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
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 ...
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.
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 .
Building on past research, a study conducted by the Indiana University School of Medicine suggests anticholinergic drugs of both the over-the-counter and prescription varieties are linked to ...
Tropicamide is an antimuscarinic drug that produces short acting mydriasis (dilation of the pupil) and cycloplegia [7] when applied as eye drops. It is used to allow better examination of the lens , vitreous humor , and retina .
Ipratropium bromide, sold under the brand name Atrovent among others, is a type of anticholinergic medication which is applied by different routes: inhaler, nebulizer, or nasal spray, for different reasons. [1] [2] The inhalant opens up the medium and large airways in the lungs.
Scopolamine, also known as hyoscine, [9] or Devil's Breath, [10] is a natural or synthetically produced tropane alkaloid and anticholinergic drug that is used as a medication to treat motion sickness [11] and postoperative nausea and vomiting. [12] [1] It is also sometimes used before surgery to decrease saliva. [1]
