Abstract
A drug delivery system provides sustained-release delivery of therapeutic biologically active compounds administered epidurally. In the preferred embodiment the biologically active compound is an opioid, which is encapsulated within the non-concentric internal aqueous chambers or bilayers of multivesicular liposomes. The opioid is released over an extended period of time when the liposomes are introduced epidurally as a single dose for sustained analgesia.
