Anticholinergics' Uses Flashcards
What is the use of anticholinergics?
Inhibit the actions of acetylcholine by occupying the acetylcholine receptors.
What is the other name of anticholinergics?
Parasympatholytics
What are the major body tissues affected by anticholinergics?
Heart, respiratory tract, GI tract, urinary bladder, eyes, and exocrine glands
When anticholinergics block the acetylcholine receptors, which system dominates?
Sympathetic (adrenergic) nervous system dominates
Which drugs have many responses similar to anticholinergics?
Adrenergic agonists
What are the major responses of anticholinergics?
GI motility, a decrease in salivation, dilation of pupils (mydriasis), and an increase in pulse rate. Other effects include decreased bladder contraction, which can result in urinary retention, and decresed rigidity and tremors related to neuromuscular excitement.
What is anticholinergic an antidote for?
For toxicity caused by cholinesterase inhibitors and organophosphate ingestion
Which class of drugs might anticholinergic block effects of?
Direct-acting parasympathomimetics such as BETHANECHOL (URECHOLINE) and PILOCARPINE and of indirect-acting parasympathomimetics such as PHYSOSTIGMINE and NEOSTIGMINE.
