Quiz: Understanding the Benefits of Epinephrine and Anticholinergics in Local Anesthesia Test your knowledge on the effects of epinephrine and anticholinergics in local anesthesia. Learn how epinephrine prolongs the duration of blockade and decreases toxicity, while anticholinergics provide a drier operative field. See if you can identify the advantages of using glycopyrrolate over atropine.
