Most drugs with parasympatholytic properties are anticholinergics. Parasympatholytic agents and sympathomimetic agents have similar effects to each other, although some differences between the two groups can be observed. For example, both cause mydriasis, but parasympatholytics reduce accommodation (cycloplegia), whereas sympathomimetics do not.
Mydriasis can be induced via modulation of adrenergic or cholinergic signalling. Drugs that can cause mydriasis include: Stimulants (typically monoaminergics) such as amphetamines, cocaine, MDMA, and mephedrone. Anticholinergics such as diphenhydramine, atropine, hyoscyamine, and scopolamine antagonize the muscarinic acetylcholine receptors in
Dilation and constriction of the pupil. Pupillary response is a physiological response that varies the size of the pupil, via the optic and oculomotor cranial nerve.. A constriction response (), [1] is the narrowing of the pupil, which may be caused by scleral buckles or drugs such as opiates/opioids or anti-hypertension medications.
pentobarbital – humane euthanasia of animals not to be used for food; pentoxyfylline – xanthine derivative used in as an antiinflammatory drug and in the prevention of endotoxemia; pergolide – dopamine receptor agonist used for the treatment of pituitary pars intermedia dysfunction in horses; phenobarbital – anti-convulsant used for ...
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 .
In some cases, there can be a physiological cause (like hepatic lipidosis); in some cases, it is a mental issue (like a new puppy in the house or the death of a companion); but in many cases, the ...
If you’re unsure whether your cat needs a medical evaluation, try calling the ASPCA Animal Poison Control Center (888-426-4435) or the Pet Poison Hotline (855-764-7661).
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 ...
