NON-TOXIC TOPICAL ANESTHETIC OPHTHALMIC COMPOSITIONS

摘要

Compositions and methods for prolonging the local anesthetic effect of site 1 sodium channel blockers and local anesthetics with minimal or reduced toxicity have been developed for ophthalmic use. It has been established that agents such as dexmedetomidine having alpha-2-adrenergic agonist and Hyperpolarization-activated cyclic nucleotide-gated channel antagonist activity can dramatically prolong the duration of nerve blockade when administered to the surface of, a compartment of or tissue adjacent to, the eye. A preferred active agent for prolonging the local anesthetic effect of site 1 sodium channel blockers or local anesthetics is Dexmedetomidine.
