Do you know why articaine is combined with epinephrine?

Epinephrine is being used here as a vasoconstrictor.

Vasoconstrictors are tightening the blood vessels, therefore the perfusion with blood is lowered by epinephrine.

The LA (=local anesthetic) stays longer in the area it is administered in- leading to less side effects and a longer duration of effect.

LA are not harmless, though people might think it. Some can have serious side effects.
