Abstract
An injectable formulation for a sustained-release of a local anesthetic is provided. The formulation comprises a pharmaceutically effective amount of a local anesthetic encapsulated into polymeric particles having a diameter from about 1 μm to about 4 μm. Such formulation prolongs analgesic effect, decreases toxicity, and allows loading larger doses, and at the same time is injectable directly at a patient's body site of the interest without generating a surgical wound. Methods of use and preparation are also provided.
