What is the maximum total dose of atropine that can be administered for adult bradycardia?

In the management of adult bradycardia, atropine is a commonly used medication due to its ability to increase heart rate by blocking the effects of the vagus nerve on the heart. The standard guideline for the treatment of symptomatic bradycardia indicates that the maximum total dose of atropine that can be administered is 3 mg.

This limit is established considering the pharmacokinetic properties of atropine and the need to achieve an adequate therapeutic effect while minimizing the risk of adverse effects. Administering beyond this maximum amount does not provide significant additional benefit and may increase the likelihood of side effects such as tachycardia or increased myocardial oxygen demand.

Therefore, the recommended approach is to administer atropine in doses of 0.5 mg every 3 to 5 minutes until a total of 3 mg is reached, which ensures proper management of bradycardia while adhering to established safety guidelines.
