Summary for Patent: 9,205,052
Title:Sustained-release liposomal anesthetic compositions
Abstract: The invention provides a method for obtaining local anesthetics encapsulated in liposomes, such as multi vesicular liposomes, with high encapsulation efficiency and slow release in vivo. When the encapsulated anesthetic is administered as a single intracutaneous dose, the duration of anesthesia and half-life of the drug at the local injection site is increased as compared to injection of unencapsulated anesthetic. The maximum tolerated dose of the encapsulated anesthetic is also markedly increased in the liposomal formulation over injection of unencapsulated anesthetic. These results show that the liposomal formulation of local anesthetic is useful for sustained local infiltration and nerve block anesthesia.
