What are some examples of cholinesterase?
List of examples of brand and generic names of cholinesterase inhibitors
- donepezil (Aricept, Aricept ODT)
- tacrine (Cognex) (This medication is discontinued in the US)
- rivastigmine (Exelon, Exelon Patch)
- galantamine (Razadyne or formerly Reminyl)
- memantine/donepezil (Namzaric)

What type of enzyme is cholinesterase?
Cholinesterase is a family of enzymes that catalyzes the hydrolysis of the neurotransmitter acetylcholine (ACh) into choline and acetic acid, a reaction necessary to allow a cholinergic neuron to return to its resting state after activation.
What is the difference between plasma cholinesterase and pseudocholinesterase?
Plasma cholinesterase (also known as pseudocholinesterase, butyrylcholinesterase, or BuChE) is a serine hydrolase that catalyses the hydrolysis of esters of choline.
What Are The cholinesterase drugs?
The three main cholinesterase inhibitors prescribed for Alzheimer’s disease are Aricept (donepezil), Razadyne ER (galantamine), and Exelon (rivastigmine). Depending on the severity of the disease, clinicians may add Namenda (memantine) to the treatment regimen.
What is serum cholinesterase?
Serum cholinesterase is a blood test that looks at levels of 2 substances that help the nervous system work properly. They are called acetylcholinesterase and pseudocholinesterase. Your nerves need these substances to send signals. Acetylcholinesterase is found in nerve tissue and red blood cells.
Is cholinesterase same as cholinergic?
Cholinomimetic drugs= Cholinergic agonists + Cholinesterase inhibitors. The cholinesterase inhibitors increase the activity of cholinergic neurons by blocking the enzyme acetylcholinesterase which metabolizes or breaks down acetylcholine. As such, cholinesterase inhibitors block the metabolism of acetylcholine.
What is the difference between acetylcholinesterase and cholinesterase?
The difference between the two types of cholinesterase is their relative preferences for substrates: AChE hydrolyzes acetylcholine faster while BChE hydrolyzes butyrylcholine faster.
What is atypical plasma cholinesterase?
Atypical Plasma Cholinesterase Two commonly used drugs—succinylcholine, a short-acting, depolarizing muscle relaxant used during intubation in general anesthesia, and the ester local anesthetics, such as procaine, chloroprocaine, tetracaine, and propoxycaine—are metabolized by the enzyme plasma cholinesterase.
What is pseudocholinesterase?
Pseudocholinesterase (soo-doe-koh-lin-ES-tur-ays) deficiency is a rare disorder that makes you sensitive to certain muscle relaxants ― succinylcholine or mivacurium ― used during general anesthesia.
Is atropine a cholinesterase inhibitor?
Atropine competitively inhibits the effects of cholinesterase inhibitors at muscarinic, but not nicotinic cholinergic receptors.
Is chlorpromazine a cholinesterase?
Drugs that inhibit cholinesterases….Cholinesterase Inhibitors.
| Drug | Drug Description |
|---|---|
| Chlorpromazine | A phenothiazine antipsychotic used to treat nausea, vomiting, preoperative anxiety, schizophrenia, bipolar disorder, and severe behavioral problems in children. |
| Cinchocaine | An anesthetic used for local or regional anesthesia. |
What is the difference between cholinergic and anticholinergic?
A. Cholinergic drugs stimulate the activation of the parasympathetic nervous system by activating receptors for acetylcholine. Anticholinergic drugs inhibit the parasympathetic nervous system by blocking the action of acetylcholine so that it cannot bind to receptors that initiate the parasympathetic response.
