Title
(EN) Methods for providing safe local anaesthesia
Abstract
(EN)
The invention provides a method for providing substantially safer local anaesthesia at a site in a patient, comprising: administering at a site in a patient in need thereof a biocompatible, biodegradable, controlled release formulation comprising a local anaesthetic, said local anaesthetic being present in a concentration effective to induce a localised condition selected from the group consisting of sensory anaesthesia, motor anaesthesia and combinations thereof, and said formulation providing a local anaesthesia having substantially improved safety but no prolonged effect relative to a formulation providing a pharmaceutically equivalent dose of local anaesthetic in immediate release form.
