چکیده

Cholinesterase inhibitors (ChE-Is) are among the main drugs approved for the treatment of Alzheimer's disease (AD). Rivastigmine in the form of a transdermal patch is an alternative delivery method, and can give greater treatment compliance. Objectives To conduct a preliminary assessment of the neurocognitive and biological effects of oral and transdermal Rivastigmine in patients with AD and to identify a potential biological marker and demonstrate a possible relationship between esterase levels and behavioral scores of AD patients. Methods Forty patients with AD were treated with cholinesterase inhibitors (ChE-Is), evaluated using the MMSE and NPI, and simultaneously sampled to determine their serum levels of AChE and BuChE for 180 days. Results The differences obtained between oral and transdermal forms, as assessed by the MMSE and NPI scores of the AD patients, were not significant at the three time points examined (0, 90, and 180 days). However, serum BuChE levels of the transdermal group differed significantly (p<0.0004) compared with those of the oral group at 90 days. Conclusion Use of a transdermal ChE-I, rivastigmine tartrate significantly reduced BuChE levels in the AD patients studied.

Rivastigmine: the advantages of dual inhibition of acetylcholinesterase and butyrylcholinesterase and its role in subcortical vascular dementia and Parkinson’s disease dementia

Several studies have demonstrated clinical benefits of sustained cholinesterase inhibition with rivastigmine in Alzheimer's disease (AD) and Parkinson's disease dementia (PDD). Unlike donepezil and galantamine that selectively inhibit acetylcholinesterase (AChE; EC 3.1.1.7), rivastigmine is a unique cholinesterase inhibitor with both AChE and butyrylcholinesterase (BuChE; EC 3.1.1.8) inhibitory...

Prevalence of Wild-Type Butyrylcholinesterase Genotype in Patients with Alzheimer’s Dementia

Approximately, two-thirds patients with Alzheimer’s disease (AD) are reported to have homozygous wild-type butyrylcholinesterase (BuChE) gene expression. It is associated with a higher rate of hydrolysis of acetylcholine, which ultimately leads to increase in the levels of BuChE in advanced stages of the disease. Rivastigmine, a dual inhibitor of acetylcholinesterase (AChE) and BuChE, might be ...
