Combined use of medications with anticholinergics may cause synergistic (supra-additive), additive, or antagonistic interactions, leading to no therapeutic effect or overdosing. [25] [26] Below listed are some medications or food that can interact with anticholinergics. Medications indicated for: Irregular heartbeat, e.g. disopyramide ...
Anticholinergics (anticholinergic agents) are substances that block the action of the acetylcholine (ACh) neurotransmitter at synapses in the central and peripheral nervous system. [ 1 ] [ 2 ] These agents inhibit the parasympathetic nervous system by selectively blocking the binding of ACh to its receptor in nerve cells .
ChEIs may be used as drugs for Alzheimer's and myasthenia gravis, and also as chemical weapons and insecticides. [ 4 ] [ 5 ] Side effects when used as drugs may include loss of appetite , nausea , vomiting , loose stools , vivid dreams at night, dehydration , rash , bradycardia , peptic ulcer disease , seizures , weight loss , rhinorrhea ...
Substances that may cause this toxidrome include cocaine, amphetamine and compounds based upon amphetamine's structure such as ephedrine , methamphetamine, phenylpropanolamine and pseudoephedrine. The bronchodilator salbutamol may also cause this toxidrome. It may appear very similar to the anticholinergic toxidrome, but is distinguished by ...
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 ...
The hypothesis states that a possible cause of AD is the reduced synthesis of acetylcholine, a neurotransmitter involved in both memory and learning, two important components of AD. Many current drug therapies for AD are centered on the cholinergic hypothesis, although not all have been effective.
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 increases the ...
Medications are used to reverse the symptoms of extrapyramidal side effects caused by antipsychotics or other drugs, by either directly or indirectly increasing dopaminergic neurotransmission. The treatment varies by the type of the EPS, but may involve anticholinergic agents such as procyclidine, benztropine, diphenhydramine, and trihexyphenidyl.
