  • Ondansetron is a safe and well-tolerated medication for Alzheimer disease patients.
  • Ondansetron at the tested dosages does not appear to be effective in treating cognitive decline in Alzheimer disease.

Alzheimer's Disease: Treatment

Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...

Parkinson's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of its...

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function. They...
