TAC consists of which combination of drugs?

Explanation:
The main idea is a classic topical anesthesia approach that combines a potent local anesthetic with vasoconstrictors to maximize effect and minimize bleeding. Tetracaine provides strong, long-lasting surface anesthesia. Adrenaline (epinephrine) adds vasoconstriction to prolong the anesthetic effect and reduce bleeding at the site. Cocaine itself is both a local anesthetic and a powerful vasoconstrictor, contributing rapid onset and additional vasoconstriction. Together, they form the TAC combination. Other drug mixes replace one of these components (for example, using lidocaine, benzocaine, or procaine instead of cocaine or tetracaine), so they do not fit this specific combination.
