About Topical Local Anesthetics.

Topical local anesthetics are a pharmacological class of surface-applied agents—primarily consisting of amino amides and amino esters—formulated as creams, gels, sprays, ointments, or patches.

They provide reversible loss of sensation by reversibly blocking voltage-gated sodium channels in sensory nerve membranes, thereby preventing the influx of sodium ions and inhibiting the generation and propagation of pain impulses along peripheral nerve fibers.

These agents are widely used to manage acute localized discomfort and facilitate minor procedures across dermatology, dentistry, ophthalmology, and otolaryngology, including venipuncture, laceration repair, and mucosal examinations.

They are also utilized for symptom relief in localized pain conditions, such as postherpetic neuralgia and minor anorectal disorders.
