Summary
Dental articaine is usually given with epinephrine. In patients on nonselective beta-blockers, unopposed alpha stimulation by epinephrine can cause hypertension with reflex bradycardia.
What this interaction means in plain words
Articaine and Timolol can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Articaine belongs to Central Nervous System; Timolol belongs to Cardiovascular.
Why it happens
Timolol blocks beta-2 mediated vasodilation, leaving epinephrine's alpha-mediated vasoconstriction unopposed.
What to do
Do not stop the beta-blocker before the procedure. Use the minimum effective epinephrine dose with aspiration to avoid intravascular injection, and monitor blood pressure and heart rate.
