Donepezil is a centrally acting reversible acetylcholinesterase inhibitor and structurally unrelated to other anticholinesterase agents. [8] [5] Common side effects include nausea, trouble sleeping, aggression, diarrhea, feeling tired, and muscle cramps. [8] [11] Serious side effects may include abnormal heart rhythms, urinary incontinence, and ...
Donepezil: Donepezil may exhibit cardiac issues such as hypertension, cardiac arrhythmia, atrioventricular block, and bradycardia due to its vagotonia properties. [2] Common gastrointestinal side effects such as nausea, diarrhea, and vomiting are also associated with donepezil and other acetylcholinesterase inhibitors. [ 2 ]
British physiologist Sir Henry Hallett Dale (1875-1968) observed acetylcholine for causing blood vessel dilation and slowing down heart rate. In 1914, Dale noted that the physiological effect of acetylcholine resembled the stimulation of parasympathetic nervous system and hypothesized acetylcholine as the neurotransmitter.
Anticholinergics generally have antisialagogue effects (decreasing saliva production), and most produce some level of sedation, both being advantageous in surgical procedures. [ 8 ] [ 9 ] Until the beginning of the 20th century, anticholinergic drugs were widely used to treat psychiatric disorders.
Acetylcholine Acetylcholinesterase Acetylcholinesterase inhibition. Acetylcholinesterase inhibitors (AChEIs) also often called cholinesterase inhibitors, [1] inhibit the enzyme acetylcholinesterase from breaking down the neurotransmitter acetylcholine into choline and acetate, [2] thereby increasing both the level and duration of action of acetylcholine in the central nervous system, autonomic ...
Neuropharmacology is the study of how drugs affect function in ... vessels and the increase in heart rate and blood ... such as Donepezil and ...
Some drugs and medications affect heart rate, meaning you may have a lower maximum heart rate and target zone, says Dr. Steinbaum. “If you have a heart condition or take medication, ask your ...
Paraoxon and rivastigmine are both acetylcholinesterase inhibitors and butyrylcholinesterase inhibitors. [14] [11] [7]In 2015, the United States Food and Drug Administration's Adverse Event Reporting System database compared rivastigmine to the other ChEI drugs donepezil and galantamine found that rivastigmine was associated with a higher frequency of reports of death as an adverse event.
