Used as a local anesthetic in medical and dental procedures due to its ability to block nerve impulses temporarily. It is effective in topical formulations for numbing skin and mucous membranes, providing short-term pain relief during minor surgeries, injections, or dental work. Its solubility profile allows for use in both aqueous and semi-solid preparations, making it suitable for sprays, gels, and creams. Often preferred in patients sensitive to ester-type anesthetics because of its lower allergenic potential.
