Flaccid paralysis resulting from cholinergic crisis can be distinguished from myasthenia gravis by the use of the drug edrophonium (Tensilon), as it only worsens the paralysis caused by cholinergic crisis but strengthens the muscle response in the case of myasthenia gravis. Edrophonium is a cholinesterase inhibitor, hence it increases the ...
Scopolamine, an anticholinergic drug, was used to block cholinergic activity in young adults and induce memory impairments similar to those present in the elderly. The memory impairments were reversed when treated with physostigmine, a cholinergic agonist. However, reversing memory impairments in AD patients may not be this easy due to ...
A tensilon test, also called an edrophonium test, is a pharmacological test used for the diagnosis of certain neural diseases, especially myasthenia gravis. [1] It is also used to distinguish a myasthenic crisis from a cholinergic crisis in individuals undergoing treatment for myasthenia gravis.
Medication interventions are generally reserved for cases in which withdrawing the medication that caused the pseudoparkinsonism is either ineffective or infeasible. Anticholinergic medications are sometimes used to treat pseudoparkinsonism, but they can be difficult to tolerate when given chronically. Amantadine is sometimes used as well. It ...
Cholinergic blocking drugs are a group of drugs that block the action of acetylcholine (ACh), a neurotransmitter, in synapses of the cholinergic nervous system. [1] They block acetylcholine from binding to cholinergic receptors, namely the nicotinic and muscarinic receptors.
In a large clinical trial of the rivastigmine patch in 1,195 patients with Alzheimer's disease, the target dose of 9.5 mg/24-hour patch provided similar clinical effects (e.g. memory and thinking, activities of daily living, concentration) as the highest doses of rivastigmine capsules, but with one-third fewer reports of nausea and vomiting.

Cholinesterase reactivators are drugs that reverse the inhibition of cholinesterase by organophosphates or sulfonates. [1] They are used as antidote for treating organophosphate insecticide and nerve agent poisoning. [2] Organophosphates are used industrially in agricultural pesticides, and globally as agents of chemical warfare.
Glycopyrronium bromide affects the gastrointestinal tracts, liver and kidney but has a very limited effect on the brain and the central nervous system.In horse studies, after a single intravenous infusion, the observed tendencies of glycopyrronium followed a tri-exponential equation, by rapid disappearance from the blood followed by a prolonged terminal phase.
