Question 12 of 35

That response is incorrect. None of the options provided were correct, as vasoconstrictors are not found in topical anesthetic agents.

Additionally, since anesthetics by themselves are vasodilators, this can speed the absorption of the anesthetic by the cardiovascular system. Combined with the fact that there is no vasoconstrictor present to slow absorption, this can increase possible overdose reactions and decrease the duration of action of the topical anesthetic.
