Why is atropine given?
Atropine is used to help reduce saliva, mucus, or other secretions in your airway during a surgery.
Atropine is also used to treat spasms in the stomach, intestines, bladder, or other organs.
Atropine is sometimes used as an antidote to treat certain types of poisoning..
Does atropine slow heart rate?
Atropine can cause bradycardia. Atropine has complex effects on heart rate: At low doses, atropine blocks M1 acetylcholine receptors in the parasympathetic ganglion controlling the SA node. This decreases heart rate (Bernheim 2004).
Why is atropine poisonous?
Ingestion of as little as a few drops of atropine in eye drop formulation can cause anticholinergic, or more specifically antimuscarinic, toxicity. The antimuscarinic toxidrome results from blockade of the neurotransmitter acetylcholine at central and peripheral muscarinic receptors.
How long does atropine last?
The blurred vision, caused by the atropine, will last for approximately seven days after the last instillation. The dilated pupil may remain for as long as 14 days.
Can atropine cause permanent dilation?
Permanent, fixed, dilated pupils may result from chronic atropinization, or large doses of atropine used in resuscitation.
How quickly does atropine work?
How long does atropine take to work? Atropine will start to reduce the amount of saliva within 5 to 30 minutes, and the effect will last approximately 4 to 6 hours.
Can eye dilation make you sleepy?
After: The dilation of your eyes may take a few hours to wear off. Have a friend take you home or to work, and wear sunglasses outside, since your eyes might be light-sensitive. Your eyes may feel tired and heavy after a glaucoma screening.
When would atropine be given?
Atropine is the first-line therapy (Class IIa) for symptomatic bradycardia in the absence of reversible causes. Treatments for bradydysrhythmias are indicated when there is a structural disease of the infra-nodal system or if the heart rate is less than 50 beats/min with unstable vital signs.
How does atropine affect the body?
Pharmacodynamics. Atropine reduces secretions in the mouth and respiratory passages, relieves the constriction and spasm of the respiratory passages, and may reduce the paralysis of respiration that results from toxic nerve agents which increase anticholinesterase activity in the central nervous system.
When should you not take atropine?
Atropine should be avoided with bradycardia caused by hypothermia and, in most cases, it will not be effective for Mobitz type II/Second-degree block type 2 or complete heart block.
How long can eyes stay dilated?
Dilating eye drops used for examination of the eyes usually last anywhere from 4 to 24 hours. This depends on the strength and type of the drop, and on the individual patient. Dilation can last longer in people with lighter colored eyes, and in some cases, may last longer than 24 hours.
What is atropine used to treat?
This medication is used before eye examinations (e.g., refraction) and to treat certain eye conditions (e.g., uveitis). It belongs to a class of drugs known as anticholinergics. Atropine works by widening (dilating) the pupil of the eye.
What class of drug is atropine?
Atropine is commonly classified as an anticholinergic or antiparasympathetic (parasympatholytic) drug. More precisely, however, it is termed an antimuscarinic agent since it antagonizes the muscarine-like actions of acetylcholine and other choline esters.
What happens if you give too much atropine?
Excess doses of atropine sulfate may cause side effects such as palpitations, dilated pupils, difficulty swallowing, hot dry skin, thirst, dizziness, restlessness, tremor, fatigue, and problems with coordination.
