Insights

Cevimeline shows promise for Alzheimer's disease (AD) treatment by improving cognitive deficits in animal models and potentially reducing amyloid-beta and tau pathologies in patients. Further clinical studies are needed to confirm its efficacy for dementia.

Area of Science:

  • Neuroscience
  • Pharmacology
  • Gerontology

Background:

  • Alzheimer's disease (AD) and related dementias are currently incurable, necessitating novel therapeutic strategies.
  • Improving cognitive function, particularly memory loss, is a primary goal in managing early-stage dementia.
  • Targeting the neuromodulator acetylcholine via muscarinic receptors presents a potential therapeutic avenue.

Purpose of the Study:

  • To systematically review the potential of cevimeline in enhancing cognitive functions for patients with Alzheimer's disease.
  • To explore cevimeline's impact on key pathological markers associated with AD.

Main Methods:

  • A systematic literature review was conducted using major scientific databases: Web of Science, PubMed, Springer, and Scopus.
  • Studies investigating cevimeline's effects on cognitive function and AD pathology were analyzed.

Main Results:

  • Cevimeline demonstrated efficacy in improving experimentally induced cognitive deficits in animal models.
  • The drug showed a positive influence on tau pathology and reduced amyloid-beta (Aβ) peptide levels in cerebrospinal fluid of AD patients.

Conclusions:

  • Cevimeline exhibits potential as a therapeutic agent for Alzheimer's disease, impacting cognitive function and core pathologies.
  • Despite promising preclinical and preliminary findings, FDA approval is pending, and extensive clinical trials are required to validate its use in AD patients.

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.

Direct-Acting Cholinergic Agonists: Therapeutic Uses

Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren...

Drugs Affecting Neurotransmitter Release or Uptake01:21

Drugs Affecting Neurotransmitter Release or Uptake

Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

Direct-Acting Cholinergic Agonists: Pharmacological Actions00:59

Direct-Acting Cholinergic Agonists: Pharmacological Actions

Direct-acting cholinergic agonists exert their pharmacological actions by mimicking the effects of acetylcholine on postsynaptic muscarinic receptors to generate parasympathetic responses. These agents elicit a range of physiological responses, including cardiovascular effects. For example, activation of muscarinic receptors induces bradycardia, decreased cardiac output, reduced peripheral resistance, and consequent hypotension. In the eye, stimulation of M3 receptors leads to smooth muscle...

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...

Cholinergic Receptors: Muscarinic01:25

Cholinergic Receptors: Muscarinic

The pharmacological actions of acetylcholine are elicited via its binding to two families of cholinergic receptors or cholinoceptors, namely, muscarinic and nicotinic receptors. Muscarinic receptors are G protein-coupled receptors and have five subtypes, M1–M5. All mAChR subtypes are activated by acetylcholine and blocked by the antagonist, atropine. 
The subtypes M1, M3, and M5 couple with the Gq subunit and activate the phospholipase C (PLC) activity, mobilizing intracellular Ca2+....
