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 long does atropine take to wear off?

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. Are there any side effects?

Does atropine stop the heart?

In the heart, atropine blocks the inhibitory effect of ACh on heart rate and contractility, potentially also leading to tachyarrhythmias6. These and other prominent effects of atropine have been exclusively attributed to its antagonism at muscarinic receptors7,8.

What is atropine used to treat?

Atropine is a prescription medicine used to treat the symptoms of low heart rate (bradycardia), reduce salivation and bronchial secretions before surgery or as an antidote for overdose of cholinergic drugs or mushroom poisoning.

What is use of atropine?

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.

Are atropine drops safe?

All three low concentrations were well-tolerated. “Current randomized controlled trials confirm the efficacy of low-concentration atropine compared with placebo, and 0.05% provides the best efficacy and safety in controlling myopia progression and axial length elongation,” Li and Yam wrote in their review.

What conditions will atropine not increase heart rate?

Atropine has little effect on systemic vascular resistance, myocardial perfusion pressure, or contractility. Atropine is indicated for the treatment of bradycardia associated with hypotension, second- and third-degree heart block, and slow idioventricular rhythms. Atropine is no longer recommended for asystole or PEA.

How does atropine speed up the heart?

By blocking parasympathetic (vagal) action on the heart, atropine increases the rate of discharge by the sinus node. Enhances conduction through the atrioventricular (AV) junction. Accelerates the heart rate, therby improving cardiac output.

When should you not take atropine?

The dosing for Atropine is 0.5 mg IV every 3-5 minutes as needed, and the maximum total dosage for administration is 3 mg. 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.

Does atropine increase BP?

However, when given by itself, atropine does not exert a striking or uniform effect on blood vessels or blood pressure. Systemic doses slightly raise systolic and lower diastolic pressures and can produce significant postural hypotension.
