Topical atropine is used as a cycloplegic, to temporarily paralyze the accommodation reflex, and as a mydriatic, to dilate the pupils. [15] Atropine degrades slowly, typically wearing off in 7 to 14 days, so it is generally used as a therapeutic mydriatic, whereas tropicamide (a shorter-acting cholinergic antagonist) or phenylephrine (an α-adrenergic agonist) is preferred as an aid to ...
According to their site of actions, cholinergic blocking drugs can be classified into two general types — antimuscarinic and antinicotinic agents. [1] Antimuscarinic agents (also known as muscarinic antagonists), including atropine and hyoscine, block acetylcholine at the muscarinic acetylcholine receptors.
Propantheline bromide is an antimuscarinic medication used for the treatment of excessive sweating (hyperhidrosis), cramps or spasms of the stomach, intestines (gut), or bladder, and involuntary urination . It can also be used to control the symptoms of irritable bowel syndrome (IBS) and similar conditions.
Anticholinergic drugs are used to treat a variety of conditions: Dizziness (including vertigo and motion sickness-related symptoms) Extrapyramidal symptoms, a potential side-effect of antipsychotic medications; Gastrointestinal disorders (e.g., peptic ulcers, diarrhea, pyloro spasm, diverticulitis, ulcerative colitis, nausea, and vomiting)
A muscarinic acetylcholine receptor antagonist, also simply known as a muscarinic antagonist or as an antimuscarinic agent, is a type of anticholinergic drug that blocks the activity of the muscarinic acetylcholine receptors (mAChRs). The muscarinic receptors are proteins involved in the transmission of signals through certain parts of the ...
Biperiden may lower the seizure-threshold. Some instances of dementia have been noted to correlate with chronic administration of anticholinergic medications such as biperiden for Parkinson's disease. [13] Peripheral side effects : Blurred vision, dry mouth, impaired sweating, abdominal discomfort, and obstipation are frequent.
Alpha 1 blockers cause vasodilation by relaxing smooth muscles that control blood vessel diameter, leading to lower blood pressure. [1] FDA-approved uses of these drugs include treating conditions like benign prostatic hyperplasia, hypertension, pheochromocytoma, extravasation management, and reversal of local anesthesia.
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
