From the FDA Drug Label

Titrate according to heart rate, PR interval, blood pressure and symptoms. For Intravenous administration. Titrate based on heart rate, PR interval, blood pressure and symptoms.

The PR interval is a factor to consider when titrating the dose of atropine (IV). The drug labels suggest that the dose should be adjusted based on the patient's heart rate, PR interval, blood pressure, and symptoms. However, the labels do not provide complete details on the PR interval.

  • The labels mention titration based on the PR interval, but do not specify the exact parameters or target values for the PR interval.
  • The labels do not provide information on how to adjust the dose if the PR interval is prolonged or shortened.
  • The only relevant information is that the dose should be titrated based on the PR interval, among other factors 1, 1.
