Who should not take atropine?
myasthenia gravis, a skeletal muscle disorder. closed angle glaucoma. high blood pressure. coronary artery disease.
When should atropine be used?
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 fast do you give atropine?
Atropine should be administered by rapid IV push and may be repeated every 3-5 minutes, to a maximum dose of 3 mg.
How long does atropine take to 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.
What does atropine block?
Atropine is a clinically relevant anticholinergic drug, which blocks inhibitory effects of the parasympathetic neurotransmitter acetylcholine on heart rate leading to tachycardia. However, many cardiac effects of atropine cannot be adequately explained solely by its antagonism at muscarinic receptors.
What does atropine do to the heart?
Atropine increases the heart rate and improves the atrioventricular conduction by blocking the parasympathetic influences on the heart.
Is atropine a poison?
Side effects In overdoses, atropine is poisonous. Atropine is sometimes added to potentially addictive drugs, particularly antidiarrhea opioid drugs such as diphenoxylate or difenoxin, wherein the secretion-reducing effects of the atropine can also aid the antidiarrhea effects.
How long does IV atropine last?
Atropine is incompletely metabolised in the liver and is excreted in the urine as unchanged drug and metabolites. About 50% of the dose is excreted within 4 hours and 90% in 24 hours. The elimination half-life is about 2 to 5 hours.
How do you take atropine?

How often can you give atropine?
The recommended atropine dose for bradycardia is 0.5 mg IV every 3 to 5 minutes to a maximum total dose of 3 mg. Doses of atropine sulfate of <0.5 mg may paradoxically result in further slowing of the heart rate.
How does atropine work?
Mechanism Of Action Atropine competitively blocks the effects of acetylcholine, including excess acetylcholine due to organophosphorus poisoning, at muscarinic cholinergic receptors on smooth muscle, cardiac muscle, secretory gland cells, and in peripheral autonomic ganglia and the central nervous system.
Does atropine cause hallucinations?
Visual hallucinations are a major side effect of anticholinergic poisoning. Ophthalmic instillation of atropine has been documented to cause many central nervous sytstem symptoms, including hallucinations.
What type 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.
Is atropine a narcotic?
Controlled Substance: Diphenoxylate HCl and atropine sulfate tablets are classified as a Schedule V controlled substance by federal regulation. Diphenoxylate hydrochloride is chemically related to the narcotic analgesic meperidine.
